Lina Montano
À propos de ce service
Need a REST API that actually works in production?
I'm a backend developer with 6+ years building APIs for large-scale e-commerce and government platforms in Latin America. I write clean, documented code your team can maintain after delivery.
WHAT I BUILD
- REST APIs in Python, Node js and Go
- Third-party integrations such as payments, CRM and messaging
- Database design in PostgreSQL, MySQL and MongoDB
- JWT and role-based authentication
- Automation scripts and data processing
- Cloud deployment on AWS and GCP
WHAT YOU GET
- Full source code, yours to keep
- Postman collection to test every endpoint
- Clear technical documentation
- Secure, scalable architecture, not a quick hack
WHY ME
I work as a backend developer at a leading Latin American e-commerce company, building high-availability APIs and security systems. I'm also a Google Women Techmakers Ambassador and a tech community leader in Medellín, Colombia.
Message me before ordering with your project details so I can confirm scope and timeline. I reply fast and work in English and Spanish.

FAQ
What information do you need to start?
Send me your project goal, the endpoints or integrations you need, your preferred language if you have one, and any existing documentation or database schema. If you're not sure what you need, just describe the problem and I'll suggest the scope.
Do I own the code?
Yes. You receive the full source code and complete ownership once the order is delivered. No hidden licenses, no dependencies on me to keep it running.
Which languages and frameworks do you work with?
Python, Node js and Go for the backend, with PostgreSQL, MySQL, MongoDB or SQL Server for data. I deploy on AWS and GCP. If your project already uses a specific stack, tell me and I'll confirm the fit before you order.
Do you build frontend or design websites?
My main focus is backend, but I can build the frontend as a paid add-on using React or Vue. I take on interfaces that connect to the API I build for you, such as admin dashboards or internal tools. I don't take standalone frontend projects and I don't do UI or graphic design.
What if my project is bigger than the Premium package?
Message me with the details and I'll send you a custom offer. Large projects are better handled in phases, so we can start with a defined first stage and continue from there.
Do you offer support after delivery?
Yes, I fix any bug related to my code at no cost for 14 days after delivery. Ongoing maintenance or new features can be arranged as a separate order.
Can you work with my existing codebase?
Yes. Send me the repository or a description of the current stack and I'll review it before we start. Working with existing code usually needs a short assessment first, so message me before ordering.
How do you handle my credentials and sensitive data?
I only ask for the minimum access needed and I work with environment variables and secure credential handling. My background includes security auditing and access control systems, so this is part of how I build, not an afterthought.
