Project history
SaaS platform for photorealistic 3D model generation and product visualization.
- Architected C++ asset processing pipelines for 3D model integration, handling mesh optimization, texture conversion, and format validation for production-scale photorealistic rendering workflows
- Led systematic performance optimization across the full application stack: C++/Qt desktop tools, backend rendering pipelines, and real-time OpenGL webviews — profiling, identifying bottlenecks, and delivering measurable throughput improvements
- Integrated AI-generated content into the C++ asset processing system, enabling automated 3D asset creation and reducing manual artist intervention in the production pipeline
- Enhanced in-house artist tooling (C++/Qt), streamlining asset ingestion and scene-building workflows
- Modernized build infrastructure (CMake, QMake) and drove codebase modularity through systematic code reviews
100% remote - Paris, France
Fashion-tech SaaS for real-time 3D fabric simulation and texture digitalization on the browser.
- Designed and implemented high-performance C++ HPC services powering real-time 3D simulation workloads, enabling browser-based fabric rendering with production-level fidelity and sub-second response times
- Identified and resolved performance bottlenecks in distributed processing pipelines, including early-stage evaluation of GPU-accelerated computation (CUDA) for parallelizable simulation tasks
- Delivered scalable backend microservices and asynchronous job processing using Python/Flask, PostgreSQL, and RabbitMQ, supporting high-concurrency simulation requests
- Built internal tooling, shared C++ libraries, and Docker-based CI/CD pipelines that standardized development workflows and reduced build/deploy friction across the engineering team
- Drove code quality through systematic refactoring, comprehensive test coverage (Google Test, Pytest), and enforcement of SOLID design principles across the C++ and Python codebases
100% remote - NY, US
Industrial weighing systems manufacturer for retail environments.
- Designed and built from scratch the complete software stack for a commercial weighing system on embedded Linux: real-time weight acquisition from proprietary hardware, thermal printer and label printer integration, networked database synchronization across multiple devices per store, and full graphical user interface (GTK)
- Implemented custom TCP/IP communication protocols enabling real-time data synchronization between distributed embedded devices on local store networks
- Developed low-level Linux system services, hardware drivers, and deployment automation for production embedded environments running on constrained hardware
- Owned full product lifecycle — requirements, prototyping, implementation, testing, and field deployment — maintaining and evolving the platform across multiple hardware revisions
