Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
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!

COUNT monthly event: Kitchen service at Van Buren Center's shelter
COUNT monthly event: Kitchen service at Van Buren Center's shelter
Come assist Van Buren Shelter (https://ymcacolumbus.org/locations/vanburen) staff in serving dinners and cleaning up on the 3rd Tuesday of each month. Dinner for the women is 5-6 pm and for the families is 6:15-7:15 pm. There is ample free parking available in the shelter's lot. The recommended area to park is in green in the image above. There will be a new entrance for the time being. We are asking all volunteers to enter through the Donation Dock door, the orange mark on the image above. This door is located between the Single Adults and Family Shelter. You will see 2 large garage doors with a large green trash compactor in the center. Please head to the closest garage door to the building wall, with a ramp leading up. There, you will see a door with a sign stating instructions on how to enter the building. Please ring the doorbell, and a staff member will come and escort you into the building. If a staff member takes longer than 5 minutes, please call the front desk at 614-689-2020. This is a new process for us, and we do not want to keep you waiting! We appreciate your patience as we navigate this temporary change. The shelter needs a volunteer count the day before the event so sign-up ends Monday at 4:50 PM. Afterwards some of us go to the Omnipresent Atheists Weekly Meetup in progress to have a bit to eat or drink (http://www.meetup.com/omnipresentatheists/). Volunteers must be 14 or older. Since we will be working around families, the YMCA does not permit volunteering by individuals with convictions for violent or sexual crimes. The YMCA reserves the right to run background checks on volunteers. For questions, comment on this page or contact: Andrew, awhit12@yahoo.com, (614)937-5802 (cell). Please let Andrew know if you volunteer anytime other than our COUNT events so that he can count your hours toward our service record.

Drunken Philosophy: What’s up with all the AI hate?
Drunken Philosophy: What’s up with all the AI hate?
**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.
