**\*If interested, please whatsapp** [wa.me/+6588842635](wa.me/+6588842635) **or contact +65 8884 2635! Sign-ups *are only confirmed after contacting us and joining the WA group!\**** As we don't just wish to do Belumut, or just do Belumut + Gua Rimau, we are going to attempt to do the full CBR loop or also known as **Gunung Chemendong (846m)-Belumut(1,010m)-Rimau(889m) Loop.** Gunung Chemendong (846m) and Belumut (1,010m) is already an excellent (some say challenging) day-hike near Kluang, which is around 2 hours from Singapore. It is often used as a training hike to keep up in fitness, or as preparation for other hikes as it gives you experience and preparation for other tougher hike in Malaysia, like Ophir, other G7 mountains in Malaysia, or Kinabalu. Due to its location, makes it a solid day hike, still have a good dinner and be back in SG in 1 day. It is located in the Hutan Lipur Gunung Lumut (Mount Belumut Recreational Forest). We'll start with Chemendong first, crossing to the waterfall before heading to Belumut Peak, then the Rimau extension before turning back to the Belumut entrance so that it becomes a full loop (on GPS) and also be able to shower. We'll try to start as early as possible. Do note that this is an intense hike because you will do it with little/no sleep after Friday night. So do be mentally and physically prepared for it! You are also expected to get wet due to chance of rain, or crossing the streams! **Who is this for?** **=> People who wish to/can challenge themselves (I would say to the point of torture)** => People who have done full day hikes (e.g. Ophir) and wish to challenge themselves further => Wish to hike more than 12h and deal with different terrains such as crossing streams, going steep uphills, and then down, and then up again to test their mental fortitude => Training for tough hikes (high altitude hikes etc) => Generally suited for more experienced hikers who know they can last at least 12h hiking => Test yourself hiking with little/no sleep Do note that we will start and might descend when dark, so please bring headlights and we expect some level of fitness or hiking experience for the group! ***Hike Details*** ***The total distance is \~25km and total elevation gain is \~2000m+.The hike is around 12-16h in total, depending on your speed.*** This is almost 2x as long as Ophir Asahan hike. It can and will be extremely tiring on your mind, body and legs. It is generally tropical forest trail, with some rope portions, ladders, streams, waterpipes, waterfall, branches, insects (you name it you get it?). Do note that there will be lots of ups and downs so be mentally prepared for it. This is good for people who have some level of fitness and hiking experience. As this can be quite a challenging route, the group pace will be quite fast and we'll push at a certain speed. **There is also a cut-off timings which we'll enforce more strictly. If you fail to make it you will have to turn back unfortunately, as the distance is long. We aim to all be back down by 8pm.** **How many pax for the trip to happen?** Minimum **12 pax** to start the trip! A Whatsapp group will be set up and information sent through there. **Estimated Itinerary: (Saturday)** \~12.30 am : Meet @ Marsiling MRT 4.00 am: Breakfast 5.30 am: Reach Belumut Trailhead, start hike to Chemendong 10.00 am: Chemendong Peak (846m) 12.00 pm: Lata Tangga waterfall 2:30 pm: Belumut Summit (1,010m) 4:00 pm: Reach Rimau, descent to Trailhead 5:00 pm: Reach back Belumut Summit 7.00pm: Reach back trailhead, wash up and exit. 8.30 pm : Dinner (cost not included). Head back to SG 11.30 pm++ : Reach back SG ***Itinerary is subject to changes based on conditions and group speed and trek leader's discretion*** **Price: 175 SGD** Price includes: 2-ways Transport All associated Park Permits/ Fees LMT Trek Leader Local Hiking Guides Price excludes: All Personal expenses/Meals Visa Application (if any) This event is organized by LITTLE MONSTERS TRAVEL PTE LTD Travel Agent Licence No: 03117 Contact : +65 88842635 Email: [info@littlemonsterstravel.net](http://info@littlemonsterstravel.net/)

