Joined Cautio as the first backend eng, did everything that was required i.e. from handling infra (AWS) and coding frontend (Next.js), making automations (using LLMs) to writing backend and designing systems (video streaming, complex service-to-IoT-device communications) Some of my contributions are: - Designed the core schema of the Cautio OS and built the core API microservice, which was exposed via API Gateway behind private ALBs from scratch, that caters to 45+ clients all over India. - Top contributor of the backend repositories, also contributed to the frontend side of the Cautio OS built in NextJS. - Designed and built 5+ systems that deliver various types of data, analytics, and media via low-latency APIs. - Worked on several microservices that deal with processing binaries from IoT devices and sub-200ms video streaming using FFmpeg, MPEG-TS, and WebSockets. - Deployed distributed systems on AWS ECS using Service Connect, VPC, and private ALBs, achieving 40% lower service latency and improved security. - Re-architected cloud infrastructure, reducing AWS costs by 40%. - Created a custom load testing tool simulating 10k concurrent IoT devices for benchmarking. - Automated repetitive OPs team tasks using Jenkins, custom CLI, and cron jobs. - Helped many B2B clients to integrate Cautio APIs with their custom software solutions. Tech stack: nodejs, typescript, kafka, AWS, Jenkins, Postgresql, MongoDB
