What I've built, and the teams I've led.

Flayona

Designed and built a Ghana-focused e-commerce and FinTech platform end to end in vanilla PHP and MySQL — Paystack and Mobile Money payments, a Buy-Now-Pay-Later engine with credit scoring, KYC onboarding and four separate role portals.

• Built four distinct authenticated portals — customer, admin/staff, credit officer and distributor — each with its own login, 2FA and password-reset flow.
• Engineered a BNPL engine with credit scoring, digital contracts and a cron job that automatically charges instalments.
• Integrated Paystack (card) and Mobile Money, with signature-verified webhooks reconciling orders.
• Hardened the platform with CSRF protection, TOTP two-factor auth, KYC verification and full audit logging.

Cloud-Based Maintenance Management System

Built OpFix, a cloud-based Maintenance Management System, as my BSc final-year project — a FastAPI + PostgreSQL backend and a React SPA, with role-based access, a multi-stage job workflow and full auditability.

• Modelled a multi-party workflow (store → admin → contractor → engineer → accounts) as an explicit job state machine.
• Enforced role-based access (Admin, Engineer, Client and more) with JWT auth, bcrypt hashing and TOTP 2FA.
• Added audit logging, file attachments, SLA tracking, KPI dashboards and Excel/PDF exports.
• Backed by SQLAlchemy + Alembic migrations, a pytest suite, and deployed on Render with Supabase Postgres.

Julli Jets (Client)

Delivered and maintain a commercial private-charter website (jullijets.co.uk) on WordPress/Elementor, driven by a custom PHP page-generation system I wrote.

• Built a two-layer PHP page builder that programmatically generates Elementor layouts from reusable section helpers.
• Developed mu-plugin shortcodes, a global design system and a charter-request booking flow.
• Collaborated directly with the client and deployed to IONOS hosting via SSH.
