PROFILE
Full-stack developer with 3+ years of experience building production-ready applications across the stack — React/Next.js on the front end,
Node.js/NestJS on the back end. Strong in state architecture, real-time data sync, API design, and performance optimization. Focused on
scalable, end-to-end solutions and clean UI.

EMPLOYMENT HISTORY
Full-stack developer, ABCloudz July 2025 — July 2026
Transitioned into a full-stack role on the same internal enterprise platform, taking ownership of backend services powering the real-time
features I had previously built on the front end.
Responsibilities:
Designed REST/GraphQL API endpoints and WebSocket real-time services with NestJS, end-to-end (backend + frontend)
Modeled and optimized data in PostgreSQL and MongoDB; introduced Redis caching for high-traffic endpoints
Containerized services with Docker and maintained CI/CD pipelines
Adopted an AI-first workflow with Claude Code (agentic scaffolding/refactoring); authored project CLAUDE.md rules and skills used for
first-pass code review and Playwright test suites
Key Achievements:
Migrated a core feature from REST polling to WebSocket, cutting update latency by ~40% and reducing server load
Reduced query response times by ~30% through PostgreSQL index and schema optimization
Set up a CI/CD pipeline with Docker, reducing deploy time from ~25 minutes to under 8
Front-end developer, ABCloudz Jun 2023 — July 2025
Worked on a large internal enterprise platform for data visualization, system management, and automation. Delivered end-to-end features,
collaborated with designers and backend engineers, and contributed to architectural decisions.
Responsibilities:
Implemented UI and complex app state with React/Next.js
Integrated REST APIs & WebSockets; built reusable components and maintained Storybook
Optimized performance and rendering
Key Achievements:
Implemented a backend-synchronized state tree system with persistence, improving data consistency across the app
Reduced unnecessary re-renders on critical screens by ~35% through refactoring and memoization strategy
Improved API data handling by redesigning fetch logic with RTK Query and RxJS
