Svetlozar Valchev

Co-founded and architected SPARQ, a cross-platform C++ game engine spanning rendering, asset pipelines, native and browser runtimes, TypeScript tooling, multiplayer replication, and cloud delivery. I built major parts of the asset path, implemented replicated ECS state and V8-powered scripting with hot reload, and developed an authenticated native MCP subsystem that lets AI agents inspect and operate projects, assets, runtime state, screenshots, and networking.

Designed and built Plug & Rev, an engine-sound authoring system that turns engine definitions and structured feedback into deterministic audio auditions and portable .revengine packages. I developed the C++ simulation and audio core, WebAssembly runtime, browser-based studio, diagnostic telemetry, AI-assisted authoring loop, and AWS delivery platform. The exported runtime can be driven by RPM, throttle, and load in web, Unity, and vehicle-physics integrations without embedding the source simulator.

Built the product and engine integrations around several applied AI systems. I productized LoRA-based eCommerce model generation through job, asset, product, billing, and application workflows; built Unity editor tooling for text-to-3D, image-to-3D, texturing, and asset libraries; contributed to the Unreal integration; and helped integrate a custom terrain-generation model into Unreal heightmap and material workflows. My focus was on turning model capabilities into usable production tools.

Built and maintained healthcare software covering nursing and patient management, bed and ward allocation, patient statistics, device and API integration, operational dashboards, FHIR-based interoperability, and browser-based clinical visualization. My work covered product interfaces, back-end services, data models, third-party integrations, and production maintenance.

Built a visual template editor and server-side Canvas and FFmpeg rendering pipeline for personalized digital athlete cards. I also delivered browser-based 3D previews and AWS rendering infrastructure using Lambda, S3, queues, and automated asset delivery. The work covered product UI, back-end rendering, asynchronous processing, cloud operations, and production support.

Architected a high-performance IPTV interface and a custom memory-conscious MVVM framework for resource-constrained set-top boxes. I led multi-client white-label delivery, built automated interface testing infrastructure, and repeatedly profiled and rewrote critical paths to keep the product responsive across devices with severe CPU and memory constraints.

Built UI foundations and core AngularJS systems for BeamNG.drive during its early development. I helped define the UI technology and direction, implemented performance-conscious interfaces for an ambitious real-time vehicle simulation, and worked on usability, accessibility, and integration with the game runtime. I am credited in the released game.

Developed major systems for Traffic Manager, one of the largest Cities: Skylines mods, adding traffic lights, priority signs, lane restrictions, and AI traffic controls. I worked in C# and Unity on the game simulation systems. The open-source mod had around 100,000 subscribers during my involvement and became a long-running community project.
