I design and ship production-grade full stack applications — from React/Next.js frontends and Node.js/NestJS APIs through PostgreSQL data layers, cloud-native deployments, and LLM-powered AI features. I own the full delivery cycle: architecture, implementation, testing, and production reliability.

8 years of building things that scale. Currently deepening into AI engineering — LLM orchestration, RAG pipelines, voice AI, and agentic workflows.

🏗️ Micro Frontend Architecture — Webpack Module Federation, Monorepo (Turborepo/Nx), enterprise design systems across distributed teams

🤖 AI / LLM Engineering — Multi-provider orchestration (OpenAI + Gemini), voice pipelines (LiveKit + Deepgram), agentic workflows, RAG + Pinecone

📱 Cross-Platform Mobile — React Native / Expo, offline-first architecture, 60fps Reanimated animations, Expo EAS deployments

⚙️ Backend Services — RESTful & GraphQL APIs, NestJS, PostgreSQL schema design and query optimization, Redis, Docker / AWS

Enterprise · Universal Weather and Aviation · 5 distributed teams · Production

Built for five distributed teams shipping to production simultaneously. Webpack Module Federation shell app with dynamic route registration, centralized auth, and runtime dependency resolution. 50+ component design system with full WCAG/AODA compliance. Sabre REST + GraphQL via Apollo Client with normalized caching. Feature-flagged CI/CD on AWS.

Stack:

AI Platform · Multi-provider LLM orchestration · Real-time voice · Production

Multi-provider LLM layer (OpenAI + Gemini) with provider-agnostic failover — zero client-side changes on model switch. Hybrid GraphQL + REST API architecture. WebSocket-driven real-time mock interviews. Migrating voice pipeline to LiveKit Agents + Deepgram (~15x cost reduction vs Vapi at $0.10/session).

Stack:

Full Stack · Next.js 14 + NestJS + PostgreSQL · TypeScript end-to-end

NestJS REST API with RBAC guards, dependency injection, and middleware pipelines. PostgreSQL query optimization: dashboard response 3.5s → under 500ms on 10,000+ records. SSR/ISR rendering achieving sub-1.2s page loads.

Stack:

React Native / Expo · Turborepo Monorepo · Cross-platform mobile

60fps Reanimated animations with GPU-accelerated glassmorphism UI. Turborepo monorepo sharing TypeScript schemas, email templates, and components across NestJS backend and Expo mobile client.

Stack:

Multi-vendor e-commerce · Node.js + Next.js · Polyglot DB

Polyglot DB architecture — MySQL for transactional integrity (orders, inventory), MongoDB for flexible content (product descriptions, vendor profiles). Per-route SSR/ISR/CSR strategy. Versioned payment processor integration with idempotency guarantees and webhook-based confirmations.

Stack:

React Native · Offline-first · Enterprise field auditing

Full offline audit workflows with zero server dependency. Conflict-aware sync engine using timestamp-based versioning and field-level merge on reconnect. Configurable drag-and-drop form engine with conditional logic — zero engineering changes needed for new inspection templates.
