About denis_dolya

My name is Denis Dolya, and I am an embedded systems engineer from Ukraine with over twenty years of experience. I specialize in the C programming language and low-level algorithm optimization, working extensively with memory-constrained systems, graphics handling, and efficient resource utilization on microcontrollers and multi-core embedded platforms. Throughout my career, I have participated in both industrial and consumer-grade projects, developing practical solutions that balance simplicity, performance, and maintainability.

Currently, I focus on designing new data formats that operate efficiently on constrained devices without relying on external libraries. My goal is to create solutions that are straightforward to implement, minimize memory usage, and remain flexible for different types of graphics. I also dedicate time to studying mathematics and algorithmic optimization, which I consider essential for building robust and reliable systems.

I value clarity, simplicity, and efficiency in both code and system design. I believe that even on limited hardware, code should remain readable, maintainable, and performant. I enjoy sharing knowledge, discussing complex technical problems, and mentoring less experienced engineers to help them avoid common pitfalls that I have encountered over the course of my career.

    Looking at Scar through the eyes of a senior developer the reaction is more curious than dismissive. There is a bit of surprise because in the past system languages were almost alw…

    Restricting PNG to a smaller subset is a reasonable idea, and I did consider it. The challenge is that even a limited PNG still requires handling deflate compression and integrity …
