What I'm looking for

I’m looking for a staff/principal-level role building production ML/LLM infrastructure and AI systems—owning platform reliability, training/inference pipelines, and cost/reliability optimization—open to remote work and employer-supported relocation across major regions.

I’m an AI Systems Architect and ML Infrastructure Engineer with 20+ years in software and distributed systems, including 8+ years focused on ML, LLM, and AI systems in production.

I lead ML architecture and R&D end to end, combining technical strategy, hiring, roadmap ownership, and hands-on delivery. I built infrastructure from scratch for a globally distributed product across 8 regions, improving reliability, cost efficiency, and delivery speed.

My recent work includes LLM-based localization across 38 languages, generative AI systems, speech pipelines, and DRL/PPO prototypes. I’m most motivated by turning ambitious research ideas into scalable, production-grade systems with measurable impact.
