I have worked on production-grade systems where reliability, performance, and clean architecture were important. My experience includes designing subscription billing flows, building secure APIs, and improving response times through indexing, query optimization, and modular backend design. I enjoy solving complex engineering problems and turning them into practical, maintainable solutions. I have strong hands-on experience with microservices, WebSocket-based features, JWT authentication, RBAC, rate limiting, and asynchronous processing pipelines. I also work with AI-enabled backend workflows, including RAG pipelines, vector search, embeddings, and LLM API integrations. In one of my projects, I built a document intelligence API with pgvector, Redis, BullMQ, Docker, and AWS deployment automation. Alongside backend development, I have a strong problem-solving foundation with 1000+ DSA problems solved and competitive programming achievements in Google Code Jam, Google Kick Start, and Meta Hacker Cup. I am looking for opportunities where I can contribute to backend engineering, system design, and scalable product development while continuing to grow in high-impact technical environments. ## Skills ### [Python](https://jobicy.com/talent/python.md)[AWS](https://jobicy.com/talent/aws.md)[JavaScript](https://jobicy.com/talent/javascript.md)[Java](https://jobicy.com/talent/java.md)[Docker](https://jobicy.com/talent/docker.md)[CI CD](https://jobicy.com/talent/ci-cd.md)[C++](https://jobicy.com/talent/c-plus-plus.md)[PostgreSQL](https://jobicy.com/talent/postgresql.md)[MySQL](https://jobicy.com/talent/mysql.md)[Kafka](https://jobicy.com/talent/kafka.md)[Microservices](https://jobicy.com/talent/microservices.md)[MongoDB](https://jobicy.com/talent/mongodb.md)[Distributed Systems](https://jobicy.com/talent/distributed-systems.md)[Redis](https://jobicy.com/talent/redis.md)[REST APIs](https://jobicy.com/talent/rest-apis.md)[NoSQL](https://jobicy.com/talent/nosql.md)[GitHub Actions](https://jobicy.com/talent/github-actions.md)[System Design](https://jobicy.com/talent/system-design.md)[OOP](https://jobicy.com/talent/oop.md)[Firebase](https://jobicy.com/talent/firebase.md)[API Gateway](https://jobicy.com/talent/api-gateway.md)[Nginx](https://jobicy.com/talent/nginx.md)[Prisma](https://jobicy.com/talent/prisma.md)[JWT](https://jobicy.com/talent/jwt.md)[RBAC](https://jobicy.com/talent/rbac.md)[Vector Search](https://jobicy.com/talent/vector-search.md)[BullMQ](https://jobicy.com/talent/bullmq.md)[Pgvector](https://jobicy.com/talent/pgvector.md)[Razorpay](https://jobicy.com/talent/razorpay.md)[RAG](https://jobicy.com/talent/rag.md) ## Tech Stack & Tools ### Application Hosting [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/firebase/firebase-original.svg) Firebase](https://jobicy.com/talent?tool=firebase.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/nginx/nginx-original.svg) Nginx](https://jobicy.com/talent?tool=nginx.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/redis/redis-original.svg) Redis](https://jobicy.com/talent?tool=redis.md) ### Data Stores [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/mongodb/mongodb-original.svg) MongoDB](https://jobicy.com/talent?tool=mongodb.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/mysql/mysql-original.svg) MySQL](https://jobicy.com/talent?tool=mysql.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/postgresql/postgresql-original.svg) PostgreSQL](https://jobicy.com/talent?tool=postgresql.md) ### Development [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/docker/docker-original.svg) Docker](https://jobicy.com/talent?tool=docker.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/git/git-original.svg) Git](https://jobicy.com/talent?tool=git.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/leetcode/leetcode-original.svg) LeetCode](https://jobicy.com/talent?tool=leetcode.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/prisma/prisma-original.svg) Prisma](https://jobicy.com/talent?tool=prisma.md) ## Experience Backend Developer @ BidPoint Platform Pvt.
