Rock Joystick Technologies — Asaba, Delta State
We build the softwareNigeria runs on.
We build the software Nigeria runs on. One studio. Fintech, sports, logistics, hospitality, education, and events — production-grade SaaS built for how Nigeria actually works.
What We Build
Six kinds of software. One engineering bar.
Every service below is proven by named products in our own portfolio — not a capability we're claiming for the first time on your project.
Product Strategy & Documentation
Every RJT build starts with a full spec suite — scope, data model, and API contract written before a single line of code — so there's no ambiguity between what was asked for and what gets shipped.
Proven by
LedgerNG, Niger Delta Games 2027 Games Management
Full-Stack SaaS Development
Production-grade web, mobile, and desktop applications on one consistent stack — Go on the backend, Next.js and Expo on the frontend — built to run as a real business, not a demo.
Proven by
NairaLedger, EduPrime, LodgePoint
Sports Technology Platforms
Federation-grade systems for registration, competition management, results, and rankings — built for national federations, multi-sport games, and academies alike.
Proven by
National Athletics Federation System, Niger Delta Games 2027 Games Management, Tennis Academy Platform
Fintech & Payments Integration
Paystack-native payment flows, kobo-precise ledgers, and HMAC-verified webhooks — money handling built correctly the first time, because there is no acceptable margin of error on a ledger.
Proven by
TradePoint, LedgerNG, NairaLedger
Offline-First & Field Systems
Software for the field, not just the office — apps that keep working through unreliable connectivity and sync cleanly once signal returns, for riders, farmers, and event staff on the ground.
Proven by
DropGoMart, FarmBridge, EventGate
IoT & Hardware Integration
Software that talks to real hardware — sensor telemetry, store-and-forward buffering for intermittent connections, and dashboards that turn raw device data into decisions.
Proven by
PowerPulse
Portfolio
One studio. An entire ecosystem.
Fifteen products across nine verticals — the breadth and depth of what Rock Joystick Technologies builds, all designed and engineered in-house.
How We Work
A real sequence, not a slogan.
Documentation before code, a consistent production stack, hardening before launch, and support after — the same four steps on every engagement.
- 01
Documentation-first
A full spec suite before any code is written.
Every project starts with a documented scope, data model, and API contract. You review and sign off on exactly what will be built before a developer opens an editor — so there's no drift between what was promised and what ships.
- 02
Build
Production stack, not prototypes.
We build on the Grit Framework: Go, Gin, and GORM on PostgreSQL and Redis for the backend; Next.js for web, Expo for mobile, and Wails for desktop where needed. One consistent, production-grade stack across every product.
- 03
Harden
Security and testing before launch, not after.
Server-side authorization on every request, integer-precision money handling, HMAC-verified webhooks, and test coverage on the paths that matter — payments, data integrity, and access control — before anything reaches a user.
- 04
Ship & Support
Launch, then stay reachable.
Deployment, monitoring, and a direct line back to the team that built it. You own the code and the platform outright, with support and retainer options for what comes after launch.
Engineering Standards
Non-negotiables baked into every product, whether or not you’d think to ask for them.
- Server-side tenant derivation
- Access scope is derived from the authenticated session on the server, never trusted from a client-supplied ID — the class of bug that leaks one customer's data to another.
- Integer-kobo money
- Every monetary value is stored and computed as an integer in kobo. No currency field is ever a floating-point number, anywhere in the stack.
- HMAC-verified webhooks
- Every inbound webhook — Paystack, Termii, or otherwise — is signature-verified before its payload touches application logic.
- Signed asset URLs
- Private files and media are served through short-lived signed URLs, not permanent public links, so access can't outlive its purpose.
- Offline idempotency keys
- Field and offline-first flows write with idempotency keys, so a retried sync after a dropped connection can never double-post a transaction or duplicate a record.
About
Built in Asaba. Built for African markets.
Rock Joystick Technologies is a software studio based in Asaba, Delta State, founded by Duke. We build production-grade platforms for the industries that actually run Nigeria’s economy — fintech, sports, logistics, hospitality, education, agriculture, and events — with the local realities of payments, connectivity, and regulation designed in from day one, not patched on afterward.
We’re a product studio, not a body shop: every engagement follows the same documentation-first, security-hardened process, on the same production stack, whether we’re building a fintech ledger or a national sports federation platform. That consistency is what lets a small studio in Delta State ship at a standard usually reserved for much larger teams.
Our mission is straightforward — build the software African businesses and institutions actually need to run, own, and grow with, without the excuses that usually come with “built for Nigeria.”
FAQ
Questions that come up before the first message.
It depends on scope — a single-platform MVP costs less than a multi-platform product with payments and offline support. Every project starts with a documented scope before we quote a price, so you get a number tied to exactly what's being built, not a guess.
