VIJAY P.

I build complete web products. The interface your users touch, the API behind it, the database under that, and the AI layer on top when it actually earns its place. Most clients hire me because they don't want to stitch together separate frontend, backend, and AI developers. I take full ownership of a product from architecture to launch, ensuring nothing breaks in the gap between "the design looks great" and "it actually scales in production." 📊 Key Metrics & Availability: → Proven Scale: 1,600+ hours billed on Upwork with a history of long-term client retention. → Velocity: 12+ production apps shipped across SaaS, Fintech, E-commerce, and AI. → Availability: Fully available right now for 30–40 hours/week. I overlap heavily with US/EU business hours. 🚀 MILESTONES & PROOF OF SCALE → High-Traffic Scale: Managed production systems handling 10M+ requests per day with databases scaling up to 7B+ rows under long-term SaaS contracts. → Performance Optimization: Cut legacy API latency by 90% under heavy load, dropping response times from 1.5 seconds down to a crisp 50–150ms. → Cloud Cost Reduction: Cut server infrastructure costs by more than half with zero downtime (optimized a DigitalOcean setup from $1,600/mo to $700/mo) and reconfigured AWS SQS pipelines to cut monthly queue costs by 90%. 🛠️ LIVE PRODUCTION PRODUCTS → Nudgify – High-traffic social proof platform handling 10M+ requests/day. Led the infrastructure overhaul that cut server costs by over 50%. → Aura AI – Live, reviewed, and officially approved on the Shopify App Store. Search this name on the App Store to see it. Built on custom search architectures and the GraphQL Admin API. → Bookify.AI – Advanced chat-with-PDF SaaS utilizing OpenAI streaming, vector databases, and automated Stripe subscription billing. → Giveable.AI – Predictive AI fundraising platform designed to optimize donor uplift and handle secure data streams. → Memberly – Creator subscription platform featuring complex marketplace logic and secure Stripe Connect payouts. 💻 CORE EXPERT STACK → Frontend: React, Next.js, TypeScript, JavaScript, Tailwind CSS, ShadCN, Redux, Vue. (Specializing in highly responsive SaaS dashboards and pixel-perfect Figma-to-code migrations). → Backend: Node.js, NestJS, Express, Fastify, Python, FastAPI, REST APIs, GraphQL, tRPC, Socket IO. → Database & Caching: PostgreSQL, Supabase, MongoDB, MySQL, Redis, Prisma, Drizzle. → AI & Search: OpenAI & Claude APIs, LangChain, Pinecone, pgvector, RAG pipelines, Streaming Chat, AI Agents. → Payments & Billing: Shipped 7+ unique Stripe integrations (Checkout, Subscriptions, Connect, usage-based & credit-based billing), Razorpay, PayPal. → Cloud & DevOps: AWS (EC2, S3, Lambda, SQS, SES), Vercel, DigitalOcean, Cloudflare, GitHub Actions CI/CD. → Shopify Ecosystem: Remix, Polaris, GraphQL Admin API, App Bridge, BullMQ. 🤝 HOW I WORK WITH YOU → No Communication Gaps: You get a daily update, not silence for a week. I ask architectural questions early instead of guessing and rebuilding later. → Transparent Handovers: At delivery, you receive a clean codebase alongside a video walkthrough explaining exactly what was built and why. → Proactive Ownership: If an unexpected technical bottleneck arises or a timeline risks slipping, you will hear it from me first, along with two viable solutions. Let's build something that works in production, not just in a demo. Send me a brief summary of what you are building or where your current repo is stuck. I will tell you honestly whether I am the right fit and exactly what it will take to cross the finish line.
