Startups, enterprises and public-sector organizations bring me in when the product needs strong technical decisions, not just execution - production AI systems, SaaS platforms and fintech, from architecture to live deployment. Most engagements start with a fixed-price design phase that defines architecture, scope and roadmap, then convert into fixed milestones, so delivery stays structured and budget predictable. Rate $125-150/hr depending on complexity; most work is delivered as fixed-price milestones. What I specialise in: AI/LLM systems - RAG pipelines, multi-tenant AI assistants, agent orchestration, Claude/OpenAI integrations, structured outputs, eval pipelines.

Best fit when the product needs architectural ownership - not a fit for quick fixes or one-off tasks.

Most Node.js backends don't fail at launch. They fail six months later — when traffic doubles, queries slow to a crawl, and the architecture nobody questioned becomes everyone's problem. I build SaaS backends that don't do that. I'm Neha, a Node.js Backend Developer and Backend Systems Architect with 9+ years shipping production systems that hold up under real load — across fintech, healthcare, e-commerce, real estate, travel, and e-learning. I've taken products from pre-launch to 50M+ requests/month and 100M+ rows without rewrites. The pattern I'm hired to prevent: a PostgreSQL table that's fine at 10K rows and a problem at 10M, an API that drops connections at 500 concurrent requests, a Stripe integration that breaks the moment a card fails mid-subscription. These aren't edge cases — they're the normal lifecycle of a growing product, and the backend has to be built for them from day one. What I do: • Scalable REST APIs & microservices in NestJS, Express.js, and TypeScript — designed around your actual load and data patterns, type-safe, and readable for the next dev. • AWS production infrastructure — EC2, ECS, Lambda, RDS (PostgreSQL with proper pooling, backup, failover), and API Gateway, plus repeatable CI/CD on GitHub Actions and GitLab. • Database performance — PostgreSQL and MongoDB schema design, indexing, and query optimization on live systems with no downtime. (Recently cut a client's slowest endpoint from 4.2s to 180ms — a single N+1 query buried in a dashboard load — without any downtime on the live system.) • Payments & integrations — Stripe, RevenueCat, Razorpay, and Meta APIs done properly: subscriptions, trials, upgrades, failed-payment recovery, and reliable webhooks. Before I touch code I map the full backend — data models, API contracts, third-party dependencies, caching strategy, and the two or three places likely to break under load. That conversation upfront saves weeks of reactive fixes later. If you've got a backend that's slowing down, a scaling deadline coming, or a payment flow that's drifting out of sync — send me the specific pain point and I'll tell you how I'd approach it.
