About Sooraj S.
Backend Engineer passionate about building scalable, reliable systems that solve real problems.For the past 3+ years at Runo, I’ve designed reliable APIs implementing new features, designed and implemented WhatsApp Business API integrations from the ground up, enabling businesses to handle thousands of customer conversations seamlessly. I led a full MongoDB architecture migration (150K+ records,~40% faster queries), introduced serverless backend APIs, and migrated a large Vue 2 codebase to Vue 3.Before that, I’ve built everything from vaccination booking platforms and Telegram bots that scraped & delivered COVID data in real time, to face-recognition attendance systems on Raspberry Pi and even a custom TWRP device tree for my old Android device because I love solving problems end-to-end, whether it’s backend, full-stack, or low-level systems.Tech stack I work with daily:Node.js · TypeScript · Serverless Framework · MongoDB · PostgreSQL · AWS · Docker · Git · LinuxAlways excited to connect with founders, engineers, and anyone building the next big thing in communication, fintech, or open-source.Let’s talk systems, scalability, or just the next best thing.
