What I'm looking for

I’m looking to contribute in control/engineering delivery and backend development, working with Agile teams. I want ownership of troubleshooting and integrations, plus room to grow with AI tooling, clean documentation, and strong mentorship.

I’m a Mechanical Engineering graduate and certified project management professional with experience supporting industrial systems through control engineering work and hands-on technical troubleshooting. In my roles, I interpret complex Piping & Instrumentation Diagrams (P&IDs) to support valve selection and system troubleshooting, and I assist with safety checks and maintenance for commercial gas systems.

I also build and optimize server-side solutions through backend web development (Python), secure RESTful API integration, and relational database management. Alongside this, I work with AI support and prompt engineering—designing and iterating context-aware prompts for Large Language Models (LLMs)—while leading administrative operations and coordinating documentation using Agile and traditional project management practices.
