Built a production-grade RAG chatbot at Visa using Python and OpenAI. Transformed JIRA tickets and SDK documentation into an automated technical support system.

Python OpenAI Redis Vector-DB
Autonomous Systems

Custom Agent Frameworks

Building multi-agent systems that handle real enterprise workflows. Tool-use, self-correction, long-term memory -- the pieces that make agents actually useful in production.

LangChain Multi-Agent Reasoning

Engineering Core

Scale & Performance Engineering

Built mobile systems at scale for du, Lebara, and Huawei (millions of users, 99.9% stability targets). Now bringing that same obsession with reliability to AI products that need to work in production, not just in demos.

Android/iOS Scalability Performance CI/CD

Integrations & SDK Architecture

Built enterprise SDKs at Visa (200M+ devices) and secure messaging wrappers at Katim (E2EE). The kind of work where you're writing cross-platform C++ bindings one day and wiring them into AI pipelines the next.
