Building blockchain and AI products that don't just work. They move forward.
I help businesses, institutions, and startups turn product ideas into shipped applications using web, cloud, AI automation, crypto, and full-stack engineering.
No obligation, just a 15-minute call to map the next practical move.
For founders and teams turning rough ideas into usable products.
A quick video introduction to my work and approach to development.
Watch this introduction to learn about my background, skills, and what makes me excited about building amazing products.
I'm a Nairobi-based engineer who likes doing hard things — from full-stack web systems to AI automation, smart contracts, and blockchain products. What began as curiosity as an IT student grew into shipped software, open-source contributions, and products built with Bitcoin, Cardano, Rust, Python, React, Next.js, and AI tools. If you have a product to ship or a feature to move forward, reach out.
I'm currently learning Mastering the Lightning Network.

Whether you need payments, AI, blockchain, smart contracts, automation, or an open-source collaborator — I'll ship it.
Stripe, M-Pesa, PayPal, and on-chain payments — wired into your site or product, end to end.
LLM-powered features, chatbots, semantic search, and RAG pipelines using OpenAI, Groq, Gemini, or LLaMA.
Bitcoin, Cardano, EVM, Solana, Starknet — wallets, signing, transactions, and ecosystem tooling.
Solidity, Plutus, Cairo — written, tested, audited, and deployed to mainnet with confidence.
AI agents, workflow automation, scheduled jobs, and bot infrastructure that actually ships.
Active contributor to IntersectMBO, Bitcoin, and Cardano. I can ship inside your repo, not just around it.
The stack matters because it reduces delivery risk, not because it fills a badge wall.
Clean, fast web apps for dashboards, wallets, marketplaces, and crypto workflows.
APIs, databases, queues, and service layers that stay reliable under real users.
Practical deployment, observability, and tooling for teams that need to move.
Wallet flows, smart contracts, signing logic, and on-chain product architecture.
Rust, Haskell, and lower-level engineering for performance-sensitive code.
Selected work in Bitcoin, Cardano, Starknet, AI, and full-stack.

Stacks builders and founders need a trusted way to find co-builders, with partnerships verifiable on-chain rather than just word-of-mouth.
Builder-partner marketplace on Bitcoin L2 (Stacks). Project owners post partner requests; builders browse, apply with a pitch, and get accepted — every key action (registration, application, acceptance, mutual endorsement) is anchored on-chain via four Clarity smart contracts on Stacks mainnet (Nakamoto epoch 3.4). Off-chain Postgres handles search and metadata; on-chain principals form the verifiable reputation trail.

Most captioning systems only transcribe speech — accessibility and content teams need to know what actually happened in a video.
Multi-agent video intelligence system built for the AMD Developer Hackathon ACT II. 13 specialised AI agents (scene detection, Whisper ASR, VLM vision understanding, emotion analysis, self-verification) collaborate to turn one video into captions in 4 styles, rich accessibility descriptions for blind users, an emotion timeline, highlights, memes, and platform-ready social posts.

AI agents need to sign blockchain transactions without ever exposing raw private keys.
Multi-chain AI agent wallet supporting 9 chains (EVM, Solana, Bitcoin, Cosmos, XRPL+). Policy-gated signing tokens — AI agents never hold raw keys. Includes Solana + EVM signature verification and live testnet transactions.

Show exactly how Bitcoin works at every layer — from key generation to signed, broadcast transactions on testnet.
Educational Bitcoin wallet on testnet4 built on what I learned from Bitcoin Dojo. Generate all three address types (P2PKH, Nested SegWit, Native SegWit) from a single key, receive testnet coins, build and sign a real transaction, then broadcast and watch it confirm on-chain. secp256k1 + ECDSA + RFC 6979 implemented from scratch in a vendored bitcoin_dojo crate. Includes signature malleability demo.

Give institutions a tamper-proof way to issue, verify, and revoke credentials without a centralised authority.
Blockchain credential-issuance platform on Cardano: certificate NFTs minted via Mesh SDK and Blockfrost, an Aiken on-chain revocation contract, and a zero-knowledge privacy layer (Midnight Network) so only hashes touch the chain. Certificate metadata is pinned to IPFS via Pinata; employers verify instantly via on-chain transaction hash.

New contributors face unfamiliar repos with no map — which files matter, what could break, where to start.
AI developer tool that analyzes a GitHub repo and issue, maps dependencies, and generates an implementation roadmap with code guidance and risk notes — plus an interactive "Ask Bob" Q&A over the analysis.

Build a fully on-chain game for the Dojo Game Night hackathon, accessible via Telegram without crypto knowledge.
Fully on-chain memory card matching game on Starknet, built for the Dojo Game Night hackathon. Playable as a Telegram Mini App (@enter_memorabilia_musem_bot) — no wallet or gas fees to start. Features Account Abstraction, gasless transactions, 3 eras, 15 levels, daily challenges, and NFT minting via Cartridge.

Build exercise habits through daily accountability, community support, and on-chain proof of progress on Avalanche.
Modern fitness tracking app combining social accountability with Web3 rewards. Daily check-ins across gym, running, cycling, yoga and more. Visual streak tracking, community feed, professional coaching connections, and $HABIT token rewards + "Proof of Progress" NFT minting on the Avalanche network.

Real-time vehicle speed, traffic jam detection, and person tracking at the edge with zero cloud latency.
Edge-native CV system for real-time traffic sensing and multi-class object counting. Dual-stack architecture: Python (Ultralytics + DeepFace for gender analysis) for prototyping, and Rust (ort/ONNX Runtime + OpenCV) for high-performance edge inference. Homography-based pixel-to-meter calibration for science-grade speed data. Designed to run on NVIDIA Jetson.
Bots and Mini Apps shipped on Telegram. Tap any to chat — they're all live.

Make a fully on-chain Starknet game playable by anyone, without a wallet or gas.
Telegram Mini App entry point for the Memorabilia memory-card game on Starknet. Account Abstraction handles wallet creation behind the scenes; players match cards across 3 eras and 15 levels with gasless transactions and NFT minting via Cartridge.
@btc_opensource_projects_bot
Finding high-signal open-source contribution opportunities means trawling issue trackers by hand every day.
Autonomous agent that scans GitHub repositories daily for good-first-issue, help-wanted, and bug labels, analyzes each with an LLM, and delivers a prioritized digest via Telegram. Built with Node.js, Gemini/Groq/Ollama, Airtable, and cron scheduling.
@danmwisecondbrainbot
Capture ideas, links, and notes the moment they hit — recall them later in plain language.
Personal AI second-brain on Telegram. Forward links, drop voice notes, jot ideas; ask questions in natural language and the bot retrieves with context. Built around an LLM + vector store so semantic search beats keyword grep.
Questions, architecture reviews, wallet ideas, smart contract builds, or AI agent automation: send the signal and I'll help you find the next step.
