I'm Ahsen, a backend and platform engineer with a passion for resilient cloud systems, distributed architecture, and AI-first engineering. I've led multi-region failover efforts at AWS, built ML-driven development tools at VMware, and scaled global retail systems at Amazon. I currently conduct L6/L6+ technical interviews on interviewing.io, ranking in the top 20 interviewers on the platform, while exploring my next staff-level role. I enjoy working at the intersection of infrastructure, machine learning, and systems that serve millions, with a strong focus on reliability and clarity of design.

- Interview Signals – A live interviewer-side signal layer for mock interviews that reads the transcript and decides what’s worth interrupting for, at a quarter of a cent per interview.
- Queue Lab – A queue-benchmark harness running one fan-out workload across swappable backends (in-memory, Redis Pub/Sub, Kafka) to measure where messages are lost under slow consumers.
- GlossaryMe – Browser extension (Chrome, Firefox) that builds a personal, searchable technical glossary as you browse, using a configurable LLM backend (Anthropic, OpenAI, or local Ollama).
- Self-Driving RC Car – Behavioral cloning and real-time inference on Raspberry Pi.
- UI Code Generation using ML – [Hackathon] Tool to help teams create working UI prototypes
- Systems Experiments – Consistent hashing, Bloom filters, and a TinyLFU cache, each with a live interactive demo calling the real Java code directly.
