The Architect

Engineering for
Scale & Security.

Hey there! I'm Kumar Dhananjaya, an Associate Software Engineer passionate about building scalable, high-concurrency applications and secure cloud-native experiences. With expertise in the MERN stack, React Native, and DevSecOps, I focus on turning complex technical challenges into robust, production-ready solutions.

I've architected high-availability platforms on Azure, engineered distributed systems capable of handling 100k+ RPS, and implemented comprehensive Zero-Trust security pipelines. I'm deeply interested in distributed systems, CRDTs for real-time collaboration, and the intersection of DevOps and Security.

When I'm not architecting systems, you'll find me exploring new tech stacks (currently delving into Golang and NestJS), participating in national-level hackathons (2nd prize at HPE SWARM-IT!), or sharing my journey and insights through my technical blog at kdexplorations.hashnode.dev.

The Journey

Building the Future.

Jul 2024 – Present

Associate Software Engineer

Examic EdTech / Mysuru, India

  • Architected a low-latency Online Assessment Platform on Azure, leveraging WebSockets to achieve <150ms real-time proctoring and state synchronization.
  • Engineered an enterprise-grade internal CMS and e-commerce engine, automating exam packaging and payment workflows to reduce operational overhead.
  • Pioneered a hardware-to-cloud bridge in React Native for 'IRIS' IoT, implementing secure BLE pairing and real-time device monitoring.
  • Hardened infrastructure security and availability by implementing NGINX reverse proxies and Zero-Downtime (ZDT) deployment strategies.
  • Refactored MongoDB schemas and API logic to support 1000+ concurrent users, resulting in a 25% reduction in end-to-end query latency.
