I'm an experienced AI Integration Architect focused on building scalable systems and automating workflows using the latest AI technologies. I don't just advise — I design the system and build it, end-to-end.

My work spans the full stack: from designing agentic frameworks and LLM pipelines to shipping production mobile apps. Notable projects include architecting a mobile sports wager tracking app with OCR capabilities and building data reliability layers for e-commerce systems.

Architecture + Execution
I design systems and build them end-to-end — no handoff gaps, no "that's the dev team's problem."
Operational Mindset
Strong focus on reliability and maintainability. Systems I build are meant to last and scale.
Clear Communication
Realistic timelines, honest assessments, no jargon for its own sake.

What clients say

"Shaleen has been great to work with. He's very thoughtful in how he approaches system design and took the time to clearly break down the architecture, tradeoffs, and roadmap for the project. He communicates well, explains complex technical concepts in a way that's easy to understand, and has been collaborative in aligning the build with my vision. I also appreciate his transparency around scope, timelines, and what's realistically needed to build a usable product. Overall, very professional and knowledgeable — I'd definitely recommend working with him."
