What's your current role and focus?
I'm a Lead Frontend Developer at Intermarché Portugal, working remotely on a high-traffic platform serving 100k+ users. My focus is on performance, scalability, and delivering business impact through clean engineering.
How do you handle legacy codebase migrations?
Incrementally — never a full rewrite. I isolate legacy boundaries, introduce a strangler layer, and migrate module by module with feature parity tests at each step. The goal is zero downtime and a codebase the team can actually own afterward.
How do you approach systems under high user load?
At IP-LABEL I worked within a dedicated load testing team using WebLoad to reproduce user scenarios via HTTP and Selenium, then inject virtual clients to simulate high traffic. We pushed systems to an all-time high of 40 million parallel users — stress-testing at a scale most engineers never get near.
Can you give an example of measurable impact from your work?
At IP-LABEL I engineered a ClickHouse-based datalake that reduced cloud storage costs by 7x compared to AWS S3, while improving query performance for analytics dashboards. I also built UI/UX improvements that shipped to 100k+ users at Intermarché Portugal.
