What I'm looking for

I seek a role where I can lead backend architecture, mentor engineers, improve system resilience, and deliver measurable performance and reliability gains.

I am a senior software engineer with a strong backend foundation and a passion for building high-performing teams and resilient systems. I lead engineering efforts end-to-end—from architecture to delivery—driving technical excellence, ownership, quality, and continuous improvement.

My recent work includes integrating GPT into automated evaluation, migrating embedded caches to shared distributed clusters, and deploying ML microservices for spam and fraud detection that reduced false positives by 11%. I have built scalable ETL pipelines on Spark/Databricks, designed dockerized fine-tuning pipelines for custom TTS voices, and improved in-memory caching with measurable production impact.