AI Engineer is coming to Singapore - and Google DeepMind (as a sponsor of the event) also wants to contribute to its general aura of awesomeness! Talks (subject to updates...): **"Prototyping fast in Antigravity" - Ivan Leo** Ivan has been using Google Antigravity to rapidly build and prototype systems-level Zig libraries like teul and gil. He’ll walk through his actual day-to-day workflow and share the biggest lessons he's learned about steering AI when writing low-level code. Before joining Google DeepMind, Ivan worked on building agents at Manus AI (SG) before its acquisition by Meta in 2026, and so brings a practical view on what it takes to turn agent capabilities into products developers can actually use. **"Robotics Planning with Gemini" - Chaitanya Jadhav & Anurag Roy** Seizing the opportunity to do a lightning talk at the intersection of Robotics (the subject of the April MeetUp) and Gemini, Anurag and Chaitanya will demonstrate how Gemini's multimodal and reasoning capabilities can power a pipeline that converts photos of an indoor space into a map and generates executable task plans for robots with different embodiments. **"Something cool with TTS" - Martin Andrews** In this lightning talk, Martin has been playing with the Gemini Flash TTS models - and will demo both its regular API, and how it can be incorporated into various workflows. **"From Lab to Laundry: Scaling Robot Autonomy in the Real World" - Daniel Ng & Siddharth Krishnan** Google DeepMind’s ALOHA accelerated robot learning and model development, yet a gap remains between successful lab demos and robots working reliably in production. Daniel and Siddharth share their experience deploying ALOHA-based teleoperated robots in real work environments to bridge this autonomy gap; and explain why teleoperation will play key role in autonomous deployment. Apparently, there will be hardware! **FOOD UPDATE :** Google has told us that **there WILL BE** pizza at the event \-\-\- Talks will start at 7:10pm (entry at 6:45pm) and end at around 9:00pm, at which point attendees can come up to the front for a bit of a chat with each other, and the speakers. Due to some recent security incidents at the venue please take note of the new DevSpace security procedures [https://bit.ly/devspace-security](https://bit.ly/devspace-security) Attendees will not be admitted later than 15min after the talks have started. As always, we're actively looking for more speakers - both '30 minutes long-form', and lightning talks. For the lightning talks, we welcome folks to come and talk about something cool they've done with keras, PyTorch, JAX and/or Deep Learning for 5-10mins (so, if you have slides, then #max=10). We believe that the key ingredient for the success of a Lightning Talk is simply the cool/interesting factor. It doesn't matter whether you're an expert or an enthusiastic beginner: Given the responses we have had to previous talks, we're sure there are lots of people who would love to hear what you've been playing with. If you're interested in talking, please just introduce yourself to Martin at one of the events.

Join us for an **advanced, hands-on session** focused on mastering best practices for development with Claude Code. We'll go beyond the basics to cover *planning, testing, and implementation, including deep dives into custom skills, subagents, hooks, context management, and maximising parallelisation using worktrees*. It's a walk-through of powerful agentic coding techniques on a live project, not slides about them. **What we'll cover** \- Claude Code configs\, plugins\, MCP\, and CLAUDE\.md \- The plan to review to implement workflow and why planning first prevents AI slop \- Power\-user territory: custom skills\, subagents\, and hooks\, and how to know when to reach for each \- Context management and progressive disclosure \- Worktrees: running multiple agents in parallel and trusting the output **Speakers** Aritejh — Senior Software Engineer working on agentic applications in the FinTech industry. He's used Claude Code, Codex, OpenCode, and GitHub Copilot to ship agentic systems in production. Manaswini — Senior Backend Engineer passionate about tackling the hardest problems in this space. She's drawn to the start-up world and volunteers across communities to support women in tech. Eileen — Lead at Women Devs SG. She enjoys supporting others on their engineering journey and believes AI will reshape software development, pushing engineers to keep adapting how they learn, build, and think. **Who is this for?** Software developers already using Claude Code (or another agentic coding tool) who want to push their workflow further. Whether you live and breathe these tools or you're using them sometimes and want to level up, this one's for you! **What to bring** \- Your laptop with Claude Code installed beforehand\. This is hands\-on\, and we'd rather spend the time on techniques than on setup \- Your current workflow questions as there will be Q&A throughout **About the partners** Women Devs SG is a Singapore community for women developers that organizes events, mentorship, and spaces where engineers at every stage can learn from each other. General Assembly is a global learning community and our venue partner for the evening, providing the space for us to gather and build together. A community initiative by Women Devs SG, in partnership with General Assembly. Registration starts at 6:30pm and the actual session at 7pm!

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
