• LLM DSPy optimization pipeline — built a few-shot optimization pipeline for Nustom (YC, AI code-gen for whole SaaS apps) to improve algorithm performance.
• GitHub scraper — built large-scale crawler for Magic.dev (frontier AI code-gen), boosting data collection + analysis throughput.
• Customer identity scanners — robust DB scanners that verify customer identities at scale, improving security + data integrity.
• Novel key-derivation scheme for EK-CDSA — invented and authored research paper.
• Hardware wallet apps — Layer-1 blockchain ledger apps in C on microcontrollers with 4KB RAM.
• Full-stack for a YC company — FastAPI backend + React frontend + LLM features.
• Stripe integrations for an AI self-serve product.
• AI voice agent POC for an enterprise customer-service company.

• In-depth research on zero-knowledge proofs for WebAssembly (WASM), advancing privacy-preserving cryptographic primitives for the wallet stack.

• Designed and shipped a high-speed algorithmic trading system that hit #1 global speed for its specific strategy.
• Distributed architecture across multiple servers — scalable, reliable, real-time.
• End-to-end ownership: strategy research, capital raise, deployment to live production.

• Built real-time RF receiver controllers in C++ for military-grade communication systems, improving reliability and throughput.

• Owned the algorithms tracking half the world's buses in real time, refreshing every minute.
• Built predictive models + schedule-optimization tools that materially improved transit reliability.
• Led the algorithm team — set technical direction, deployed scalable backend, mentored engineers.

• Spearheaded three advanced C++/WinAPI security applications that materially expanded unit capability.
• Implemented no-fault, high-tolerance development practices for software running under hard constraints.
• Designed a comprehensive data-parsing system in C# that optimized core data workflows.
• Original Win32 API research — pioneered component-integration methodologies for security tooling.
• Led the C programming curriculum for new recruits; trained and mentored the next intake.

• Engineered airborne imaging systems in C++ — performance + capability improvements to the platform.
• Killed thousands of compiler/linker warnings across a multi-million-line C++ codebase, achieving a clean stable build.
• Refactored extensive code libraries — reduced technical debt, improved maintainability.

Created a new investment asset class: a system that mints entire Ethereum proof-of-work blocks as unique digital assets, with each transaction fully utilizing a single block.

• Solved complex challenges in Ethereum's PoW mechanism to optimize transaction execution.
• End-to-end: conceived the idea, collaborated with a world-class artist, drove marketing, raised funding, and shipped the technical solution.
