Leading the design and delivery of production systems, primarily in Go and Vue 3 / TypeScript:

• Investment club management platform (multi-tenant SaaS, in development): Designed and built a Go backend (Chi, PostgreSQL, sqlc, Redis) and Vue 3 + TypeScript frontend featuring a double-entry ledger with unit / NAV accounting, contributions, loan management with amortisation and portfolio-at-risk tracking, member distributions, an investment-portfolio module, and a provider-agnostic payments pipeline integrating mobile money and cash. Engineered platform-wide controls — role-based access with PostgreSQL row-level security for tenant isolation, maker-checker approvals, multi-factor authentication and per-transaction OTP, an event-driven outbox with idempotency, and PDF / CSV reporting — built for compliance with Uganda's Data Protection Act (2019) and verified by a full browser-to-API end-to-end test suite.
• Management information system for facility administration (demonstration platform): Architected and built an MIS delivered as ~18 Go microservices behind an authentication gateway with a Vue single-page frontend. Implemented multi-tenant facility portals (per-facility subdomains), single sign-on via ZITADEL with LDAP, and fingerprint / biometric (ABIS) integration; deployed on Kubernetes (RKE2) with wildcard TLS.
• National Education Management Information System — EMIS 2.0 (rebuild): Contributed to re-architecting Uganda's national EMIS as an event-driven microservices platform. Developed backend services in Go and PHP / Laravel spanning authentication and authorisation (Keycloak SSO with hierarchical RBAC and ABAC), person identity (where I led the Go rewrite, including deduplication and external verification), integrations with external government systems (NIRA, national examination bodies), institutional application and approval workflows, multi-channel notifications, file management (MinIO), and a tamper-evident, hash-chained audit trail. Built the Schools, Ministry and Local Government frontend portals in Vue 3 / TypeScript on a shared base UI (Shadcn Vue, Tailwind), backed by PostgreSQL, Redis, RabbitMQ and Kafka.
• Residential & community management platform (multi-tenant): Built a platform spanning an API, resident and community web applications, an administrative control panel, and a mobile client.

• Led the technical team for the Ministry of Foreign Affairs Integrated System, developing a shared design library for a consistent design language across the system's portals.
• As UI Developer on the Malawi-CFTC project, established the frontend environment (TypeScript, Vue.js, Tailwind CSS), set up CI/CD pipelines, and integrated the UI with the API.
• Developed and maintained seven portals integrated with backend APIs, contributed to the Online Business Registration System, participated in client requirements meetings, and mentored a junior frontend engineer.

• Led a team designing, developing and maintaining the National Education Management Information System (EMIS) for Uganda's Ministry of Education, using Laravel and Vue.js.
• The system tracks stakeholders across the education sector, monitors learners, automates HR recruitment, postings and transfers, and manages licensing and registration of private institutions — integrating data from NIRA and UNEB.
• Mentored junior PHP / Laravel developers, supported User Acceptance Testing, and facilitated stakeholder training within the Ministry.

• Designed and developed additional features for the Board's web application using Laravel, and trained board staff on the new functionality. (A follow-up to the earlier ARB engagement below.)

• Designed and deployed the ARB website and an online form-submission system that digitised architects' project submissions for regulatory review by the Board. Trained staff and provided IT support.

• Led a team to build a Laravel-based financial system that automated the disbursement of volunteer incentives, cutting processing time by over half through SMS and Mobile Money integration. Trained volunteers and staff and provided IT support.

• Designed and deployed information websites, including a content-management system enabling The Collective UG to publish and offer music albums to the public.
