Digitalization and automation of land administration business processes through BPMN workflow modeling and GIS integration

• Worked within an Nx monorepo architecture comprising two interconnected applications and two shared libraries, improving code reuse and maintainability across the platform
• Developed and maintained a component library with Storybook, creating 30+ reusable components that reduced feature development time by 35% and ensured 95% design consistency across applications.
• Built a web application for land-administration workflow management, implementing complex BPMN-based processes, which accelerated task routing and reduced processing delays
• Built a Camunda abstraction library that decoupled business logic from workflow engine implementation, enabling code reuse across applications, and seamless future engine upgrades without major refactoring
• Modeled 15 land administration business processes using BPMN, automating workflows and reducing manual processing time from 7 days to 48 hours.
• Integrated Geographic Information System (GIS) components for spatial data visualization and land-parcel management, enabling users to view and edit parcel boundaries directly within the platform

Development of a FHIR standard-compliant EMR, ensuring interoperability between health information systems while mentoring developers.

• Development of an EMR (Electronic Medical Record) system using Angular and Tailwind, designed to manage 3,000+ patient records and support 100 healthcare professionals across 3 facilities.
• Designed and implemented FHIR data exchange architecture with custom facade supporting 3 FHIR resource types (Patient, Observation, and Encounter), interoperability with 2 external health information systems at 95% data accuracy.
• Mentored 2 developers (junior mobile, mid-level web) through code reviews and pair programming, accelerating their autonomous delivery by 60% within 3 months.
• Optimized the software development lifecycle by introducing best practices, code reviews, and streamlined deployment processes, resulting in faster release cycles and fewer defects

Technical leadership and architecture design for the Logika project, managing a team of 3 developers (1 mid-level backend, 2 junior frontend)

• Defined the complete technology stack (Angular, Node.js, MongoDB) and designed a monolithic architecture that met project requirements, enabling a unified codebase and simplifying integration across teams
• Established development standards and workflows: initialized project structure, implemented Git branching strategy, and set up CI/CD pipelines to ensure consistent code quality
• Built technical documentation foundation using Docusaurus, creating a knowledge base for onboarding and maintaining development best practices
• Mentored 2 junior frontend developers through code reviews and pair programming, reducing their PR turnaround time by 50% and enabling independent feature delivery within 2 months
• Provided ongoing technical support and architectural guidance to ensure team alignment and project delivery

Integrated DevOps practices into the development lifecycle, focusing on Infrastructure as Code (IaC), CI/CD automation, and proactive monitoring.

• Automated deployment workflows using IaC and CI/CD pipelines, which accelerated deployment frequency by 60% within four months.
• Enhanced system reliability by implementing full-stack monitoring and alerting solutions, reducing unplanned downtime by 30% in two months.

Architectural refactoring and route optimization for Logidoo, a cross-border logistics platform serving African trade routes

• Migrated the monolithic Express.js application to three independent NestJS microservices, cutting deployment coupling by 80% and lowering API response time from 750 ms to 320 ms
• Implemented Dijkstra's algorithm to calculate and compare optimal shipping routes, enabling customers to select between the most cost-effective or fastest option across 8 African countries

Development and refactoring of a multi-site management platform for an expanding bakery (Angular, Ionic, ExpressJS, MongoDB) Within a team of 3 developers, I evolved from a mobile developer role to full-stack responsibilities as the project grew:

• Developed the mobile application with Ionic and Angular for daily bakery management, enabling over 100 users to perform tasks
• Orchestrated data migration of 50,000+ records during expansion to 3 new sites: designed and implemented an ETL pipeline using Apache NiFi and Python scripts to ensure multi-site data consistency with 80% data integrity
• Refactored the backend and frontend to support a multi-site architecture, enhancing system scalability and maintainability
• Designed and implemented a data exchange architecture to synchronize transactions with an external Point of Sale and achieved 99% sync accuracy
