Software engineering · Full stack

Backend depth.Full-stack delivery.

I turn complex problems into products that work. From the first decisions to the systems that keep them running.

Decisions thatmake a difference.

My engineering practice

6,000users / hour1

≈30% of the performance plan implemented

Making room for the peaks

I designed the performance roadmap and implemented changes with the team. With about 30% of the plan completed, the platform supported production peaks of up to 6,000 users per hour through the registration journey.

Less work before more resources

I redesigned ingestion logic and implemented changes with the team, reducing daily upsert combinations from over 30 million to thousands, using streaming and batching.

Plate 05Beyond the code

Engineer. Label founder.Always a student.

I’ve worked professionally in software since 2022, run my own record label, and study biomedical sciences. I like understanding how systems work—and putting that understanding into practice.
