Production software without slow cycles.

I help founders and small teams turn messy product ideas into production-ready software: Go backends, TypeScript and Electron applications, real-time systems, Flutter clients, and web products that look as serious as the product behind them.

01 Approach

The work that wins doesn't look like the work other people ship.

Most engineers ship features. I ship systems. The TagRides backend isn't a Node monolith with a Postgres on the side — it's 9 Go microservices, MQTT over EMQX for real-time location, Kafka for event streaming, Kong as the gateway, PostGIS for routing, Tile38 for geospatial lookups. All of it dockerised, observable, replayable, and built solo.

That kind of depth doesn't come from following tutorials. It comes from owning every layer — auth, routing, payments, push notifications, the matching algorithm, the simulator that lets you test it without 200 drivers on the road. When I tell a client I can ship their MVP in two weeks, what I mean is: I've already built the harder version of their problem. Yours is a remix.

/ Who you're hiring

I'm Oniya. I build the whole thing — so you only have to hire one person.

Most clients reach out thinking they need a team. They need a backend engineer, a mobile dev, a DevOps person, someone for infra, someone for the marketing site. Then they spend two months coordinating four contractors and shipping nothing.

I do all of it. Backend in Go. Desktop and web in TypeScript, Electron, and Next.js. Mobile in Flutter. Infra on Docker + Nginx + Postgres. AI integrations with LiteLLM and Foundry. Brand systems, design tokens, landing pages, contracts. One person, one timeline, one invoice.

That's not because I'm cheaper than a team. It's because shipping fast requires somebody who can hold the entire system in their head at once. That's the part that's actually rare — and that's the part I do.

The pact
  • ↳ A first working version of your product, on a real URL, within 7 days of kick-off.
  • ↳ Daily progress updates. No "I'll have something next week."
  • ↳ A free 20-minute intro call before any commitment. If we're not a fit, we're not a fit.

Hadassah Lifestyle — commerce on web and desktop.

A woman-led lifestyle storefront with a complete identity and owner-friendly operating system.

Translated the client’s interlocking-H reference into a scalable logo family, then carried it across storefront, favicon, social sharing, documents, and a downloadable brand kit. Built catalogue synchronization, validation, WhatsApp-assisted checkout, contact workflows, and production safeguards that deliberately keep online payments disabled until fulfilment and Paystack infrastructure are ready. Added a secure Electron desktop shell in TypeScript with context isolation, sandboxing, restricted navigation, and system-browser handoff for external links.

RelayDesk — local updates, relayed.

One laptop. Every nearby phone. No internet required.

A local-first desktop prototype that turns a laptop into a small private content hub. The operator publishes from one control panel, and anyone on the same Wi-Fi opens a simple address on their phone to see the latest information. Content stays safely on the laptop in SQLite, while WebSockets relay updates to connected phones immediately, even when the wider internet is unavailable.
