What I can build for you

I work remotely with businesses across Nigeria and internationally, building business websites and custom software around the way they work.

Business websites

Responsive websites that showcase your business, explain your services, and make it easy for customers to get in touch.

Custom business software

Purpose-built tools for the way your business works: CRM systems, database-backed applications, internal tools, workflow dashboards, and integrations that bring your operations together.

01Dashboard overview

A VS Code extension for dev time intelligence — automatic coding-time tracking, per-project streaks, and a full in-editor analytics dashboard. Everything runs locally: no account, no backend, no telemetry. Headed for the VS Code Marketplace.

  • Measures active time, not elapsed: idle gaps pause the clock and resume the same session
  • Counts edits made by AI agents and CLI tools, via a multiset diff over per-line hashes
  • Terminal-style dashboard and Activity Bar sidebar: year heatmap, language split, per-project targets
  • Exports a shareable day card, a two-page PDF report, and the raw data as CSV or JSON
Built with
TypeScript, VS Code API, Canvas, jsPDF, esbuild

01rabbithole today

Terminal companion for Rabbit Hole — reads the extension's local activity data and prints coding stats without leaving the shell. Written in Go with a from-scratch flag parser instead of a framework, and a pure-Go SQLite reader so it needs no C toolchain anywhere in the build.

  • Seven subcommands on a hand-rolled parser that accepts flags in any position
  • Cross-compiles all 6 platform targets from one Linux runner — no cgo, no matrix build
  • CI-gated releases: the tag must match the version constant or the build fails
  • Installable via Homebrew, Scoop, a checksum-verifying install script, or direct download
Built with
Go, SQLite, GitHub Actions, Homebrew, Scoop

01Landing page

A survey platform for building questionnaires, sharing them with one link, and watching answers arrive the moment they are submitted. Four question types with image support, private drafts until publish, and per-question results with a participant view.

  • Responses stream into the results dashboard in real time: no refresh, no export step
  • Dynamic question types rendered from a shared schema, validated with zod
  • Row-level security on every table, with bot protection on public submissions
  • Media-rich questions: image attachments, picture-choice options and respondent uploads

About

Full-stack developer based in Kaduna, Nigeria and Istanbul, Türkiye. I build business websites and custom software, from CRM systems to database-backed tools that support day-to-day operations.

I build and operate full-stack products end-to-end — most recently a production aviation platform handling real payments, webhooks, and transactional email. I write tested TypeScript, ship through CI/CD, and use agentic dev tools daily to move faster without cutting corners.
