JUL 2024 - PRESENTCURRENT

AI / ML Engineer

AquilaX.AI · London

Building AI-powered application security tools, from model development to production delivery.

  • Engineered SecuriTron AI using 300M+ open-source projects, eight SAST scanners, and custom Qwen3 and LLaMA models: 96% report accuracy and 20% fewer false positives.
  • Released an Apache 2.0 ML model with sub-100 ms inference for real-time vulnerability triage.
  • Built FastAPI services and Streamlit/React interfaces supporting 100+ concurrent users.
  • Integrated GitHub Actions, Docker Compose, MLflow, and Weights & Biases, accelerating release cycles by 30%.

04 / THE PERSON BEHIND THE CODE

A curious mind.
A builder
at heart.

I’m Pachaiappan, an AI engineer and developer. I connect machine learning with software engineering to turn complex problems into things people can actually use.

Pachaiappan.Always a learner.

Behind every build.

A problem to understand. An idea to explore.

01Understand first.

I start by understanding the problem and what would make a solution useful. The goal is software that solves practical problems.

02Stay curious.

My interests span generative AI, computer vision, natural language processing, algorithms, and visualization. Experimenting with a model is part of the process.

03Make it useful.

I enjoy shaping experiments into something people can use - connecting machine learning, application development, and production delivery.
