Hi, my name is
Kiptoo Dennis.
I build secure on-chain logic.
EVM whisperer. Building gas-smart, trustless systems on-chain that even your grandma could read.
01. About Me
Hello! I'm Kiptoo Dennis, on-chain protocol core engineer based in Nairobi, Kenya. I design MakerDAO-inspired stablecoin engines with simplified governance and fixed parameters.
My commitment to DeFi solidified in 2019 when trying to understanding the 2008 financial crisis. I learned that transparent, auditable smart contracts could avert such systemic failures after realizing that opaque, interconnected banking systems led to the global collapse.
Fast-forward to today, and I've had the privilege of working at a prooveable lottery, automation Agency.
Here are a few technologies I've been working with recently:
- ▹ Solidity
- ▹ Yul
- ▹ Huff
- ▹ Node.js
- ▹ GraphQL
- ▹ Web3.js
02. Where I've Worked
Engineer @ CableGraph
May 2025 - Present
- Comprehensive fuzz testing runs per function to uncover edge cases and validate security invariants under extreme conditions.
- Integration test suite which simulates real-world scenarios including oracle manipulation attacks, flash loan exploits, and multi-user liquidation cascades.
- Daily orchestration of technical roadmaps and design implementation across distributed engineering teams, product design frameworks, and stakeholder alignment protocols.
Developer @ Scout
Jan 2017 - Apr 2018
- Developed and maintained code for in-house and client websites primarily using HTML, CSS, Sass, JavaScript, and React
- Interfaced with clients on a weekly basis, providing technological expertise
03. Featured Projects
DSC Protocol
A simplified MakerDAO-like protocol with no governance fees, wETH/wBTC collateral backing, and algorithmic supply control. Compatible with MetaMask, Ethers.js, Web3.js, and major Ethereum wallets.
- Solidity
- Javascript
- Yul
- Huff
Raffle
The decentralized blockchain lottery (Raffle) is a self-governing probabilistic value redistribution protocol that operates under deterministic execution rules while outsourcing entropy generation to a cryptographically verifiable randomness oracle (Chainlink VRF v2.5).
- Solidity
- Foundry
- Chainlink VRF
- Metamask
EVM-native NFT (Foundry)
EVM-native non-fungible asset system implementing ERC-721 semantics, deterministic minting, invariant-driven testing, gas-optimized execution paths, and formally validated state transitions using Foundry.
- Solidity
- Foundry
- IPFS
- Javascript
