TypeScript Developer
Senior Engineer — TypeScript across mobile, web, and API layers
I am a Senior TypeScript Developer based in London with five years of production TypeScript across mobile and web. Every project I have shipped in recent years has been strictly typed — React Native apps, Next.js frontends, Node.js API routes, and shared utility libraries.
TypeScript is not a checkbox for me — it is the primary tool for making codebases maintainable at scale. I use strict mode, discriminated unions, generic constraints, and utility types to eliminate entire classes of bugs before they reach production. At Hamilton Capital I led the TypeScript migration of a fintech platform across React, React Native, and Next.js — reducing runtime errors and unblocking team velocity.
On the mobile side, TypeScript is woven through every layer: typed navigation stacks with React Navigation, typed TanStack Query hooks, typed Zustand stores, and typed API response models validated at the boundary with Zod. On the web side, I have built typed design systems and typed analytics event schemas — ensuring that breaking changes are caught at compile time, not in production.

Tooling & Quality
Relevant Case Studies
Hamilton Capital — TypeScript Migration
Led TypeScript adoption across a fintech exchange platform (React.js, React Native, Next.js). Established strict type patterns, eliminated runtime bugs, and improved developer velocity.
Design System
Typed component library with strict prop interfaces, discriminated unions for variants, and generated design tokens. TypeScript enforced the contract between design and engineering.
Performance Audit
TypeScript tooling used throughout the audit pipeline — typed Core Web Vitals data models, typed analytics events, and typed configuration for measurement automation.
Looking for a TypeScript specialist?
Open to senior frontend or mobile roles in London and remote-first teams. Happy to discuss TypeScript architecture, migration strategy, or greenfield projects.
