I am a full-stack engineer based in Tanzania, building production systems for universities, government agencies, cooperatives and health research projects.
Most of my work lives where things get messy: national integrations, moving records through queues reliably, and turning business rules into software that office staff can configure without calling a developer.
I work across PHP (Yii2, Laravel), Java (Spring Boot / Spring Cloud), Python (FastAPI) and Flutter, and I ship everything in Docker.
Admissions, student records, HR, curriculum and e-resource platforms with role-based access, workflows, audit logs and reporting.
REST APIs, an Enterprise Service Bus and national integrations, payment and SMS gateways — secured, logged and monitored.
Spring Cloud services with Eureka, Config Server and Gateway, talking over RabbitMQ, backed by PostgreSQL and MinIO.
Health risk prediction, diabetic-retinopathy screening, LLM-based sentiment analysis and case classification wired into real workflows.
Flutter apps for event scheduling, exam-ticket verification and AGM check-in with QR scanning and offline support.
Dockerised stacks, Nginx, systemd and multi-environment (dev / UAT / prod) configuration for reliable releases.
A selection from 40+ systems — many are internal institutional platforms, so details are summarised rather than linked.
University admissions platform handling applications, multi-round selection and confirmation. Pulls applicant results straight from national bodies to decide eligibility automatically.
Billing platform for a national broadcaster, split into sale, billing, notification, library, audit and reporting services behind a single gateway, with an approval-workflow engine.
Central gateway that every internal system uses to reach external providers. One place to control access, route requests, monitor performance and trace failures.
High-throughput rules service that screens applicants against programme requirements and sorts them into eligible, unqualified and failed — with admin and re-run endpoints.
Staff and student portals for academic records, course registration and administrative processes at university scale, with queued background processing.
Automated screening of diabetic retinopathy from retinal images, with separate flows for non-specialists, specialists and moderators, and PDF reports for patients.
Maternal health risk prediction for hospitals. Clinicians record patients and get model predictions with class probabilities, history and reports.
Runs student course-evaluation comments through a locally hosted LLM to classify sentiment and themes, then presents results in an interactive dashboard and API.
Helps a medicines regulator classify adverse events following immunisation against Brighton Collaboration case definitions, using an LLM to assist reviewers.
Registration, invitation cards, QR check-in, voting and SMS for cooperative annual general meetings — fully configurable by office staff, every change audited.
Modular HRMS covering staff records, contract staff, leave (ruhusa), allowances and leadership, driven by a configurable approval workflow engine.
Web platform and companion Flutter app for an African AI conference: paper submission, speakers, tickets, sessions, surveys, chat and photo galleries.
Headless rebuild of a university website: content managed in Strapi, rendered by a Next.js frontend, deployed with Docker and Nginx.
Mobile app invigilators use to verify students’ exam eligibility on the spot, with local storage for unreliable connectivity.
Manages the full curriculum life cycle — from department proposals through college, university and national approval — as one central repository of approved programmes.
Library platform for e-books, journals and online databases with IP / URL / credential access control, personal collections, storage quotas and a help-desk.
