I take ownership of architecture, backend, frontend, and deployment to deliver a working product.

"Our backend is slowing down product delivery."

I clean up architecture, improve reliability, and make the system easier to evolve.

"Our APIs are messy or hard to scale."

I redesign APIs to be structured, reliable, and ready for growth.

"We are doing too much manually."

I automate workflows to reduce operational overhead and improve efficiency.

"We want to use AI but don't know how."

I identify real use cases and integrate AI features into existing systems.
