Building full-stack products with AI for the next billion users

I'm a full-stack developer who specializes in integrating AI into real products. With 5+ years of experience, I've shipped platforms used across fintech, insurtech, and agri-commerce, from frontend UX to backend APIs and production infrastructure.

My sweet spot is the intersection of robust product engineering and practical AI. I pair OpenAI, LangChain, and vector databases with React, Next.js, Node.js, TypeScript, and Python to ship reliable, measurable features into production.

I'm on a mission to build African tech products that are globally competitive, powered by strong full-stack foundations and thoughtful AI adoption.

Things I've shipped

Full-stack and AI-enabled projects with real users, real impact, and measurable outcomes.

🧾

ZamERP — Mini ERP for Zambian SMEs

✦ Newest
Personal Project · Next.js + NestJS

A production-ready, ZRA-compliant ERP platform built for small and medium businesses in Zambia. It combines invoicing, inventory, accounting, customer management, audit logs, and KPI reporting in a multi-tenant architecture with role-based access.

Problem

Zambian SMEs struggle with disconnected invoicing, inventory, and accounting workflows while still needing ZRA-compliant operations.

Design decisions

Built a multi-tenant architecture with role-based access, transaction-safe invoice and inventory flows, and API-first modules documented with Swagger.

Trade-offs

Prioritized data integrity and compliance over rapid schema changes, which increases migration discipline and initial implementation complexity.

Scaling approach

Scale by tenant isolation, index-heavy Postgres queries, cached KPI reads, and background workers for heavy reporting and reconciliation tasks.

◆ZRA-ready invoice workflow
◆Multi-tenant data isolation
◆Swagger API documentation
◆Inventory auto-deduction on invoice payment

Payment Engine — Payment & Billing API

Personal Project
Personal Project · NestJS + PostgreSQL + Redis

A backend payment orchestration engine for Lenco and Stripe integrations, with subscription billing, idempotent payment processing, refund flows, HMAC-signed webhooks, and full transaction audit logs.

Problem

Payment retries, provider differences, and subscription billing can create duplicate charges and weak transaction traceability.

Design decisions

Used idempotency keys, a provider adapter layer for Lenco and Stripe, HMAC-signed webhooks, and full payment audit logging.

Trade-offs

Strong auditability and idempotency introduce additional storage, queueing, and operational complexity compared to a simpler payment flow.

Scaling approach

Run stateless API instances horizontally, process webhook and sync work in queues, and partition payment logs by tenant and time.

◆Idempotent payment initiation to prevent duplicate charges
◆Subscription plan and lifecycle management
◆Refund and payment status sync workflows
◆Webhook delivery tracking with audit logs

Agronova Fleet — Fleet Management System

Personal Project · Next.js + FastAPI

A full-stack fleet management platform built with a Next.js dashboard and a FastAPI backend, containerised with Docker and deployed on Vercel and Railway respectively. Manages vehicles, drivers, routes, and operations in real time — demonstrating production-grade full-stack architecture beyond the JavaScript ecosystem.

Problem

Fleet operations data is often spread across teams, making real-time vehicle, driver, and route visibility difficult.

Design decisions

Separated a Next.js operations dashboard from a FastAPI service layer, with Dockerized deployments and Alembic-managed schema changes.

Trade-offs

A polyglot stack improves flexibility but increases team context switching, tooling complexity, and debugging overhead.

Scaling approach

Scale API and workers independently, optimize route and status queries with targeted indexing, and cache high-frequency dashboard reads.

Agronova Farms

Personal Project · Next.js + Supabase

A full-stack agri-ecommerce platform built to help small-scale farms earn more and cut post-harvest losses by connecting them directly to buyers. Features 420+ live products, real-time order tracking from checkout to delivery, and a mobile app currently in review on the Play Store.

Problem

Small-scale farms lose margin and produce due to weak market access and delayed, manual order coordination.

Design decisions

Built a real-time marketplace with Supabase-backed auth/data flows, payment integration, and a shared backend model for web and mobile.

Trade-offs

Real-time updates improve user trust but increase infra cost, and synchronizing product/order logic across clients adds complexity.

Scaling approach

Use catalog pagination, aggressive indexing for search and orders, async notifications, and staged archival for historical transaction data.

◆30%+ income boost for small-scale farms
◆420+ products live
◆< 2 min order confirmation
◆Mobile app on Play Store (in review)
