- External API integrations
- Business logic and data processing
- Error handling and validation
- Automated tests
- Docker deployment
TECH STACK:
Python, FastAPI, PostgreSQL, Redis, Docker, REST APIs, WebSockets.
WHY WORK WITH ME:
- 12+ years in software engineering
- Founder and CTO of Ronin Systems
- Strong background in backend architecture and system reliability

Founder and CTO of Ronin Systems. 12+ years in software engineering and architecture. Previously led SDET teams in large financial and high-traffic technology companies, where a defect costs money directly.
I own the technical outcome, not one language. I scope the problem, design the system, then build it on the stack that fits.
Backend, APIs, chatbots, AI integrations, automation and real-time services. Mainly Python and TypeScript/Node; recent public work shipped in Rust/WebAssembly.
You get defined scope before code, progress you can see, and documented source at the end.
FAQ
What is included in the Basic package?
The Basic package includes a small FastAPI backend with up to 3 REST API endpoints and source code. Database integration, authentication, deployment, and advanced integrations are not included.
What counts as one API endpoint?
One endpoint is one API operation, such as creating, retrieving, updating, or deleting data.
Can you connect the backend to my existing frontend or mobile app?
Yes. I can build REST APIs for React, Vue, Next.js, mobile apps, Telegram Mini Apps, and other clients.
Do you provide database integration?
Yes. PostgreSQL database integration is included in higher packages or can be added as an extra where available.
Can you add authentication?
Yes. JWT authentication, protected routes, and role-based access can be included in larger packages or custom offers.
Can you integrate third-party APIs or services?
Yes. I can connect documented REST APIs, payment systems, CRMs, analytics services, and other external platforms.
Will I receive the source code?
Yes. Source code is included in every package.
Do you deploy the backend to a server?
Deployment is available as an extra. I can deploy the project on one VPS using Docker and configure automatic restart.
What is considered a revision?
A revision is a correction within the originally agreed scope. New endpoints, integrations, features, or architecture changes are additional work.
What if my project does not fit the packages?
I can provide a custom offer based on the required endpoints, integrations, database structure, and deployment needs.
