Senior Unity Developer with over 10 years of experience in the Unity ecosystem, developing high-performance mobile games, applications, and scalable systems used by millions of users globally.
Expertise in C# and Unity3D, with a strong focus on systems architecture, performance optimization (CPU/GPU/Memory), and delivering stable products across mobile, gamified, and XR environments. Proven track record of collaborating with product, design, and engineering teams to translate complex requirements into efficient, user-centric solutions.
Throughout my career, I have led and implemented solutions with direct impact on scale and efficiency, including:
- Global Expansion: Built a localization system for 70+ languages, supporting worldwide product growth.
- Performance Optimization: Improved mobile performance by up to 70%, specifically for low-end devices.
- Workflow Efficiency: Reduced prototyping time by 50% through modular architecture and workflow improvements.
- Market Success: Contributed to products exceeding 10 million downloads in highly competitive markets.
Technical Core: Unity Architecture, Mobile Optimization, XR (AR/VR), UI/UX Implementation, APIs, Design Patterns (SOLID), and engineering best practices focused on long-term scalability and maintainability.
I am currently interested in Senior Unity / Game Development roles, particularly within product-driven companies, mobile gaming, EdTech, or interactive experiences where performance, technical quality, and large-scale impact are priorities.
Always open to connecting and discussing Unity, mobile performance, game systems, and digital products.
