SOFTWARE ENGINEER · FULL-STACK & APPLIED AI

From a messy process
to a working system.

I’m Kevin. I build web applications, backend systems and practical AI tools — connecting the pieces from architecture to deployment.

01 / SELECTED WORK

The systems behind the interface.

A business platform built end to end, alongside focused explorations in AI and machine learning.

ENGINEERING SHOWCASE

AI automations, with evals.

Invoice extraction and lead intake with structured validation and a field-level evaluation harness.

  • TypeScript
  • Zod
  • OpenRouter

Live evaluation: 68 synthetic cases recorded, including five output failures. Published results include the failure analysis.

ENGINEERING SHOWCASE

Inference, off the request path.

An ML serving template that separates a FastAPI gateway from ONNX model workers through a Redis queue.

  • Python
  • FastAPI
  • Redis
  • ONNX

Locally verified with real model inference and worker-interruption recovery. Recovery tests and benchmark evidence are published.

02 / EXPERIENCE

Built across the stack. Grounded in the details.

My work spans backend development, full-stack delivery, ML deployment and hands-on evaluation of language models.
