Trading platform on Solana

0DTE

Options trading on Solana, for contracts with zero days to expiry

Same-day options only work if prices and positions reach traders the moment they change. The platform pairs on-chain programs with a streaming data pipeline from the chain to the browser, plus a short path for new users to fund a wallet and start trading.

What I built

  • On-chain programs in Anchor
  • Geyser and Yellowstone listeners streaming chain updates
  • Indexers in Rust and TypeScript
  • Real-time delivery to the browser over WebSockets, backed by Redis
  • Coinbase Onramp for card funding and Dynamic for wallet sign-in

Infrastructure · 2026

SkilledCrow infrastructure

One server sized to host 10+ products for about $150 a month

A small studio can't pay for a managed database per product. I moved SkilledCrow off DigitalOcean, ran a split app and database setup on Hetzner, then consolidated everything onto one Netcup root server. Each product keeps its own Postgres cluster, so a restart or a runaway query in one product no longer takes the others down with it.

What I built

  • A separate Postgres 17 cluster for each product, each with its own cgroup limits
  • PgBouncer as the single private entry point for every app
  • Coolify for app deploys and systemd for long-running services and timers
  • pgBackRest backups shipped off-site to Cloudflare R2

Multi-tenant SaaS · 2026

MatchdayHub

Branded websites and matchday tools for football clubs

Every club gets its own branded website and a simple admin dashboard, all served from one shared platform. The main workflow is posting a result. The site updates, and the platform renders branded share graphics ready for WhatsApp and social media. Sponsors appear on those graphics, which is how clubs pay for it.

What I built

  • A multi-tenant Go and Gin API serving every club from one deployment
  • A background worker that renders the branded share graphics
  • Custom domains for each club
  • The design system and full screen set for the admin, public site and graphic templates

DNS and domains · 2026

itoka.ng ↗

Itoka

DNS hosting for .ng domains, on the way to becoming a registrar

Getting DNS working on a .ng domain once took me more than two days. Itoka fixes that from the bottom up. It starts as DNS hosting on its own nameserver, used first for SkilledCrow's own domains, and grows into a full .ng and .com.ng registrar once NiRA accreditation is complete.

What I built

  • The web app and landing page, served from itoka.ng
  • The backend for managing DNS zones and records
  • A dedicated nameserver on its own VPS
  • The groundwork for NiRA registrar accreditation

  • Nameservers

Client platform · 2026

Voguish Kitchen

Online ordering, payments and delivery tracking for a restaurant

A standalone platform built for one restaurant. Customers order and pay online, the kitchen runs everything from a seller dashboard, and each order can be tracked end to end until it's delivered. SkilledCrow earns a ₦100 platform fee on every order, so the platform pays for itself as orders grow.

What I'm building

  • Customer ordering with online payment
  • End-to-end tracking from order to delivery
  • A seller dashboard for managing orders
  • A fully responsive layout designed for every screen size

About

Engineer, founder, still learning

I've been building for the web for about five years, and moved into Web3 along the way. In November 2025 I incorporated SkilledCrow Technologies Limited, a product studio in Ekiti. I hired and led a small team, built products for clients and for ourselves, and now run the studio on my own.

I'm also the technical co-founder at Pregame, a US-based crypto company.

I like owning the whole path, from the data model and the API to the interface, the server and the backups. Right now I'm going deeper on distributed systems by building dkv, and studying networking and security on the side.
