I’m a software engineer at AWS in Austin. I work on database networking, with previous experience in Lambda and an interest in tools that make day-to-day engineering a little easier.
I worked on networking workflows across 30+ AWS regions, including split-horizon DNS and validation for failover and network conversion.

The engineering challenge
The same endpoint needs to resolve correctly inside and outside a VPC, over both IPv4 and IPv6. I built validation across nine critical failover and conversion scenarios to address migration risk before launch. More than 200 enterprises adopted IPv6 in the first 60 days.
I worked on moving Lambda networking logic into a dedicated gRPC microservice, using parallel initialization to reduce cold-boot time.

The architectural decision
Networking logic was coupled to a larger service. Extracting it established a dedicated service boundary and allowed initialization to run in parallel. The result was $3M in annual infrastructure savings and cold boots 180 seconds faster.
I built an AI diagnostic tool that retrieves relevant context from 10,000+ technical documents, helping on-call engineers investigate incidents faster.

Why this approach
Engineers were spending time searching runbooks during incidents. Retrieval over the existing technical corpus puts relevant documentation closer to the question, reducing investigation time by 74%.
I’m working to shorten DNS propagation after an RDS Multi-AZ failover, so customers can reach the standby database sooner.

The reliability problem
A standby database can take over before DNS finishes propagating. That gap becomes downtime visible to customers. This work targets the propagation window, with a projected 70% reduction; this is a target, not a measured production result.

03 / A little context
A little about me
I grew up in Gaighat, Nepal, and came to Texas to study computer science at UT Arlington. Teaching other students was an early lesson in making complicated things understandable.
That instinct carries into my work today. Outside AWS, I explore iOS apps and AI tools — a chance to think about the person using the software as closely as the system running it.
