I build custom ERP, CRM & inventory systems

Built and evolved two major business systems:

• SupreTek Suite — A modular CRM and operations platform covering products, orders, storefront administration, session authentication, role-based access and executive dashboards. Owned work across Next.js, NestJS, Prisma, PostgreSQL, UX, APIs and release validation, reaching 89/89 runtime checks across 17 verified data models.

• DERA Autos — A secure cloud inventory and operations system for USA-to-Nigeria vehicle businesses. Built workflows for VIN and vehicle records, shipments, warehouse and yard tracking, documents, reservations, customers, sales, finance, approvals, delivery and audit trails. Implemented server-enforced Request → Approval → Mutation security and role-based permissions, with 250/250 vehicle authorization checks and 369/369 platform-protection checks passing.

I build complete business software from requirements and interface design through APIs, database architecture, testing and deployment.
