Deep expertise in Node.js, Python, MongoDB, and RESTful API development, with hands-on cloud-native infrastructure experience on AWS.

Track record of mentoring engineers and driving architectural decisions across a multi-product portfolio.

Full Stack Engineer - Qimuro TechLab

(2024-01)

• Owned end-to-end delivery of multiple SaaS and enterprise platforms across event management, agriculture, business operations, and digital transformation — the sole or lead engineer taking each product from architecture through production release.
• Led development of QimuroHR, an HR management platform automating attendance tracking, payroll processing, and workflow management, replacing manual processes for client organizations and giving them real-time visibility into their operations.
• Architected EEvOps, a full-featured event-management platform spanning attendee registration, venue booking, exhibitor/sponsor management, floor-plan visualization, payment workflows, notifications, and administrative reporting — designed to support concurrent multi-event, multi-role usage.
• Designed scalable backend services using Node.js, Express.js, MongoDB, Redis, and RabbitMQ, building RESTful APIs engineered to support high-concurrency, multi-user production workloads.
• Built and operated cloud-native infrastructure on AWS, including Dockerized deployments, CI/CD pipelines, SSL/TLS configuration, and Nginx reverse-proxy management — reducing manual deployment steps and improving release reliability.
• Delivered full-stack features across Vue.js and Nuxt.js, shipping responsive, enterprise-grade user experiences for both internal and client-facing applications.
• Spearheaded Shamba Afya, an AI-powered crop-diagnosis platform, taking it from concept to a working product; engineered the Python-based disease-detection model to 95% testing accuracy, directly improving farmers' ability to catch crop disease early.
• Engineered secure, reusable authentication and RBAC infrastructure, plus payment integration, notification services, and third-party API integrations, reused across multiple products to cut duplicate implementation effort.
• Partnered directly with stakeholders, clients, designers, and product teams to translate ambiguous business requirements into scoped, shippable technical solutions.
• Mentored junior developers through the UNDP HACK4ENV program and established engineering best practices and architectural standards adopted company-wide.

Backend Engineer - Nathan Digital

(2024-12 - 2025-06)

• Built and maintained an HRMS platform using Node.js and MongoDB (Mongoose), supporting core HR operations for client organizations.
• Designed RESTful APIs enabling reliable, low-latency communication between front-end and back-end services.
• Drove API quality through systematic testing and debugging with Postman and browser dev tools, reducing integration issues before release.
• Optimized database performance and delivered new system features in close coordination with cross-functional teams, using Git and Bitbucket for version control.
