Ever run into a system design roadblock, struggled with scaling challenges, or wondered how to make the right architectural trade-offs? That’s where I come in. With 7+ years of experience as a software engineer, I’ve built and scaled distributed systems that support tens of thousands of concurrent users and maintain reliability across multiple data centers. Currently, I’m an SDE III at Flipkart, where I focus on high-availability platforms, real-time messaging, and at-least-once processing guarantees.

Here’s what you’ll get when you bring your toughest questions my way:

Actionable Guidance: Practical advice rooted in designing and running production-grade systems at scale.

Clear Trade-Offs: Insights on reliability, performance, and cost, helping you make informed architectural decisions.

End-to-End Expertise: From low-level design (LLD) to high-level design (HLD), distributed messaging, and cloud-native systems.

Mentorship Approach: Empathetic, constructive feedback to help you level up as an engineer.

I’ve not only delivered complex projects at scale but also contributed to open-source (Apache Pulsar) and mentored multiple engineers within my teams. Whether you’re preparing for an interview, debugging a tricky distributed system, or just looking for a second opinion on a design, I’ll help you cut through the noise and find clarity.
