    SaaS platform for photorealistic 3D model generation and product visuals for marketing:

    • Architected C++ asset processing pipelines for 3D model integration, handling mesh optimization, texture conversion, and format validation for production-scale photorealistic rendering workflows
    • Built Python integration layer between C++ asset processing pipelines and custom AI models (Hugging Face), including Blender API scripting for automated 3D asset generation
    • Systematic performance optimization across the full application stack: C++/Python rendering pipelines, and real-time OpenGL webviews
    • Integrated AI model outputs into the C++ asset processing system through custom bindings, enabling automated 3D asset creation
    • Worked in build infrastructure (CMake, QMake) and drove codebase modularity through systematic code reviews

    Fashion-tech SaaS for real-time 3D fabric simulation and texture digitalization on the browser. Split evenly between Python backend services and C++ HPC simulation engine.

    • Architected and delivered scalable backend microservices and async job processing using Python/Flask, PostgreSQL, and RabbitMQ, handling simulation requests with reliable queue-based workflows
    • Designed and implemented high-performance C++ HPC services powering real-time 3D simulation workloads, enabling browser-based fabric rendering with sub-second response times
    • Built the API layer that the frontend consumed directly, orchestrating work distribution across multiple backend microservices
    • Identified and resolved performance bottlenecks in distributed processing pipelines, including early-stage evaluation of GPU-accelerated computation (CUDA) for parallelizable simulation tasks
    • Built internal tooling, shared C++ libraries, and Docker-based CI/CD pipelines
    • Drove code quality through systematic refactoring, test coverage (Google Test, Pytest), and SOLID principles

    Industrial weighing systems manufacturer for retail environments. Built the entire software product for a commercial weighing system from scratch alongside one other engineer — from zero knowledge to full production deployment

    • Designed and owned the complete software stack on embedded Linux with C++ and Python: real-time weight acquisition from proprietary hardware, thermal/label printer integration, MariaDB database synchronization across 6-8 networked devices per store, and full graphical user interface
    • Implemented a custom TCP/IP protocol for real-time data synchronization between distributed embedded devices on local store networks
    • Built a MariaDB local replication network across all devices in each store, ensuring sales data consistency
    • Developed low-level Linux system services, hardware drivers, deployment automation, backup systems, and multi-language support for production embedded environments
    • Owned full product lifecycle — requirements, architecture decisions, OS selection, prototyping, implementation, testing, field deployment, and long-term maintenance across multiple hardware revisions
