Services
I'm an independent software engineer that offers consultations related to software development and optimizations, writing new code, and updating an existing code to be faster. In addition, I can be hired to be part of a larger development team when it comes to developing either new or existing project (long-term). I also offer commercial support for AsmJit and Blend2D libraries and consultations in this area.
I prefer to work on projects where performance matters and where C++ language is used for its efficiency and not for legacy reasons. I can use other programming languages too, like Python, JS/Node.js, and Golang, but I'm not actively looking for opportunities that would involve writing code in these languages without focus on high-performance.
Contracted Work
I'm offering a contracted work in the area of software development, architecture design, and consulting. I'm expert in the following areas:
Cross-Platform C++
- Knowledge of the C++ language up to C++23 and a daily user of C++20
- Knowledge of operating system APIs including Windows, Linux, BSD variants, and Apple platforms.
- Build systems and package managers including cmake, conan, and vcpkg
- Writing a production-grade code in C & C++ that is robust and properly handles corner cases and error conditions
- Experienced and a daily user of tools like ASAN, UBSAN, MSAN, TSAN, perf, and valgrind
High-Performance C++
- CPU specific optimizations targeting AVX2, AVX-512 (all possible variations), and AArch64/NEON CPU extensions
- JIT compilation targeting X86, X86_64, and AArch64 CPU architectures using AsmJit or other tools
- Using multi-threading and atomic operations to implement lock-free solutions in multi-threaded data processing pipelines
Other C++ Skills
- Designing easy to use and clean interfaces (APIs) of libraries so the API can be easily consumed by users
- Supporting everything I write with tests and benchmarks so the safety and performance of the code is validated
2D Rendering
- Design of 2D rendering engines, mostly CPU renderers that use SIMD instructions and multi-threading
- Experience with 2D rasterization and composition pipelines (advanced implementation in Blend2D)
- Pixel effects (adjustments, color matrix, ...) and convolutions such as blur, erosion, dilation, ...
- Text processing and rendering including advanced use of OpenType technology
- Decoding and encoding raster and vector image formats (PNG, SVG, ...)
Data-Processing Pipelines
- Implementing SQL or custom query engines for processing big data, possibly unstructured
- Acceleration of binary format decoding & encoding by using SIMD instructions
- Acceleration of date-time processing, geo-hashing, vector operations, and other common functions used in query engines
General Skills
- Experienced with common software development methodologies so I can work reliably with others
- Flexibility - A passion for exploring areas I haven't worked on in the past
