About this gig
Need to connect your web application to third-party services, migrate databases, or build a high-performance custom API?
I am a Key Backend Developer and Database Engineer with 12+ years of experience building integrations for global companies (including Schneider Electric and Bayer AG). I build clean, secure, and fast backend systems.
What I Do:
- 3rd Party API Integrations: Stripe/PayPal, HubSpot, Salesforce, Slack, Twilio, Google Maps, and custom REST/GraphQL APIs.
- Database Engineering: Schema design, optimization, and migration (PostgreSQL, MySQL, MongoDB, DynamoDB).
- Sync & Grabbing Systems: Multi-domain cookie synchronization and guaranteed delivery mechanisms.
- Microservices & Webhooks: High-performance, memory-leak-free Node.js (Express, TypeScript) services.

All code is written to strict industry standards, refactored for performance, and covered with automated tests.
