About this gig
Are you building a Fintech platform or a complex Enterprise SaaS? You dont just need a coder; you need a System Architect.
I am a Senior Software Engineer specializing in high-security, production-ready backends. I recently architected a complete Multi-Tenant Core Banking SaaS from scratch, featuring a custom double-entry ledger and atomic transaction processing.
What I bring to your project:
- Data Integrity: Implementation of strict financial logic, ensuring assets and liabilities always balance.
- Security-First Design: Role-Based Access Control (RBAC), JWT authentication, and protection against high-concurrency race conditions using row-locking.
- Scalable Architecture: Multi-tenant database design optimized for high-volume PostgreSQL queries.
- DevOps Ready: Clean, documented code ready for Docker containerization and CI/CD deployment.
Technical Expertise:
Python (Django / DRF), PostgreSQL (JSONB), Redis, Celery, Docker, Sentry.
I focus on clean code (PEP8), high performance, and meeting strict deadlines.
NOTE: Please contact me before placing an order to discuss your specific architectural requirements. Lets build something robust.

FAQ
Do you provide API documentation?
Yes, all backends I build include auto-generated, interactive documentation using Swagger/OpenAPI (drf-spectacular), making frontend integration seamless.
Can you handle complex financial math?
Absolutely. I specialize in straight-line amortization logic, interest calculation engines, and double-entry general ledgers where data integrity is non-negotiable.
Will you handle the deployment?
My premium package includes setting up your production environment on DigitalOcean or AWS using Docker, Nginx, and SSL configuration.
