About

Backend Engineer | 3+ YOE | Scalable Systems | Cloud-Native Development | AI Integration I'm a backend engineer with 3+ years of experience building scalable, event-driven microservices and cloud-based systems using Node.js, Python, TypeScript, AWS, Kafka, and Kubernetes. I specialize in designing robust backend architectures for performance-critical applications with a strong focus on clean code, reliability, and DevOps best practices. My recent work includes: - Developing intelligent AI-powered calling agents using Twilio and GPT-4 with LangChain and Pinecone - Architecting secure authentication systems with 2FA & RBAC - Building cloud-native pipelines on AWS (ECS Fargate, Lambda, S3, API Gateway) - Deploying microservices with Docker, Kubernetes, and GitHub Actions CI/CD I’m proficient in REST, GraphQL, gRPC, Redis caching, and PostgreSQL. I enjoy solving real-world problems, automating workflows, and contributing to high-impact tech products in fintech, SaaS, or AI domains. Currently working on advanced backend projects involving AI agents and vector databases, while actively seeking new remote/backend opportunities in product-driven companies
