• Product and platform engineering across events and fairs, with responsibility spanning delivery, performance, experimentation, and production readiness.
• Delivered 20+ product capabilities and led a major initiative from discovery and technical design through launch, collaborating across product, design, and engineering.
• Lowered latency by approximately 50% on heavily used public-facing endpoints, bringing P95, P90, and P75 back within service-level targets.
• Migrated service components from legacy serializers to Active Model Serializers, reducing dependencies and improving maintainability.
• Used Packwerk to define clearer domain and package boundaries in the Rails codebase and improve maintainability.
• Moved selected search endpoints from Elasticsearch to PostgreSQL fuzzy search where PostgreSQL better matched product requirements.
• Strengthened code quality with unit and integration tests, clearer testing boundaries, and code reviews.
• Owned observability for the Berlin team: built Datadog dashboards and ran incident-response training for engineers, improving the team's ability to diagnose and resolve production issues.
• Led engineering setup for high-season A/B experiments testing new approaches to customer acquisition and product adoption.
• Built and maintained payment delivery for Handshake AI Fellows, supporting reliability-sensitive payment workflows with the Handshake AI team.
• Diagnosed and resolved a data inconsistency that had persisted for 2+ years across multiple product areas.

• Diagnosed and resolved critical breakdowns in a live cargo-tracking system serving European logistics vendors.
• Led stakeholder discovery and translated findings into AWS architecture changes and implementation.
• Redesigned services to make them idempotent, resilient to graceful termination, and defensive against incomplete incoming external events, protecting article records from faulty data.
• Implemented asynchronous processing via SQS and workers in ECS to separate message intake from longer processes and to preserve integrity of critical events in the case of service failure.
• Reworked services for horizontal scaling at 5M+ articles/day by tuning ECS resources and autoscaling around queue depth and utilization, improving redundancy, observability, and infrastructure efficiency.

• Designed and delivered the backend and cloud architecture for real-time drone-to-cloud communication, connecting drones and base-station hardware via AWS IoT, Lambda, and DynamoDB.
• Built the operations dashboard and APIs to manage multiple drone operations and control base-station sensors and switches, giving the startup an integrated application for operating its system.
• Owned infrastructure automation and CI/CD for repeatable AWS deployments. Collaborated with a computer-vision engineer on RTSP video integration, owning the application and cloud layers.

Primary freelance engineer for early-stage platforms, owning requirements, architecture, application development, infrastructure, and deployment from proof of concept through MVP delivery.

• Architected and delivered a Flight Automation Center from proof of concept to MVP as the primary engineer, owning frontend, backend services, APIs, and deployment.
• Designed communication between connected flight systems and backend services around a self-hosted MQTT deployment on VPS infrastructure.
• Designed and operated the container platform using Docker, Kubernetes, and Rancher, with Terraform, CI/CD, and Grafana for repeatable environments, deployment, and monitoring.
• Worked directly with stakeholders as requirements evolved, carrying architecture decisions into working software and delivery throughout the engagement.
