I lead a 10-engineer team building agentic AI that creates, personalizes, and translates content into 75+ languages — so it feels native in every market.
Five years at one company, five roles — from part-time intern on the translation core to leading the team behind an agentic AI platform.

Lead Software Engineer with 5+ years of hands-on expertise in full-stack development, distributed systems, and AI-driven solutions. I lead a 10-engineer team across system design, architecture, and code review for scalable, multilingual, and intelligent platforms serving enterprise customers.
Much of that work has been forward deployed — embedded directly with enterprise customers, turning a business problem into a running system. I have shipped alongside Mahindra Tractors on national campaigns reaching 350,000+ users, and onboarded 10+ enterprise customers onto our localization platform, owning the path from discovery through integration to production support.
01
Forward deployed delivery
Embedding with enterprise customers and shipping in their environment — scoping the real problem, integrating against their stack, and staying on it through production. Mahindra Tractors reached 350,000+ users; 10+ enterprise customers onboarded to our platform.
02
Applied AI
Shipping LLM features that hold up in production: agentic pipelines, RAG, speech and vision workflows, and QC agents that catch errors before release.
03
Systems & architecture
Designing distributed, event-driven services — microservices, queues, and cloud-native infrastructure that scale predictably and stay cheap to run.
04
Leading engineers
Running a 10-person team across system design, roadmap and code review — building the standards and review culture that keep quality high as we scale.
Joined as a part-time intern on the core translation modules and grew through five roles to lead the engineering team behind Vitra.ai's agentic AI platform.
