Experience
Eddy​ ​ ​ ​ ​ ​ ​ ​ ​ 02/2025 – 12/2025
Developed and drove end-to-end Unity-side delivery of a PC-based shooting range simulator used in classroom
and training environments, combining hands-on development with technical coordination across multiple teams.
Designed deployment tooling, including a custom launcher and CI/CD pipeline, streamlining updates and
configuration management across installations. Improved performance, rendering and overall stability on low-end
PCs, reduced build size by 25-30%, enabling deployment across 25+ installations and lowering critical runtime

Panthera​ ​ ​ ​ ​ ​ ​ 01/2023 – 02/2025
Owned key gameplay systems, player-facing features, LiveOps content, player data and progression systems for
a mobile shooter (BoxHead), from early development through release and LiveOps support. Provided technical
leadership for feature delivery, coordinating implementation across developers and aligning solutions with design,
art and QA. Through LiveOps iterations and progression tuning achieved a 12-15% uplift in D1/D7 retention and
contributed to 10-12% ARPU/LTV growth. Improved product stability via performance, memory and build footprint
optimizations, reducing crash rate and ANRs by 30-35%. After stabilizing BoxHead, contributed to early
development of a second title (Soul Huntress, RPG). Projects reached a combined 1.5M+ installs on Google Play

Deep Space Software​ ​ ​ ​ ​ ​ 10/2020 – 01/2023
Worked on an outsourced PC RTS project during early and mid-production stages prior to public release. Was
responsible for core gameplay (including unit and opponent AI), multiplayer and client-side systems, working
directly with the client, contributing to task breakdown, technical decision-making and code reviews. Achieved
stable large-scale RTS battles with 1500 active units at 50-60 FPS, reduced CPU bottlenecks by 40-50%, cut
multiplayer desync issues by 30-40% and reduced multiplayer traffic usage by ~30%, improving overall match
