What I'm looking for

I’m looking for a quality-driven team where I can own full-stack features end to end, build performant SaaS products, and collaborate closely across engineering, data, and product—preferably in fast-moving remote or hybrid environments.

I’m a Senior Full Stack Software Engineer with 10+ years building user-focused web applications, specialized in React, Next.js, TypeScript, Node.js, and Python (FastAPI). I’m especially energized by AI-assisted development and delivery of production-grade systems in fast-paced SaaS environments.

At Datafold (Jan 2023–Present), I led development of scalable full-stack applications, owning end-to-end frontend features and building backend services and internal tooling with FastAPI and Node.js. I designed frontend architecture with Redux/RTK, React Query, and modern TypeScript patterns, and I optimized performance with caching, lazy loading, and query tuning for data-heavy experiences.

Before that, at Unbabel (Oct 2019–Dec 2022) I built translation and communication platform features, supporting multilingual workflows and AI-assisted tooling. I’ve also developed fintech and cybersecurity-focused SaaS capabilities at Mash and BitSight, and contributed to enterprise web applications at NTT DATA—always with a quality-first mindset, clean architecture, and strong cross-functional collaboration in remote and hybrid teams.
