Backend engineer focused on production systems, backend architecture, system design, performance, reliability, authentication, authorization, and billing.
Recently completed a contract where I designed and implemented the backend core of a multi-tenant platform for managing structured UI rules.
- Designed a modular NestJS backend using hexagonal architecture principles
- Implemented organization, brand, and project-level access control
- Built scoped API keys for CLI, MCP, and external API integrations
- Implemented deterministic data processing and transformation
- Developed snapshot versioning, export flows, and Redis infrastructure
- Designed backend architecture and data models from scratch
- Prepared the system for production deployment and external integrations
Previously worked on a core authentication and authorization service used across a product ecosystem.
Key results:
- Reduced database load by approximately 60% using Redis caching
- Improved request latency by approximately 3×
- Performed production data migrations with zero downtime and no user data loss
- Worked with authentication, billing, microservices, and high-risk production changes

- Full-time remote backend roles
- Long-term contracts
- Project-based collaboration
- Backend architecture and system design
- MVP development from architecture to production
For projects with a clearly defined scope, I can take a backend from an idea to a working MVP in approximately six weeks.
