My contribution to open-source

Software Architect and Compiler Optimization Engineer​

I writing secure, highly optimized code and building robust, scalable architectures. My journey began with programming microcontrollers like 8051, PIC, AVR, and 8086, where I developed my first RTOS and worked on hardware projects in a garage with a college friend. My foundational expertise lies in low-level programming with Assembler, C, and Verilog. In the pre-GPU era I developed numerous highly optimized firmware solutions for devices such as a Multifunctional Caller-ID with Voice using 64k ROM assembler code, 4-voice polyphony on an 8052 running at 20MHz, a billiard timer with a remote control featuring encryption and an RG LED screen with a 16x8 register block.

Programming Languages & Compilers​

• Researched compilers since 2012 driving the development a high-performance programming language ACPUL.
• Fixed Valgrind for 64-bit MacOS.
• Optimized Python’s GIL to support 30,000 threads without locks in 2008.
• Designed a real-time reverse debugger and VM architecture focused on peak performance without JIT with a math exprtk based VM.
• Improved DCC decompiler outputs for better C translation.
• Developed a high-performance database cache and SQL PL for it.

Apple​

• iOS hacker since 2008. I stared from my iPhone 2G Q3 2007

Cryptography & Blockchain​

• Optimized ZCash Equihash CUDA miner for performance gains.
• Contributed to Komodo's Ledger Nano firmware and adding x86 support for debugging cryptographic protocols and algorithms.
• I worked on zk-SNARKs to integrate libzk into Ethereum
• Adding ZK ot EVM libsnarks and Solidity implementation of zk-SNARKS.
• Zero Knowledge smart contracts for Partisia
• EVM assembly gas optimization for Oracles and my SSTORE packing algo

Artificial Intelligence & GPUs​

• Developed GPU kernels and assemblers for benchmarking hardware configurations (RTX 4090, A100, H100).
• Created KudoMine, the world’s first visual mining algorithm for AI benchmarking.
• Extensive experience with TensorFlow and TinyNN optimization. Operating Systems & Embedded Development
• Created RTOS, OS, and virtual machines tailored for high-performance applications.
• Developed embedded Linux hardware drivers, both with and without MMU.
• Optimized cryptographic algorithms like 3DES for secure gaming VMs on AVR and mobile wallets.
• Worked on the RSA Challenge and designed the core of a network security scanner.

Media & Streaming​

• Optimized streaming of 16-channel spatial audio to multiple web browsers.
• Enhanced performance of Erlyvideo (Erlang video streaming server) with RTSP. Built a custom VNC solution to control Mac from iOS using FFMPEG and RTP with low latency.
• Optimized H.263 hardware decoding on Au1200 CPUs.
• Developed FFLAN, a video search tool based on frame analysis.

Achievements​

• Designed high-performance architectures for complex systems.
• Pioneered advancements in compilers, real-time systems, and AI-driven GPU benchmarking.
• Contributed to cryptographic and media technology innovations.
