Capx AI

May 2025 - May 2026 Uttarakhand, India

  • Architected a Supabase Postgres read replica strategy to offload 80% read traffic from the primary database. Optimized historical price chart performance by designing TimescaleDB hypertables with materialized OHLCV views.
  • Migrated infrastructure from AWS App Runner to Cloudflare Containers, implementing a 3-tier edge architecture (Worker → Durable Object → Container) with runtime secrets injection and auto-sleep lifecycle management, reducing hosting costs by 60%.
  • Deployed Solidity smart contracts including a Uniswap V2 fork with custom fee logic, UUPS upgradeable proxies, EIP-1167 minimal proxy factories, Governance contracts enabling forced early settlement and allocation claims for presale winners.
  • Built & managed a real-time WebSocket broadcaster serving 11 data channels via AWS API Gateway with Redis caching. Secured WebSocket infrastructure against DDoS attacks with signature validation, per-connection rate limiting and violation tracking with auto-blocking.

  • Built a full-stack AI image-generation platform where users train personalized LoRA models from their own photos and generate custom images, professional headshots, fashion try-ons, and styled portraits, using React 18, Vite, TailwindCSS, and an Express (Node.js) REST API
  • Engineered an asynchronous AI pipeline integrating Fal.ai and Replicate for Flux LoRA training and inference, using webhook callbacks and Server-Sent Events (SSE) to push real-time training status to clients without polling
  • Implemented secure authentication by verifying Supabase-issued ES256 JWTs against a remote JWKS endpoint with the jose library, hardening the API by replacing the legacy shared-secret HS256 scheme and adding CORS origin-verification middleware
  • Integrated Stripe subscriptions with signature-verified webhooks to drive a credit-based usage system across tiered plans, including atomic credit deduction and automatic restoration on failed generations
  • Architected scalable frontend state using React Context with useReducer and TanStack Query for cached, optimistic data fetching; instrumented the stack with PostHog analytics and shipped via Dockerized CI/CD (GitHub Actions) to an Azure VM and Vercel
