What I'm looking for

I'm looking for a senior engineering role where I can own features end to end and work on meaningful product and architecture problems. I enjoy frontend and full-stack development, performance, reliability, developer tooling, and solving production issues. I prefer remote teams with strong engineering practices and autonomy.

I'm a Senior Software Engineer with 7+ years of experience, mainly working with React, Next.js, TypeScript and Node.js.

Most of my work has been on production systems where I've owned features end to end rather than only the UI. In my current project, I work on an enterprise workflow platform built with Next.js, PostgreSQL and Prisma. I've worked across workflow management, document processing, search, database changes, E2E testing and production releases. I improved one of our search paths from around 40ms to 12ms and built a Playwright suite of 380+ tests that runs in roughly two minutes.

Previously, I worked on large public-sector platforms including DIGIT Urban and Sanitation. I built React micro-frontends, reusable components and common hooks, and worked on water and sanitation systems, payment integrations, accessibility and localization.

More recently, I've been working with LLM integrations for document processing and exploring MCP reliability. I maintain MCP Failure Lab, an open-source toolkit for testing how MCP clients and servers behave under failures such as delays, hangs and disconnects.

I'm interested in Senior Software Engineer, Frontend, Full Stack and Product Engineering roles where I can work on architecture, performance and real product problems. I enjoy taking ownership of systems, debugging difficult production issues and simplifying things that have become unnecessarily complicated.
