JTA: The Data Scientists

What a fantastic two days at Data Makers Fest (May 5–6) at the iconic Alfândega do Porto! 🎉 JTA was proud to have a booth at the event, and our CEO Duarte Gomes had the pleasure of hosting two great sessions: Lessons Learned from Optimizing a Spark Streaming Pipeline with Joao Antonio — How a focused review of a Spark Streaming pipeline exposed hidden architectural issues and sparked a broader discussion on partitioning, metadata management, and flexible table formats. Lessons Learned after 6.7T Events through PostgreSQL Queues with Aris Tzoumas — A six-year journey scaling PostgreSQL to 100,000 events per second, proving it can compete with dedicated systems like Kafka while keeping things simple and reliable. A huge thank you to the Data Makers Fest team for putting together such a high-quality event. Already looking forward to the next one! 🚀 #DataMakersFest #DataEngineering #lifejta #BigData #Streaming

🏆 National Top 10 — Red Bull Basement 2026 We're incredibly proud to share that Ana Rita, one of our own at JTA — The Data Scientists, has just made it to the National Top 10 of Red Bull Basement 2026. Her project? A Skin Lesion Detection System for Skin Cancer Prevention — a deep learning-powered solution designed to support the initial triage of skin lesions using image analysis and patient data. The goal is ambitious but deeply human: make skin cancer prevention faster, smarter, and more accessible for everyone. By identifying low-risk situations early and flagging cases that may need urgent attention, Ana Rita's system could help reduce pressure on our national health system — freeing up critical appointments for those who need them most. Congratulations, Ana Rita. We couldn't be prouder. 🚀 #RedBullBasement #DataScience #AI #HealthTech #SkinCancer #DeepLearning #Innovation #JTA #NationalTop10
