Projekthistorie
Lead development and end-to-end ownership of customer-facing product surfaces across frontend, backend, data, asynchronous processing, releases, and production support in a healthcare technology environment. Contributed to Jesse, AIOS's agentic AI system for automating operational workflows such as orders, sales, and referrals, using agent-oriented workflows and Langfuse-backed AI observability. Led end-to-end development of a customer marketplace enabling patients to select pharmacies, browse product variants, upload prescriptions, and complete purchases through integrated checkout and payment flows. Designed and delivered billing workflows from the ground up, including care-team billing tickets and automated flows for failed payments and enrollment-driven cases. Strengthened the platform's multi-tenant architecture by implementing organization-aware dynamic theming.
Spearheaded a permission-based sharing system for jobs, candidates, companies, and documents, introducing granular access controls. Built a configurable CV-generation experience with reusable templates, real-time candidate data editing, live preview, and PDF export. Implemented asynchronous campaign and document-generation workflows with BullMQ and polling. Automated frontend/backend version-consistency checks through GitHub Actions. Developed document-generation capabilities for PDF, CSV, and TXT outputs. Improved release confidence through Jest unit tests, Cypress end-to-end/smoke coverage, code reviews, and production-readiness QA.
Delivered full-stack healthcare product features using React, Next.js, TypeScript, GraphQL, NestJS, Prisma, and PostgreSQL. Led responsive-design improvements across application surfaces. Implemented two-factor authentication. Improved application reliability through Jest unit testing and Cypress end-to-end coverage. Participated actively in code reviews and technical delivery in an Agile environment. Led and mentored a team of interns, conducting stand-ups, supporting task execution, and helping engineers develop their technical skills.
