What I'm looking for

Full-stack developer seeking real ownership and solving hard problems. I work independently, move fast, and deliver reliable results without constant supervision, yet I'm just as effective in a team: code reviews, clear written communication, and unblocking teammates. I want to build products that improve people's lives, with a team that values trust, clarity, and impact .

At InTimeTec, I designed and delivered backend services and REST APIs for fintech, SaaS, and IoT platforms. I led a six-engineer team, mentored developers, and developed automated tests that contributed to a 95% reduction in staging defects.

I also built FlowCommerce, a personal multi-tenant SaaS commerce platform using NestJS and Next.js. I designed its microservices architecture, added RabbitMQ-based asynchronous processing, and integrated AWS services for scalable compute, storage, and databases.
