Technical Lead · Senior Unity Engineer · XR & Real-Time Simulation

Software engineer with 10 years of professional Unity and C# experience, focused on performance, rendering and simulation on standalone hardware (Meta Quest, Pico). I build the systems other developers and designers build on: interaction frameworks, scripting tools, shaders and editor tooling. I shipped a commercial flight simulator from my own idea to a Steam release and acquisition, and I have grown from student intern to technical lead at the same company.

Senior Software Engineer · Nov 2022 – Dec 2025
- Led multiple projects in parallel: architecture, task breakdown, workload distribution and delivery quality
- Built a modular interaction library that lets new training scenarios be assembled from reusable parts, cutting time-to-delivery
- Designed a custom visual scripting framework (custom Units and Event Units) inspired by Rockstar's mission scripting, so designers and non-programmers can author scenario logic without code changes
- Worked directly with clients to define interaction requirements and keep simulations accurate and intuitive
- Built Unity editor tools and introduced version control, testing and CI practices across teams

Medior Software Engineer · Oct 2019 – Oct 2022
- Designed and developed VR training solutions for the oil & gas industry
- Owned prototyping, architecture definition and scenario building inside real CAD environments
- Supported backend work: database design, server-side systems and cloud content delivery

Software Engineer · Oct 2018 – Oct 2019
- Took ownership of VR/AR application development and deployment end to end
- Built CMS integration and remote content updates; handled on-site installations

Student Software Engineer · Oct 2016 – Oct 2018
