LANREAKINTAYO
I design and build resilient backend systems and EVM smart contracts that teams ship with confidence.
About Me
Curiosity and discipline are my compass.
I wrote my first “Hello World” in 2019 and started shipping Android apps by 2021. One of them, Freshers' Guide, solved a problem I faced as a new student and ended up being downloaded by hundreds across the faculty. That gave me an early masterclass in shipping software people rely on.
In 2022, I pivoted to writing smart contracts. Since then, I've built several DeFi protocols, earned paid findings in CodeHawks audits, and recently placed 2nd globally at the Initia Hackathon with Flowroll.
Currently, I build backend and smart contract systems on EVM chains, with the versatility to craft beautiful frontend interfaces when a product calls for it.
Where I've Built
Revotek Global
Software Engineer (Blockchain)
nowArchitected a suite of production-grade smart contracts including Staking, Swaps, On-chain Referral Systems, and IDOs with automated vesting logic. Built the complete full-stack integration using Wagmi/Viem for real-time state synchronization and reduced gas costs by 20% through audit-driven optimizations.
Practicode Academy
Security Researcher
InternshipPerformed invariant fuzzing with Echidna and wrote executable PoC exploits in Foundry. Utilized raw EVM assembly (Huff/Yul) for extreme gas optimization and low-level stack manipulation.
The SkillsForge
Software Engineer
InternshipUncovered 2 valid vulnerabilities in the TempleGold protocol audit on CodeHawks. Built a lending/borrowing platform and a modular DAO voting system from scratch without third-party integration.
GRIT Lab Africa
Software Engineer
FellowshipSelected as top 1% talent across Africa for an intensive engineering fellowship, graduating with Distinction. Collaborated with team to devise a winning solution for the South African DSI & SACNASP during the JBS Innovation Lab hackathon.
Pyvot360
Mobile Application Developer
Full-timeDeveloped core APIs to support mobile functionalities. Suggested and implemented new mobile products while collaborating closely with colleagues to improve app experience.
What I Built
Flowroll is an omnichain, yield-bearing payroll protocol built natively on Initia.
What's New?
Thoughts and write-ups on things I learnt and built along the way
Understanding and Resolving RPC Issues in Blockchain
Understanding ERC-4626: The Tokenized Vault Standard
Understanding Sandwich Attacks in DeFi
Smart Contract Development Frameworks: Foundry vs Hardhat
What I Build With
Where I Stood Out
This is where I stress-test my skills to tackle complex, real-world challenges under tight deadlines, showing my technical agility and problem-solving speed.
2nd Place Winner, INITIATE Hackathon Season 1
Built Flowroll as a solo developer on Initia appchains, placing 2nd overall among 572 global participants across 94 eligible projects.
$ codehawks audit --scope=temple-gold
> Target: EVM Staking & Reward Contracts
> Findings: 2 Valid Severities Identified
> Status: Bounty Rewarded & Verified
Temple Gold Audit (Competitive)
Collaborated in a 3-person security team competing against 80 researchers, successfully identifying 2 valid vulnerabilities and earning a bounty reward.
Top 10 Finalist, Innotech Hackathon
Our team's project, MedixSync, was selected as a top 10 finalist, standing out in a highly competitive field of over 60 engineering teams.
Top African Gritters Recognition
Part of the specialized development team delivering technological solutions for the South African Council for Natural Scientific Profession (SACNASP).
