Greenfield platform for the international used-car inspection market. Started as the sole developer, then led two contract developers.

• Delivered three applications in 3 months: an offline-first Flutter mobile application for Android and iOS, a NestJS backend with 134 REST API endpoints and 32 data models, and a Next.js marketplace website with 56 pages
• Built a two-sided marketplace payment system with Stripe Connect escrow, including an 80/20 revenue split, authorize-then-capture flow, payout retries, dispute handling, reconciliation jobs, and DAC7 reporting exports
• Engineered an offline-first data layer for network-independent operation, including schema contract tests enforcing re-sync rules for every table and a local Drift/SQLite database with a 10-step migration path
• Implemented on-device intelligence with Google ML Kit, including vehicle registration document OCR, VIN scanning with ISO 3779 check-digit validation, and on-device PDF report generation with QR codes and signature capture
• Localized the product into 30+ languages, including Chinese, Japanese, and Korean font support for generated PDF documents;
• Secured sensitive KYC identity data using three isolated Cloudflare R2 buckets, a backend upload proxy, pre-signed URLs, and a startup self-check that treats shared storage as a fatal production configuration error
• Authored an 8-document technical specification package for a non-technical client and secured approval before development began
• Participated across the full product lifecycle, from requirements and architecture through development, deployment, release management, and production operations

Complete platform rebuild for an established real estate agency. Owned the API, data model, CRM integration, and delivery infrastructure.

• Protected organic search traffic during the rebuild by developing a reverse SEO matching engine for 2,604 legacy landing URLs and a byte-exact regression gate covering 1,784 of 2,466 URLs (72%), with versioned gap reports for remaining differences
• Resolved a production HTTP 504 timeout in the search API by replacing a correlated subquery scanning 536,000 rows per candidate with a batch-based query strategy
• Owned the delivery infrastructure, including Docker Compose environments, Bitbucket Pipelines CI/CD with a 30-poll health-check gate, Linux hosting on Hetzner, startup-time Zod environment validation, and transactional environment-to-environment database synchronization with backup safeguards
