Full-stack & systems engineer. I build and ship across the TypeScript ecosystem, cloud infrastructure, and web3 — from startup MVPs to production distributed systems.
I care about clean, maintainable code, security by default, and software that holds up under real load.
- 🔭 Building distributed systems in Go and Rust, and going deeper on web3 (Rust smart contracts, ZK proofs)

Sluice — Distributed job scheduler
Go · PostgreSQL · Redis · etcd
Horizontally scalable, durable scheduler with at-least-once delivery and idempotency keys. PostgreSQL as the durable source of truth with a Redis hot path; leader election via etcd for high availability. Instrumented with Prometheus metrics and OpenTelemetry traces. Designed for 10k+ jobs/sec on commodity hardware.
Cloud Shield — Serverless cloud-security posture manager (CSPM)
Python · AWS SAM · Lambda · DynamoDB
Continuously audits AWS accounts against security policies on an hourly schedule. Assumes read-only roles into member accounts via STS for multi-account coverage; tracks every finding through a full lifecycle (acknowledge / snooze / exempt / resolve) with an append-only audit trail. Run-over-run diffing distinguishes new, regressed, and exempted findings. 104 passing tests.
Velora — Kanban board app
Next.js · Prisma · NextAuth · PostgreSQL
Drag-and-drop board with label and priority management, plus full credential auth including email verification and password-reset flows.
Best Secondary — Educational platform
Next.js · TypeScript · Tailwind CSS
Educational web platform for secondary-school students — designed, built, and deployed to production.
Currently a B.Tech Software Engineering student at FUTA (Federal University of Technology, Akure), shipping production work alongside my degree.
