Namrata
I am a Java and Angular Developer with over 2 years of experience designing and developing robust, scalable, and maintainable enterprise applications. My core expertise lies in Java, Spring Boot, and Angular, where I build clean backend services and responsive frontend applications that are easy to extend and maintain. I have worked extensively on RESTful APIs, microservices-based systems, and full-stack applications used by thousands of users in production environments. I have strong experience translating business requirements into technical solutions, designing efficient database schemas, and optimizing application performance. I have worked closely with product owners, business analysts, and development teams to deliver high-quality software on time. I am comfortable taking ownership of features end-to-end — from requirement analysis and system design to development, testing, and support. I focus on writing clean, well-structured code and building solutions that are reliable and scalable. Clients value my clear communication, structured problem-solving approach, and ability to work independently on complex Java and Angular projects.

🚀 AI Systems & Backend Engineer | Production Ready LLM Solutions I help companies build AI systems that actually work in production — not just demos. Most AI projects fail after deployment due to unreliable outputs, scaling issues, or rising costs. My focus is solving exactly that: building robust, scalable, and cost-efficient AI systems that perform reliably in real-world environments. What I Do ✔ Design and build production-grade LLM systems (OpenAI, Anthropic, RAG pipelines)✔ Develop AI agents and workflows with retries, idempotency, and auditability✔ Improve AI reliability using schema validation, tool contracts, and fallback logic ✔ Optimize performance with hybrid search, caching, and smart chunking ✔ Build scalable backend systems and APIs (FastAPI, Node.js, distributed systems)✔ Ensure data consistency and fault tolerance in high-concurrency environments What Makes Me Different Most developers can connect to an AI API. Few can make it reliable. I specialize in: Preventing duplicate executions, race conditions, and partial failures Designing systems that gracefully handle errors instead of breaking Reducing API costs and rate-limit issues through smart architecture Turning unstable AI outputs into predictable, production-ready systems Proven Experience Built and operated LLM systems used in customer support, sales, and internal tools Eliminated backend inconsistencies in high-scale systems handling real users Delivered MVPs that successfully scaled into production environments Integrated AI into existing systems without costly rewrites Example Projects 🔹 AI Customer Support SystemStructured LLM pipelines with real integrations (CRM, ticketing systems) 🔹 AI Booking AgentReliable transaction handling with retries, rollback strategies, and rate-limit control Tech Stack Python, Rust, TypeScriptFastAPI, Node.js, NestJSPostgreSQL, Redis, ElasticsearchLangChain, LlamaIndex, OpenAI, AnthropicDocker, CI/CD, Cloud Deployment Let's Work Together If you're looking for: A system that won't break among real users AI that produces consistent, usable results A backend that scales without surprises Send me a message with your project details — I'll help you build it the right way from the start.
