:02 / Story
Engineer by craft, researcher by curiosity. Five chapters from a gaming habit to building software for billions.
01 — The Spark
Technology was never the plan — gaming was. I began a computer science degree knowing almost nothing about programming, only that computers held tremendous power and I wanted to understand it. First-year C barely scratched the surface.
02 — First Build
In my second year I built a GUI-based 15 Puzzle game in Java — my first substantial creation from scratch. Programming stopped being lines of code and became a tool to bring ideas to life. I started betting on myself to conquer the steepest learning curves.
03 — Industry
Real-world code has to be clean, maintainable and scalable. I shipped backend services, optimized APIs and data-heavy queries, designed loosely coupled modular systems — and was promoted to Senior Software Engineer in a year and a half, mentoring new recruits along the way.
04 — The PhD
Three and a half years in, I left industry to pursue a PhD in usable security. As an HCI researcher I designed bias-free user studies and analyzed how people actually perceive security and privacy — work that earned a Best Paper Award at ACM CHI 2023.
05 — Now
I returned to industry carrying both skill sets: an engineer who ships and a researcher who asks why. At Meta I bring human-centered thinking to software built for billions of people.
:01 / Selected Work
P01
A fullstack web application to track job applications. A robust REST API built with Go manages applications, resumes and related resources, with resume storage in Azure Blob Storage. A modern React-Admin frontend provides an intuitive interface for tracking applications, managing resumes and organizing company interactions.
P02
The iconic game rebuilt in Unity around a sophisticated AI opponent with three difficulty levels — Normal, Hard, and Unbeatable. The AI leverages the Minimax algorithm with Alpha-Beta pruning to evaluate optimal moves and anticipate your strategy.
P03
A Windows application that brings the Taj Mahal to life in OpenGL — ambient lighting, white and blue point lights rotating a full 360°, dynamic shadows, and free keyboard camera navigation through the 3D scene.
P04
A client portal supporting FHIR healthcare interoperability standards — Practitioner, Patient and Observation resources with secure authentication against the Logica EHR sandbox and a resilient fallback to a local FHIR server.
