Experience
Senior Software Engineer
Optimiser CRM 2021 - 2026
Designed and owned backend services for a Web3-enabled platform, building secure and scalable APIs using TypeScript, Node.js, and NestJS. Led the development of data models and backend pipelines to manage user activity, transactional workflows, and real-time system state, including blockchain-adjacent features. Integrated wallet interactions and asynchronous transaction flows, coordinating on-chain and off-chain state reliably. Migrated performance- and correctness-critical components from Node.js to Rust to improve concurrency safety and system reliability. Implemented real-time services with WebSockets, along with Redis-based caching, rate limiting, and idempotency to support high-concurrency workloads. Applied a security-first approach across authentication, authorization, input validation, and system design, while collaborating closely with product and frontend teams in a fast-paced, remote-first
