What I'm looking for

I’m looking to build and scale high-impact fintech SaaS, owning systems end to end. I want a team that values clean architecture, performance, async collaboration across product/design, and opportunities where I can mentor and raise engineering quality.

I’m a FullStackEngineer with 10+ years of experience building scalable web apps, APIs, and cloud systems. I’m strong across the stack—React, Next.js, Node.js, Python, Php, and AWS—and I focus on clean architecture, performance, and delivering features that improve product outcomes.

I like owning systems end to end and collaborating across engineering, product, and design while working async across multiple time zones. In recent roles, I’ve built Node.js and GraphQL microservices, improved payment performance by 40% with caching and routing optimizations, and automated compliance workflows using OpenAI for document processing.
