02 / Selected projects & achievements
First team-owned, fully independent microservice
EcoVadisArchitected and led development of the service connecting users of monolithic legacy applications (backoffice and the main SaaS product) with a new Tableau-based BI solution — battle-testing the organisation’s replatforming effort and setting the pattern for autonomous, resilient services.
RBAC access-control platform (ACL)
EcoVadisCo-architected and built a role-based access control solution flexible enough to model access across current and planned products, under rigorous performance requirements, with an automated path for other teams to protect their own resources.
Modular multi-tenant patient portal
LUX MEDCo-architected (owning technical architecture) and led development of the portal that moved new-patient data handling from manual work by LUX MED staff to clients’ HR departments and, later, the employees themselves. It halted headcount growth in customer service and became a main selling point in contract renegotiations and new-client acquisition.
Platform modernisation & event-driven rearchitecture
LUX MEDLed evaluation and rollout of the move from WCF/ExtJS to ASP.NET Core, .NET Core, RabbitMQ, Hangfire and Angular 4+, with independent vertically-sliced services connected by events — from development practices to operations and CI/CD. Also built culture: knowledge-sharing, documenting in public, planning for failure, safe-to-fail teams.

Pixelated MilkCo-designed and built locations, travel, quest, banter, time-flow, NPC scheduling, requirements, crafting, shopping, party, notification and loot modules — each with authoring tools so designers and testers could build the game world without developer support.
