15 years building for the web, with 4.9/5.0 across 250+ clients. Founder-led engineering. You work directly with me, not a project manager or a junior dev. I run my own AI-powered productivity SaaS (SelfManager.ai), so when you bring me an AI integration project, you're hiring someone who actually ships and operates production AI in his own product, not someone reading the OpenAI docs for the first time. What I do best: - Adding AI features to existing web apps without breaking what already works - Workflow automations that connect your stack to LLMs, APIs, and databases - Full-stack development on Angular, Firebase, Shopify, Webflow, Squarespace, and WordPress Whether you need an MVP built from scratch, an existing app extended, or AI added to a product you already run, I handle it end to end. Known for high-quality work, fast replies, and clear communication throughout the project. Past work includes: - SelfManager.ai - SafeOpt & AddShoppers (now Minty) - Fly Jet BLAK - Katherine Hooker London - Parley - Ayana Resorts - Oppo Brothers - ONE65 San Francisco - Shot Of Joy - Spare Space - 3D People UK - Mirabello Interiors - The Garden Gates Tell me what you're building. I'll send back a mini plan, scope, and quote within 24h. If I'm not the right fit, I'll say so.

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.

I'm a Java developer and full stack developer with 5+ years building backend systems, REST APIs, microservices, and full stack web applications. As a full stack developer, I work end-to-end with Java and Spring Boot on the backend, React and Angular on the frontend, but backend engineering is where I spend most of my time and add the most value. On the backend, my core stack is Java, Spring Boot, and Spring Framework, with REST APIs, Hibernate/JPA, PostgreSQL, MySQL, MongoDB, and SQL for persistence. As a backend developer, I've designed 120+ REST APIs and built 10+ microservice architectures from the ground up, for systems serving anywhere from 10K to 500K+ users depending on project scale. I've shipped 35+ production projects as a full stack developer and Java developer, across fintech, logistics, telecommunications, retail, SaaS, healthcare, and enterprise. For infrastructure, I work across AWS, GCP, and Azure, and I'm comfortable with Docker, Kubernetes, and CI/CD pipelines to keep backend systems reliable in production as part of full stack delivery. Performance is something I take seriously as a backend developer: on several engagements, I've cut API response times by up to 60% and improved overall system performance by 40%+ through targeted refactoring and architectural improvements, rather than costly rewrites. I've also worked extensively with enterprise-level database schemas, writing and optimising complex SQL queries, indexing strategies, and data models across tables with 100K+ records. The production systems I've maintained as a Java backend developer have consistently held 99.9% uptime, that doesn't happen by accident. It comes from solid monitoring, thoughtful deployment practices, and knowing where the failure points are before they become incidents. When a project calls for it, I also write Python, PHP, and Node.js, and handle frontend work in React or Angular including JavaScript for client-side logic, but as a full stack developer, my strongest work is where backend architecture meets a clean frontend implementation My clients get clear communication, fast responses, and code that's actually maintainable six months later. I'm business-focused and I care whether the thing solves your problem, not just whether it compiles. As one client put it: he doesn't just write code, he thinks about why we need it in the first place. Beyond hands-on Java development, I've led teams, mentored junior developers, and run cross-functional projects where the technical and human sides both needed managing. I'm open to long-term collaborations and challenging projects involving Java, Spring Boot, full stack development, backend architecture, React, Angular, cloud systems, and microservices. Need a full stack developer, Java developer, or backend developer who ships clean code and tells you when you're building the wrong thing? That's the conversation worth having. Drop me a message.
