Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized!

[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations. If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!). **HOW IT WORKS** **Step 1: Bring a topic** Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event. **Step 2: Circle up & share** We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds. **Step 3: Walk, talk & float** We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!" **Step 4: Feel more alive** Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times. *For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)* **HOW TO BRING A GREAT TOPIC** A great topic = something you're genuinely curious about. Recent topics include: * "What are you passionate about right now?" * "What makes a good friend?" * "What's a belief you used to hold that you've completely changed?" * "How do you want to be remembered?" * "What would you do if money wasn't a factor?" Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter. **WHAT TO EXPECT** This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.* But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here. **FAQ** * Wear casual athletic attire and sneakers. It's a long walk! * We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space. * We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space. * Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know. * Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic! **LOGISTICS** * If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event. * This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs. * There's a restroom along the route at [Tuttle Park Community Center](https://maps.app.goo.gl/KTZJgLE1CrrbRNmJ7), which is about two‑thirds of the way from [Clinton-Como Park](https://maps.app.goo.gl/z8Cx8evwLiWundMe8) to our [turnback point](https://maps.app.goo.gl/ZXk7qUVszLQ8EJxHA). * Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details. * If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**.

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!

**History** The history of [Blendon Woods Metro Park](https://www.metroparks.net/parks-and-trails/blendon-woods/) began long before its 1951 opening, rooted in a landscape of rugged ridges and deep ravines that made the land unsuitable for traditional farming. In 1945, a report proposing a metropolitan park system for Franklin County specifically highlighted these cliffs of Bedford Shale as some of the "wildest land in the vicinity". Following this recommendation, the recently formed park district purchased the first 229 acres in early 1949. Because the terrain was so uneven, developers had to cut a mile-and-a-half-long roadway through dense woods just to bring in heavy equipment. This initial preservation effort ensured that the mature second-growth hardwood forests remained largely untouched by the urban expansion spreading toward Westerville. Opening day arrived on Labor Day, September 3, 1951, marking Blendon Woods as the second park in the Columbus and Franklin County Metro Parks system. The final push to open was a frantic race; the State Highway Department only finished the primary gravel access road four days before the gates opened. Early staff members, consisting of just four full-time employees, had to hand-dig pit toilets and learn construction skills on the fly to build the first picnic shelters. Despite the dusty conditions and limited facilities, the park was an immediate success, drawing massive crowds from across Central Ohio. By the end of the 1950s, annual visitation had already climbed to over 190,000 people. As the surrounding suburbs grew in the 1960s, the park faced severe overcrowding that threatened its natural habitats. In response, Franklin County voters passed the first Metro Parks levy in 1960, providing the funds necessary for a decade of steady expansion. During this era, the park nearly doubled in size, growing from 264 acres to over 570 acres by 1968. Planners also addressed a critical water shortage by collaborating with the U.S. Soil and Conservation Service to build a lake in 1964. This body of water originally served as a temporary reservoir before its role shifted toward conservation and wildlife support. The 1970s marked a transition toward the specialized wildlife and educational focus for which the park is known today. In 1971, the Walden Waterfowl Refuge was established around the 11-acre Thoreau Lake, creating a sanctuary that remains restricted to provide a quiet habitat for migratory birds. A formal nature center was also developed during this period, expanding on the guided Sunday walks that had been a park staple since the early 1950s. The park’s famous "Monarch Mansion" also became a prominent fixture, starting a long tradition of raising and releasing thousands of monarch butterflies each September. These initiatives cemented the park’s reputation as a premier destination for birders and nature enthusiasts. In more recent decades, Blendon Woods has continued to modernize while maintaining its wilderness character. The 10-acre Natural Play Area was added in 2017, encouraging kids to explore the ravines and woods off-trail. This was followed by the opening of a $1.5 million inclusive playground in April 2025, designed to accommodate children of all physical abilities. The nature center also underwent major renovations to include immersive, three-dimensional exhibits and a new butterfly house. Today, the park encompasses 653 acres, preserving a unique geologic and biological corridor amidst the bustling Westerville and Northeast Columbus area. **Map of the Park** Here is a map of [Blendon Woods](https://www.metroparks.net/wp-content/uploads/2025/05/BLN_map_Inclusive-Playground-and-Butterfly-Trail_May-2025_1980px.png). **Summary** For this event, we will hike the Lake View, Hickory Ridge, Ripple Rock, Overlook, Brookside, and Sugarbush Trails. This sounds like a lot, but it will really be only a little over five miles. Blendon Woods has a few hills here and there, but it's not one of the more strenuous metro parks. **Where We'll Meet** We'll meet just in front of the Nature Center. This is about a mile into the park from the main entrance. You have to go past the Ranger Station and the Shadblow Reservable Area to get to it, so don't stop too early at the Ranger Station and get it confused with the Nature Center. **After the Hike** Afterward, we will head over to [Forbidden Root Restaurant & Brewery](https://forbiddenroot.com/restaurants/columbus-ohio/) at Easton for [drinks](https://forbiddenroot.com/restaurants/columbus-ohio/#dinner-menu) and [food](https://forbiddenroot.com/wp-content/uploads/Cbus-Food.pdf). We should be there by 5 if you can't make the hike and just want to join us for drinks. The brewery's actual address is [4080 Worth Ave, Columbus, OH 43219](https://www.google.com/maps/place/4080+Worth+Ave,+Columbus,+OH+43219/data=!4m2!3m1!1s0x88388a86d10b6619:0x4d42b470a5cf11d3?sa=X&ved=1t:242&ictx=111); however, I recommend pointing your GPS to the [Worth Garage](https://www.google.com/maps/place/Worth+Garage/@40.0542293,-82.9137962,17z/data=!3m1!4b1!4m6!3m5!1s0x88388b4df6082825:0x17582f0eccd9dda1!8m2!3d40.0542293!4d-82.9137962!16s%2Fg%2F11rzfvvv8b?entry=ttu&g_ep=EgoyMDI2MDQxNS4wIKXMDSoASAFQAw%3D%3D) across the street. Parking in this garage is free as long as you're not on the first floor, and it is literally right next to the brewery.

**Abstract:** This is a practical playbook for building a production-grade data lakehouse. It walks through foundational principles — naming conventions, least-privilege access, automated CI/CD testing — before diving into medallion architecture. Furthermore, metadata-driven design patterns show how configuration tables and dynamic notebook orchestration eliminates hard-coded pipelines. The deck covers star schema modeling, guidance on choosing between Spark, Pandas, and SQL, and data quality enforcement using DQX with YAML data contracts. Finally, we dive into security best practices and performance optimizations. **Host:** Justin Shea, Mehdi Jeddi, Erik Pak, and Sou-Cheng Choi **Talk Format:** This is a hybrid event.
