I’m a Frontend Web Developer with over five years of experience building application interfaces across accounting, finance, e-commerce, event management, human resources, and Web3/crypto—supporting clients in North America and Western Europe. I thrive on turning complex requirements into solution-oriented UI and UX.

In my most recent role as a freelance Frontend Developer for a real-time crypto intelligence dashboard, I designed and delivered a multi-feed platform across two major versions. I built a strict, type-safe frontend using Next.js (App Router), React 19, TypeScript, Zustand, and TanStack React Query, including localStorage persistence with schema migrations.

I’m especially proud of the real-time architecture: I engineered a resilient WebSocket pipeline with heartbeat monitoring, exponential backoff reconnection, race-condition prevention, and out-of-order message queuing to ensure zero data loss under unreliable networks. I also implemented a config-driven, extensible card system and advanced feed filtering with real-time overrides and optimistic updates across the in-memory cache.

As a Frontend Team Lead at AGInfoTech, I manage a team of 4 developers while ensuring delivery meets client requirements and expected timelines. I focus on state management best practices, mentor developers, collaborate tightly with backend/DevOps/QA, and continuously improve maintainability, performance, and developer workflow.
