About

Senior Python & Data Engineer with 7+ years across cloud architectures (Azure, AWS), backend systems and end-to-end data pipelines. I've led a 6-person engineering team, built Medallion pipelines processing 500M+ rows with Spark, Databricks and Airflow, and designed real-time video analytics handling 200 concurrent streams with computer vision and LLM-powered search.

Alongside engineering, I co-founded an education startup and trained 40+ developers — over 80% hired within months. I work best in distributed, international teams, turning business problems into scalable data systems.

In love with 📚 Open Source, ☕ Coffee & 🎮 Games. Proactive and always helping the next, captivated by problem solving.

Oleg Zaidiner — AI-First Tech Leader, Focuz (managed Lucas)

I worked with Lucas for over a year at Focuz, where he joined us early — when the product was still taking shape and the team was small. That context matters: being useful at a prototype stage, when requirements shift weekly and there's no playbook, takes a specific kind of person. More than the technical work, he was someone you could count on to show up, do what he said he'd do, and keep a decent attitude even when things were uncertain — which in an early-stage startup is a lot of the time. He's a good person to work with, and I hope our paths cross again.

Łukasz Wąsowicz — Backend Engineer, Focuz (same team)

Lucas is a strong backend engineer with deep experience in Docker and container-based services. He consistently demonstrates ownership, clear communication, and a reliable problem-solving mindset. Working with him was always smooth and productive — he brings both technical expertise and a collaborative attitude to the team.

Sapna Madaan — People & Culture Architect (managed Lucas)

An exceptional professional who demonstrated agility and strong organizational impact during our time collaborating on global workplace initiatives.

Victor Sousa — Backend Developer (C# / .NET / Java), same project

It is with great enthusiasm that I recommend Lucas as an elite software developer and a highly skilled complex problem solver. His passion for programming, impressive technical skills, and talent for solving challenges make him an invaluable asset to any development team.

Igor Nunes Teixeira — Software Engineer at XP Inc., same project

Lucas Nunes is one of those professionals who leave an indelible mark on every project they are involved in. His approach as a software developer goes beyond code: he embodies the essence of leadership and mentorship. With a rare combination of technical intuition and communication skills, Lucas transforms complex challenges into elegant, educational solutions. Having him as a mentor was a turning point in my professional trajectory. I recommend Lucas blindly for any project seeking excellence and a lasting impact.

Nicholas Ribeiro — Full Stack AI Engineer, same project

An exceptionally talented and dedicated professional. During our time together, I witnessed his incredible problem-solving ability, creativity, and patience. His passion for work is evident in everything he does, and he is always willing to go above and beyond to achieve extraordinary results.

Ramon Rodrigo Machado — IT Manager at BDO Brazil

Excellent professional, communicative, and extremely intelligent. He has great potential ahead — a backend developer (Python) with a true passion for data analytics! He supported me with security for development and cloud management. Best regards.

Victor Rodrigues — Video Editor & Content Creator, project together

Lucas is a great professional with incredible creativity in his projects. He is always focused on innovation, and I am very proud to have had the opportunity to complete a project together with him.

Willian Pires Vareiro — Mechanical Engineer, World Caldeiraria

An excellent professional with an outstanding vision for problem-solving and strong proficiency in Python, Scilab, and Matlab programming.

Guilherme Maximo — Trainee @ Itaú Unibanco, project together

Lucas is a great professional. He is patient, communicative, proactive, and extremely competent. At all times, he showed a strong willingness to help and support the resolution of our project in the most rational and effective way. I would absolutely work with him again!
