Architecture Governance
Represented my department in freenet's internal Architecture Management Group, contributing to company-wide architecture decisions and technical standards.
Backend / Cloud Software Developer
Backend systems, owned from architecture to handover.
I design cloud backends and turn architecture into executable work. My recent work spans company-wide architecture governance, the first Backend for Frontend at freenet, AWS serverless systems, and central Auth0/IAM services.
Based in Calgary, AB, with a Canadian IEC open work permit. Available now, no sponsorship or LMIA required.
Work focus
Architecture that teams can deliver and own.
My responsibility extends beyond implementation: architecture, technical documentation, governance review, planning, cross-team coordination, production readiness, and knowledge transfer.
BFF Delivery & Handover
Owned freenet's first Backend for Frontend from architecture and governance review through Jira planning, cross-team delivery, and structured knowledge transfer.
Reliable Backend Operations
Build and maintain AWS services, APIs, identity boundaries, observability, security controls, and delivery workflows for production ownership.
Achievements
Ownership beyond implementation.
Architecture Governance
Nominated to represent my department in the internal Architecture Management Group, where system architects and selected engineering representatives align company-wide standards and decisions.
First Backend for Frontend
Owned architecture, documentation, governance review, implementation planning, task breakdown, dependencies, and handover for the company's first BFF.
IAM Platform Ownership
Developed and maintained central Auth0-based customer login and authorization services used by multiple internal teams across freenet Mobilfunk and Klarmobil.
Cloud Infrastructure Delivery
Developed and operated serverless AWS services with IaC, scalable architectures, observability, and Glue-based data pipelines across a 3-year tenure at Fielmann.
Cross-Team Enablement
Turned architecture into executable work, coordinated dependencies and Product Owner alignment, and enabled a frontend-focused team to maintain the BFF independently after handover.
AI-Assisted Engineering
Use AI to accelerate analysis, implementation, and debugging while retaining responsibility for correctness, architecture, maintainability, security, and long-term fit.
Selected Engineering Patterns
Selected architecture and backend case studies.
These examples show where I owned delivery and where I contributed inside team-built systems, without exposing private source code or internal project material.
Backend work made tangible
API contracts, consent gates, private connectivity, event flows, canaries, and reliability controls are the visible artifacts of systems that otherwise live behind the scenes.
First Backend for Frontend
A new backend boundary for a frontend-focused team with limited AWS experience, designed to fit internal architecture standards and remain maintainable after handover.

Experience
Six years of shipping software, nearly four full-time.
From internal tooling to AWS platforms, architecture governance, and end-to-end BFF delivery — with increasing ownership across systems and teams.
