Engineering services

We design and build multi-tenant SaaS platforms that can serve multiple clients from a single codebase without data leakage or performance degradation.

This means proper tenant isolation at the database level, role-based access control with fine-grained permissions, and architecture that doesn't require a rewrite when you go from 10 to 10,000 users.

We've shipped multi-tenant platforms across EdTech, church management, school management, and ERP — each handling real user load and live payments.

Before proposing architecture, we read the existing system. Every engagement starts with a technical audit: we map the data model, identify security vulnerabilities, document what works, and flag what doesn't.

We've conducted OWASP Top-10 self-audits, fixed SQL injection and local file inclusion vulnerabilities, externalized hardcoded secrets, added missing database indexes, and replaced predictable PINs — across multiple production platforms.

Architecture isn't just about drawing boxes. It's about understanding the constraints of the system you're building on and making decisions that hold up under real-world load.

We integrate AI into products that need it — not as a demo feature, but as a working component of the system.

This includes multi-provider cascading failover (Claude → Groq → Gemini → OpenAI) so your AI features stay available even when one provider has an outage; AI assistants with tool-use loops and safety gates; AI-powered exam generators backed by Python worker bridges; automated WhatsApp morning briefs and evening digests; and full AI sales-enablement tooling with real-time SSE token streaming.

We've shipped AI integrations into ERP, church management, school management, and standalone sales tools.

Payment integration is not just adding a checkout button. We handle the full payment lifecycle: server-verified webhook processing, idempotent payment records, automated tutor/staff payouts, commission calculations, tax computation verified against local statutory requirements, and Excel export for bank runs.

We've integrated Paystack and Hubtel across multiple production platforms — including a tutoring marketplace with live payments, refunds, and automated payouts to 100+ tutors, and a school management platform with fee tracking and multi-gateway support.

Offline-first matters in emerging markets where connectivity is intermittent. We've built installable PWAs with IndexedDB-backed offline sync that work in the field and reconcile when the connection comes back.

This includes a mobile PWA for site engineers in a construction ERP (attendance, daily records, offline wage calculation), parent and teacher portal PWAs for a school management system, and a church management PWA with offline attendance.

Mobile-first means designed from 360px upwards — not a desktop layout squeezed onto a small screen.

Security is not an add-on. We build with OWASP Top-10 in mind from the start: parameterized queries, secret externalization via environment variables, RBAC at module level, input validation on both client and server, CSRF protection on every form, and rate-limiting on authentication endpoints.

For compliance, we've implemented Ghana Data Protection Act and GDPR-aligned data handling: consent capture, data export, account deletion, and documented remediation of P0/P1 critical findings.

For DevOps: Docker, CI/CD pipelines, AWS and Hetzner deployment, and Sentry-based observability.
