Selected work
A selection of engagements where Calstins delivered the full lifecycle, from the first strategic question to the live product.
E-Commerce & Digital Growth
Full lifecycle engagement — business model review, digital strategy, product delivery, and ongoing growth management. The client requested a retainer post-launch.
Full PM + full-stack development role. Implemented SEO architecture, rebuilt checkout, integrated Paystack with Stripe fallback, and category-based delivery logic.
Logistics Platform
Architecture design, vendor selection, and full production delivery for a Nigerian logistics platform with zone-based pricing and multi-party payment infrastructure.
Community & Mobile Platform
Product scoping and end-to-end delivery of a faith-based community platform — mobile application and web dashboard with Paystack-integrated commerce.
Event & Ticketing Infrastructure
Platform architecture and full delivery for one of Nigeria's largest digital event ticketing systems, handling peak event loads with Paystack payment infrastructure.
SaaS Product
A peer-to-peer currency exchange platform with real-time order matching, escrow management, and a multi-platform presence across web and mobile.
Web Platform
Nigerian real estate platform — ROI calculator, investment pools, VR tours, admin.
Commerce Platform
E-commerce platform delivery for a Nigerian grocery brand — including WhatsApp-integrated order automation and zone-based delivery infrastructure.
Hospitality SaaS
A multi-tenant platform that lets hotels run bookings, rooms, staff and their own website from one place.
Calstins identified a gap between what independent hotels need and what they can afford to run, then planned and built Ayohotel as a product: tenant and subscription plans, a content system for each hotel's public site, role-based staff access and platform administration. Notification credentials are managed centrally by the platform team, while each hotel owner configures only their own payment gateways, so the platform never holds a tenant's money.
Outcome. Delivered end to end by Calstins, from product definition to a running multi-tenant platform with plans, tenants and a CMS.
Retail SaaS
A point-of-sale platform for grocery stores, supermarkets, pharmacies and electronics shops, covering inventory, accounting, HR and procurement.
AYOPOS applies the same product thinking as Ayohotel to retail: one platform for sales, stock, purchasing, accounts and staff, with roles such as storekeeper and cashier, subscription plans chosen at signup, and a website-sync feature that links a client's online store to their stock. It was planned and built in phases by Calstins.
Outcome. Built in phases by Calstins as a multi-tenant product, with plan-based features and a website and store sync for connected clients.
