What I'm looking for

I seek senior engineering roles focused on TypeScript-led frontend or full-stack work, collaborative teams, technical leadership opportunities, and measurable impact on product performance.

I am a Senior TypeScript Developer with 7+ years building scalable, production-grade web applications for product companies, digital agencies, and SaaS startups. I specialize in TypeScript-driven frontend and full-stack development using React, Next.js, and Node.js, with a strong focus on type safety, maintainable architecture, and performance optimization.

At Northbay Software Studio I led TypeScript adoption across multiple client and internal applications, acted as technical lead on projects coordinating 4–6 frontend developers, and delivered performance improvements of 18–25% on core user flows. I collaborate closely with designers, product owners, and backend engineers to define TypeScript-based API contracts and reduce integration issues.

My background includes building and maintaining design-system components, refactoring legacy JavaScript to TypeScript, improving build pipelines, and implementing testing with Jest and React Testing Library. I bring a pragmatic, team-oriented approach to delivering reliable, business-critical software.
