Experience
Berlin, Germany· PropTech
Engineering ManagerAug 2025 – Present
Team & process: Leading a team of 5+ engineers. Built a strong engineering culture around code ownership, knowledge sharing, and continuous improvement. Introduced quarterly performance reviews, created clarity for underperforming engineers through goals and milestones, and shaped the roadmap to distribute ownership - every engineer can now contribute to any part of the system with minimal onboarding.
Accounting system: Evolved the in-house accounting system from a custom solution into a standardized double-entry ledger - processing 12,000+ bank transactions per month, automatically matching and booking them into the correct accounting entries.
AI DevX: Led AI developer experience across the team - set standards for Claude Code, Cursor, and Codex usage, reducing 2-week projects to 3-4 days while maintaining quality through rigorous code review, unit/integration tests, and Playwright UI tests.
Software Engineering Team LeadSep 2024 – Aug 2025
AI agents: Implemented an agent that automates accounting transaction booking with 90% accuracy (saving 20+ hours/week of manual work) and another that categorizes incoming tickets with 95% accuracy (repair, refund, payment, general).
Search infrastructure: Started as a proof of concept at an offsite using Go and OpenSearch, then after validating with users, rebuilt it into a production-grade search service indexing 7 entity types across 41+ filterable attributes with fuzzy matching and per-company index isolation. Improved query speed by 90% and reduced load on the main database by 70%.
Infrastructure & DevOps: Owned the full deployment pipeline and cloud infrastructure across AWS and Vercel - managed environments, CI/CD workflows, monitoring, and maintaining 99.9% uptime.

Platform rebuild: Joined when the product ran on Airtable as a no-code solution. Played an integral role in rebuilding the entire application on modern technologies - architected the database design (130+ tables), built the backend with NestJS, and contributed significantly to the Next.js frontend serving 300+ employees.
Financial systems: Built the Stripe integration and automated rent-collection workflow from scratch, handling 12,000+ bank transactions per month. Designed and led the in-house accounting system tailored for German property management.
Ticketing system: Built the first version of an in-house ticketing system at an offsite in Portugal - receives notifications via GCP Pub/Sub and processes emails through Gmail API with dedicated processors, auto-linking them to properties and contacts based on sender and context, replacing Outlook and handling 15,000+ emails/month.
