• Feature Development: Shipped end-to-end features across 3+ client projects spanning React, React Native, Next.js, and Flutter, covering both web and mobile surfaces. • API Design: Engineered type-safe REST APIs using NestJS, TypeScript, and Zod validation, reducing integration bugs by enforcing strict contracts between frontend and backend. • Bug Fixes & Debugging: Triaged and resolved 20+ production issues across web and mobile platforms, including state management regressions, layout breakages, and failed API integrations. • Performance Optimisation: Cut initial load time by ~40% on a React Native app through code-splitting, lazy loading, and targeted render optimisation. • Cross-Platform Consistency: Unified iOS and Android business logic across 2 projects, eliminating platform-specific edge cases and ensuring consistent behaviour on 10+ device configurations. • Code Reviews: Conducted peer reviews across 3 active codebases, flagging typing violations, anti-patterns, and architectural drift before merges. • Database Design: Modelled normalised PostgreSQL schemas for 2 client applications, structuring complex many-to-many relationships to support scalable query patterns.
