Where I've shipped

04 ROLES

01.2023–now

PCG GmbH

Architected a multi-tenant customer data platform serving ~250 enterprise accounts; designed cross-account AWS state mirroring with cached security-group snapshots to maintain read consistency under API rate limits, eliminating service failures caused by AWS API throttling.
Led full system rebuild of a B2C creator platform with a 12-person team over 12 months; defined service boundaries, data ownership contracts, and rollout strategy for a system that scaled to 25,000 registered users and 100 creators.
Designed an idempotent token-ledger and referral-attribution system with exactly-once credit semantics, preventing double-spend and ensuring auditable revenue attribution across asynchronous settlement flows.
Took full systems ownership of a stalled sustainability-reporting product mid-delivery, re-established delivery confidence, and shipped to 350 enterprise customers.
Defined and enforced the engineering hiring bar as technical evaluator across 3 hiring rounds; standardised system-design and distributed-systems assessment criteria.

01.2022–01.2023

Devoteam GmbH

Designed and implemented 4 microservices for a meter-collection and analytics platform serving utility field employees; established service contracts and fault-isolation boundaries between collection, processing, and reporting tiers.
Built interpolation and anomaly-detection pipelines for real-time utility data, including pipeline-leak identification; applied backpressure-aware processing to handle uneven ingestion rates from distributed field sensors.
Coordinated integration across a 6-person cross-functional team (2 frontend, 3 backend, 1 data), resolving systemic consistency failures between pipeline stages and unblocking delivery.
Mentored a junior colleague through technical growth, directly contributing to her promotion to senior role.

01.2020–01.2022

code'n'ground AG

Primary developer on a DiGA-certified snoring-therapy app requiring deterministic, reproducible exercise state across 49 exercises and a 3-month program — correctness guarantees mandated by medical certification; shipped to 200,000+ users.
Translated a clinical scheduling algorithm into conflict-free deterministic logic with prerequisite-gated progression and category isolation across motor, holding, and utensil-based exercise tracks.
Built a configurable emotion-recognition assessment tool for University of Ulm psychology researchers with automated, reproducible reporting — reproducible configuration model enabled Phase 2 expansion.
Introduced Angular as the company's first SPA framework, migrating 2 client projects off legacy jQuery/CodeIgniter to component-driven architecture.
Developed a waste-disposal marketplace matching companies with certified disposers for regulated waste categories, enforcing compliance routing logic at the matching layer.

01.2019–01.2020

code'n'ground AG

Completed an intensive software engineering curriculum covering full-stack web development including JavaScript, PHP, and React.
Took ownership of a multi-tenant e-commerce platform through initial implementation and ongoing maintenance — first exposure to shared-state isolation across tenant boundaries.
Built a planting machine configurator enabling modular equipment assembly from validated compatible components.
