Work

Owned the architecture of the central registry that banks report credit data to, then migrated it off Visual Basic. Defined the stack for its successor, which carries five times the data complexity, and moved the bank's delivery pipeline from TFS to Azure DevOps.

Migrated a 1994-era track-and-trace system to modern .NET while keeping its Oracle schemas intact. Connected the operator to the Universal Postal Union network in four months, and built live monitoring for 60 Oracle databases across the country.

Ran the old and new applications side by side behind YARP so users never saw the switch. Built one shared UI layer that both versions use, added Redis caching across the hybrid setup, and ran a measured pilot of AI-assisted development.

Owned the OAuth2 and OpenID Connect architecture for a clinical communication platform, built care-team administration across microservices and real-time clinical alerting, and led the engineering team through a move to Clean Architecture and CQRS on Azure.

Retrieval-augmented generation over regulatory datasets, using Azure OpenAI embeddings and Elasticsearch inside a platform firms use to monitor employee trading. Internal APIs exposed as MCP tools so AI agents can use them safely.

An application-management platform powering a national e-services portal, an HR and finance system for public administration, portals for government institutions, and a number-portability platform for the country's telecom operators.

Led a unit of 10–15 engineers delivering enterprise portals and large public-sector platforms, owning architecture and engineering standards.

Led 12 developers, as interim CTO, building a modular enterprise suite that runs a multi-tenant corporate building, plus internal tools used by the CEO and board.

Led the migration of a marketing platform's micro-frontends from Blazor to React, with Azure Functions and an enterprise service bus behind it.

Built the automation framework from scratch and led the QA team: test plans, automated suites in Java with Serenity BDD, and tools that developers and testers both used.

Evaluation datasets, regression checks and edge cases for AI and machine-learning features, run against every model and prompt change. Playwright automation for the critical web flows around them.

Behaviour-driven test suites in Java with Cucumber, plus load and stress testing with NeoLoad and Gatling. Built an internal browser extension so developers could flag changed pages and QA could plan around them.

Automated checks for business-critical logistics workflows, covering real-time messaging, race conditions and failure handling across Kubernetes environments.
