About Naveen Singh

Hey there! Senior Backend Dev & Data Engineering Lead who turns complex system design diagrams into production-ready nightmares (kidding, they actually work pretty well). What I Actually Do: Architect & build production-grade SAAS platforms from ground up (Authentication Payments Analytics ) Design distributed data pipelines that handle 15M+ monthly records (and don't break at 3 AM) Make databases go (reduced query latency from 20s → 500ms) Turn ML/AI from buzzwords into business value (built systems that actually work in production) Tech I Live By: Backend & APIs: Node.js/NestJS, Express, Flask, REST, gRPC Data Engineering: Apache Kafka, Spark, Beam, Flink Databases: ClickHouse, PostgreSQL, MongoDB, Cassandra, MS SQL Cloud & DevOps: GCP, AWS, Docker, K8s, CI/CD pipelines that don't fail on Fridays AI/ML Stack: LangChain, RAG, Vector DBs, OpenAI GPT-4, Claude, LLAMA, Mistral Message Queues: Kafka (yes, again), Redis, RabbitMQ Monitoring: ELK Stack, Prometheus, Grafana (because logs are life) Recent Wins: Built SAAS platforms that actually make money (with all the boring-but-critical stuff like auth, payments, and analytics working smoothly) Engineered a product categorization system processing products/second with 95% accuracy Reduced data processing time from 30 days to 3 (because ain't nobody got time for that) Cut operational costs by 80% through smart LLM implementations (management loved this one) Current Tech Explorations: When I'm not optimizing production systems, you'll find me diving into Flutter/Dart for app development, exploring Web3 possibilities, or diving deep into cybersecurity rabbit holes. When not coding: Probably watching anime, debugging production issues, or explaining why we should switch to TypeScript (again) Open to conversations about: System design that survives production Making databases go faster Why PostgreSQL is superior (fight me) Your favorite anime recommendations That new tech stack you're excited about (I'm always up for learning something new!) Let's connect if you're into building cool stuff that scales! If it's tech, I'm interested!
