Feb 2025 - Present

Frontend (Primary): Built responsive, accessible user interfaces using React, Next.js and TypeScript; integrated REST, GraphQL and WebSocket APIs; created reusable component libraries and improved performance through code-splitting and bundle optimisations. Backend & Database: Developed scalable REST APIs using NestJS with TypeORM and PostgreSQL; designed relational schemas, wrote optimised queries, and containerised services with Docker for consistent local and production environments. Blockchain & Smart Contracts: Designed, implemented and deployed Solidity contracts (Hardhat/Foundry) and Solana programs in Rust with Anchor; focused on gas optimisation, security hardening, and modular/upgradable on-chain architectures for token, claim and reward mechanisms. Release-Quality Practices: Established unit and integration tests, CI/CD pipelines and audit-ready documentation; performed security reviews and participated in external audits to ensure safe deployments. Collaboration & Impact: Delivered end-to-end features spanning UI to on-chain logic; worked closely with product, security and infrastructure teams, conducted code reviews, and mentored junior engineers to increase development velocity and reliability.
