Pravachan

Software Engineer

Software EngineerMar 2025 – June 2026 · 9 mosRemote, India

Built and scaled a cross-platform mobile platform end-to-end — from architecture to production deployment — serving a spiritual content platform delivering live and on-demand content across India.

Built a React Native + Node.js mobile app serving 500+ active users, with a centralised admin dashboard maintaining 99%+ uptime across Android and iOS.
Reduced API response time by ~35% by implementing Redis caching and connection pooling on high-traffic endpoints.
Designed a Docker microservices architecture (auth, media, payments, notifications, analytics) with PostgreSQL, MongoDB and Redis; automated deployments via GitHub Actions CI/CD, cutting release time by over 80%.
Built Razorpay subscription APIs covering the full payment lifecycle — create, renew, cancel and webhook failure recovery; integrated Cloudflare CDN for global content delivery.

A little bit about me

Who I am and what I do.

WHO I AM

I'm Abhinav Vardhan, a backend and cloud engineer based in Hyderabad, India. I love building the systems that quietly power great products — reliable, scalable, and clean.

WHAT I DO

I specialise in backend systems, cloud-native infrastructure, and developer tooling. From designing RESTful APIs and microservices to automating CI/CD pipelines and deploying on AWS — I care deeply about performance, reliability, and clean architecture.

WHAT I'VE BUILT

I've shipped a production mobile platform serving 2,000+ active users at Pravachan, led a 400-person engineering club, and built Web3 projects at ETHGlobal hackathons. Every project is a chance to solve a hard problem well.
