I build Python backend systems that hold up as they grow — designed properly from the start, so you're not rebuilding them a year later when traffic or features outpace the original setup. Most backend problems aren't really about writing code. They come from decisions made early that get expensive later. I focus on getting those right: how the system is structured, how the data is modeled, where the bottlenecks will show up, and what to build now versus what to leave room for. That judgment is what separates a system that scales from one that gets rewritten. What I do: Backend & APIs — FastAPI and Django REST, built for real traffic. Versioned, well-structured APIs with proper error handling, pagination, and idempotency — not just happy-path code. Architecture & scale — Multi-tenant SaaS systems with tenant isolation and role-based access. Structuring services and data flow so the system stays maintainable as it grows, not just on day one. Data layer — PostgreSQL schema design, indexing, query optimization, and migrations without downtime. Redis for caching and queues. Async & background work — Celery, event-driven workflows, webhook handling, and retries — the parts that need to keep working when external services don't. Taking it to production — I deploy what I build: Docker, AWS/GCP, CI/CD, and monitoring. I own the system end to end, so nothing gets handed over half-finished. When a system needs it, I also cover automation — n8n, Make, Zapier, or custom Python scripts — along with payment and third-party API integrations, so you get a complete build rather than parts to stitch together. Why hire me: 70+ completed projects, $80K+ earned on Upwork, 5,500+ hours, and consistent 5-star reviews. Recent work includes a recruitment platform handling 50K+ requests/day, a multi-service exam platform, and multi-tenant SaaS systems running in production. The code is clean, documented, and maintainable, and I deliver on time. If you need a senior engineer to build a backend that stays reliable long after launch — and to make the right calls while building it — message me. Tech: Python, FastAPI, Django, PostgreSQL, Redis, Celery, Docker, AWS, GCP

🚀 I build AI features and SaaS MVPs that ship on time. React and Next.js up front. Python, Node.js APIs on AWS. RAG with OpenAI and LangChain for answers grounded in your data. I'm Ishani Sharma, a senior full-stack engineer having 10+ years of professional experience. I take a product slice from design to production. TypeScript across the app. Clean UI. Fast API. Clear docs. You get maintainable code and a release you can put in front of users fast. For AI, I build retrieval pipelines with vector databases. I write prompt flows that stay stable. I add agent style automations for repeatable tasks. On the backend, I ship well structured Node.js services. I model data in PostgreSQL or MongoDB. I add authentication and authorization. I document each endpoint. Performance tuning where it matters. On AWS, I containerize with Docker. Kubernetes when orchestration helps. CI/CD so releases are predictable. That lowers release risk and keeps feedback loops tight. What I can help with: - AI features using OpenAI and LangChain with RAG grounded in your data - Next.js apps in TypeScript with responsive UI - REST APIs in Node.js on AWS. Auth included. Rate limits and logging wired - Data models in PostgreSQL or MongoDB with safe migrations and indexes - Vector database setup for chunking and embeddings. Fast retrieval - Docker and Kubernetes deployment. CI/CD that fits your release flow How I work: - Quick discovery. Scope and milestones within 48 hours, with estimates you can act on - Prototype or API spec within 48 to 72 hours - Weekly demos. Jira board stays current. You see progress daily - Clean Git history. Small PRs. Comments where it saves you time - Careful handover. README and runbooks. Short Looms if helpful I work IST hours with reliable overlap for US and EU teams. Fixed price or milestone based, whichever fits. If you want a grounded AI feature or a SaaS foundation that handles growth, let's scope it and ship the first usable release fast.
