— MARKETPLACE
Nigeria's skilled-workers marketplace. Built from scratch.
The problem was trust. Homeowners in Nigeria couldn't find reliable skilled workers — and skilled workers couldn't find consistent work. Craigslist-style listings had no accountability, no payment protection, and no way to verify anyone on either side.
RentLoud solved this by combining identity verification, real-money escrow via Flutterwave, OTP job confirmation, and WhatsApp-based automation into one platform. Workers get verified, homeowners pay into escrow, and funds only release when the job is marked complete by both parties.
Building a two-sided marketplace isn't one problem — it's twelve. Onboarding for two different user types. Dispute resolution. Split disbursements. Queue-backed notifications across email, SMS, and WhatsApp. We shipped every one of them in production, not a prototype.
What was built
- Two-sided onboarding with identity & skill verification
- Flutterwave escrow with split disbursement & fee logic
- OTP job-completion confirmation & dispute resolution
- WhatsApp & email automation via queued workers

— SAAS PLATFORM
$17K MRR in 8 months. From zero.
Email copywriting was broken for online business owners. Hiring a copywriter was expensive and slow. Generic AI tools produced bland, template-sounding emails that didn't convert. EmailWritr was built to solve the gap in the middle — a SaaS tool trained on 120+ proven email frameworks for affiliates, course creators, and digital product sellers.
The platform needed to feel premium, convert well, and scale without breaking. We built multi-tenant authentication, subscription billing with Stripe webhooks, a structured campaign builder with 120+ campaign types, and a dashboard that let users generate complete email sequences in minutes — not hours.
Within 8 months of launch, EmailWritr was generating $17,000 MRR with 140+ paying customers and 99.98% uptime. Every architecture decision — from how campaigns are stored to how billing webhooks are retried — was made with that trajectory in mind from day one.
What was built
- Multi-tenant SaaS with role-based access control
- Stripe subscription billing with webhook retry logic
- 120+ email campaign frameworks & sequence builder
- Customer dashboard, admin analytics & usage tracking

— DOCUMENT MARKETPLACE
HSE compliance, professionally delivered online.
Health, Safety & Environment professionals across Nigeria and beyond were stuck sourcing compliance documents through informal channels — WhatsApp groups, USB drives, unreliable PDF links. The work was expert-level; the distribution was amateur.
RinathhseHub became the dedicated platform for HSE documents, training materials, and consultancy services. A structured document marketplace where buyers can browse, preview, purchase, and download certified HSE resources — risk assessments, method statements, safety plans, audit templates — without leaving the platform.
The platform handles both digital product delivery and service bookings. Cart management, secure checkout, instant download fulfillment for digital documents, and a service request system for project HSE management and manpower supply engagements.
What was built
- Digital document marketplace with instant download delivery
- Service booking system for HSE consultancy & training
- Category browsing: risk, training, inspections, manpower
- Admin content management & order fulfillment dashboard

— AI SALES TOOL
Your sales team, running while you sleep.
Most small business owners lose leads in the gap between contact and follow-up. A prospect fills in a form at 11pm. No one responds until Monday. The deal is already dead. SilentSales was built to close that gap with AI-powered, event-triggered sales sequences that run without a human in the loop.
The system connects to your CRM, listens for lead events, and fires personalized follow-up sequences generated by GPT-4o — adapting tone, messaging, and timing based on the lead source, the service enquired about, and how the prospect has engaged so far. Each message sounds written, not templated.
Sales teams using SilentSales report an average 3.2× increase in first-response rate and meaningful reduction in leads that go cold before a human gets to them. Cost monitoring, output validation, and fallback routing are built in from day one — so you know what it's doing and what it's spending.
What was built
- Lead event listener with CRM & form webhook integration
- GPT-4o sequence generation with prompt guardrails
- Adaptive follow-up timing based on engagement signals
- Cost monitoring, output validation & fallback routing

How Dkingstech works
Six steps, no theatre, no surprise invoices.
Every engagement runs the same way. You see the staging URL, ship to it every Friday, and walk away owning the keys. Here is what each step actually looks like.
Planning
Scope, timeline, and success metrics agreed in writing before a single line of code is touched.
Analysis
Your business logic, existing systems, and user flows mapped before any architecture decisions are made.
Design
Data models, API contracts, and system architecture documented. You see exactly what's being built — before building starts.
Implementation
Code ships to a live staging URL from day one. Progress is visible every Friday — no black-box builds, no "trust me" updates.
Testing
Every critical path tested against real data before go-live. Edge cases documented, bugs fixed — not handed off as "known issues."
Maintenance
You own the codebase, the server, and the credentials. Updates happen fast — not on a slow ticket queue.
