About Me

Hey there 👋 I'm Arun, a Full-stack AI Engineer with over 5 years of experience building robust, scalable applications across the enterprise ecosystem. I specialize in creating impactful user experiences using the MERN stack, and I'm currently diving deep into the world of AI, microservices, and cloud-native architectures at Telus Digital.

Right now, I'm working on integrating gRPC and GCP Pub/Sub in our production-grade micro frontends to enable high-performance, event-driven systems. My work often bridges the gap between frontend finesse and backend resilience—building micro-frontend starter kits, designing infra flows to fetch secrets securely on GCP, and rolling out reusable component libraries used by multiple teams.

In the AI space, I tinker with MCP servers, prompt engineering, and have actively contributed to building AI-powered tools that enhance productivity across our digital platform. My team snagged 3rd place in a Telus-wide AI Hackathon, which was an amazing ride!

When I'm not coding, you'll usually find me jamming on my guitar, gaming, or nerding out over new tech. I love pushing the limits of what's possible—whether that's building smarter systems, exploring new dev workflows, or helping fellow engineers level up.

If you're into clean code, cool projects, and conversations about tech (or music and Anime!), we'll probably get along just fine :)
