1. Jun 2024 — Present

   Software Engineer Assistant · Cytonn Investments

   • Build and maintain backend systems and RESTful APIs for enterprise financial platforms in Laravel, with Filament and Livewire admin interfaces.
   • Refactored database queries and backend logic, improving performance and reducing technical debt; wrote unit and integration tests to strengthen release confidence.
   • Delivered Vue.js/Tailwind interfaces and Angular admin interfaces for CRIMS, a portfolio management platform.

   Key project: e-Float — Multi-tenant petty cash & disbursement platform

   • Architected a three-system payment pipeline: async AMQP messaging with the core investment platform plus an OAuth2 HTTP integration for M-Pesa and bank payouts, with correlation-ID tracing across all three.
   • Built idempotent notification and deposit handling with redemption reversal on terminal failure, so retries and polling never double-credit or double-pay.
   • Delivered tiered multi-stage approvals, SSO-backed RBAC with per-client access grants, and an append-only audit log.
   • Built bulk payments from CSV/XLSX with all-or-nothing pre-validation; fixed a thousands-separator parsing bug that would have paid 1/1000th of the intended amount.
   • Shipped with 473 automated tests across 84 files, verified end-to-end against a live message broker and payments instance.

   Key project: Cytrello — Internal workspace & task management platform

   • Owned end-to-end design and delivery of a multi-tenant task platform used across departments.
   • Built a recurring-task engine with scheduled jobs that generate, reset and reassign cards on hourly to monthly cycles.
   • Architected a cross-workspace sync service that mirrors cards bidirectionally in real time, with configurable column mapping.
   • Implemented granular RBAC separating board membership from task-level access for confidential client collaboration.
