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.
Build the right thing first
For founders and teams turning rough ideas into usable products.
Let Me Show You What I Can Do
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.
About Me
I'm a Nairobi-based engineer who likes trying different things and doing hard things. My interests range from web development, backend, and full-stack systems to AI automation, running smart contracts, and blockchain development.
It all began as curiosity as an information technology student and grew into building software systems, open-source contributions, AI automation, n8n workflows, AWS cloud tools, and blockchain products. If you want products shipped with Bitcoin, Cardano, Rust, Python, React, Next.js, and AI tools, or you have a product that needs a new feature, reach out. I'm a team player who can help move the work forward and I'm open to learning along the way.
I'm currently learning Mastering the Lightning Network.

How I Help
The stack matters because it reduces delivery risk, not because it fills a badge wall.
Product Interfaces
Clean, fast web apps for dashboards, wallets, marketplaces, and crypto workflows.
Backend Systems
APIs, databases, queues, and service layers that stay reliable under real users.
Delivery & Infrastructure
Practical deployment, observability, and tooling for teams that need to move.
Blockchain & Web3
Wallet flows, smart contracts, signing logic, and on-chain product architecture.
Languages & Systems
Rust, Haskell, and lower-level engineering for performance-sensitive code.
Projects
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.
StackMate
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.
AI agents need to sign blockchain transactions without ever exposing raw private keys.
Open Wallet Standard
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.
Bitcoin Wallet Lab
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 and instantly verify credentials without a centralised authority.
LiteCert — Blockchain Certificate Verification
Certificate verification platform anchored on the Cardano blockchain using Mesh SDK. Institutions issue digital credentials with unique identifiers (e.g. CAR_JOH_01); employers verify instantly via on-chain transaction hash. Privacy-first: certificate data is hashed before blockchain submission.
Build a fully on-chain game for the Dojo Game Night hackathon, accessible via Telegram without crypto knowledge.
Memorabilia
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.
Daily Habit Hub
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.
Computer Vision — Traffic & Attendance
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.
Telegram Bots
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.
Memorabilia
@enter_memorabilia_musem_bot
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.
Capture ideas, links, and notes the moment they hit — recall them later in plain language.
Second Brain
@danmwisecondbrainbot
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.
