Senior full-stack engineer specializing in React, Next.js, Angular (frontend) + Node.js (backend/microservices). I build high-performance, reliable systems from MVP to enterprise scale.

Core strengths:

• Frontend: Pixel-perfect, responsive UIs with React/Next.js (App Router, SSR/SSG), TypeScript, - Tailwind/MUI/Chakra, Framer Motion animations. Mobile conversions via Capacitor/React Native.
• Backend: Node.js (Express/NestJS), REST/GraphQL APIs, high-load optimization (1M+ records/day).
• Databases at scale: PostgreSQL, MongoDB, Redis handled production >60TB clusters.
• Testing & Quality: Playwright/Cypress E2E, unit/integration, CI/CD (GitHub Actions), Docker.
• Extras: Chrome/Edge extensions (MV3), Web3/smart contracts, SaaS/task platforms (Jira-like), performance tuning (Lighthouse 95+).
• AI responsibly: Accelerate prototyping/boilerplate, but architecture, logic, security, and final code always 100% mine.Proven track record: Led teams in large orgs (400+ devs), built full ecosystems (Taco Bell-like fast-food platforms in pure JS), optimized massive back-offices.

Clients say: "Project after Val is a company that embodies inclusion, professionalism, strong architecture, and getting it done right."
