Hello, Ivan! The implementation of the API for the "Borovoe" system is an important step towards improving the user experience. I specialize in integrating cryptographically secure APIs with external systems, ensuring flawless data exchange. My deep knowledge of Go-lang and skills in server configuration guarantee optimal service performance even under high loads. I am confident that together we can achieve a high level of automation and accounting. I would be happy to share my experience in creating scalable solutions for the successful completion of your project. Let's discuss your tasks in detail!

Hello Ivan.
I checked out your Go project, API docs, sql DB and Integration guide for the Borovoye automated process control system.
I’ll:
Build ticket fetch/placement service via API to Rekassa (ID/token auth, intermediate storage).
Handle turnstile queries + secure access validation.
Implement report exports (CSV/PDF) to org endpoints.
Go modules, concurrent-safe, Docker-ready for your server.
Feel free contact with me.
Thanks.

Hey Ivan,
I've reviewed your Borovoe ticketing system documentation. Your Go server structure is clean, and I see exactly what needs to be done - integrate Rekassa API, handle ticket storage, and ensure turnstiles get proper access validation.
Why this will work with me:
I've dealt with access control systems before. The critical part isn't just receiving tickets from Rekassa - it's handling the edge cases when turnstiles lose connection, duplicate webhook calls arrive, or MySQL replication lags. Your Z5R-W controllers need bulletproof offline mode, and I know how to implement proper event sourcing so no access event gets lost.
Looking at your database schema, the abonements_created and events tables are straightforward, but I'll add proper indexing on card and controller_sn fields for faster lookups when you scale to thousands of daily entries. The check_access flow through Cloud to turnstiles needs careful timeout handling - nobody wants tourists stuck at the gate.
What I'll deliver:
Working Rekassa integration in your existing Go codebase, not a rewrite. Proper buffering for offline scenarios. Clean reporting module that actually shows meaningful data, not just raw database dumps. Everything tested on both testnet and production scenarios.
Timeline: 5-7 days for core integration, another 3 days for reports and testing. $400 total.
I run production systems myself, so I understand that "working" means handling real-world chaos, not just happy-path scenarios. Ready to start immediately.
Let's make those turnstiles work smoothly.

Good day!
I have reviewed the archive with the server — the structure is clear, the backend in Go is already prepared for extensions, there are separate modules for the API, equipment, and reports.
I can implement the full integration with Rekassa:
• obtaining tickets through their API
• placing tickets on our intermediate server
• implementing access logic for the turnstile
• generating and sending reports to the relevant organization
• testing the entire cycle: “Rekassa → our server → turnstile”
Estimated cost: 15,000 – 25,000 UAH
Timeline: 6–12 working days
(I will provide a more accurate estimate after receiving the technical requirements for the reports)
Thank you for providing the archive — I am ready to start after clarifying the details.

Hello,
The service will be developed in Go using the Gin framework and deployed on Ubuntu 22.04. Gin is chosen for its high performance, minimal overhead, and robust support for JSON-based REST APIs, which fits perfectly with the requirements of HTTP POST communication with Rekassa and internal APIs. The service will interact with MySQL 5.7/8.0 for storing tickets and event logs. Offline operation will be supported with local buffering and automatic retry for failed API requests. Security will be ensured through HTTPS for all communications.
The project will follow a phased approach:
Analyze requirements and design the data flow from ticket purchase to access verification.
Develop the backend service in Go using Gin to handle ticket intake, validation, and storage in the database.
Integrate with the Z5R-W server for real-time access control, returning granted or denied status.
Implement automated reporting and event logging for SAK and organizational reporting.
Conduct testing and deploy the solution on Ubuntu with backup, monitoring, and retry mechanisms.
This approach ensures a reliable, maintainable, and scalable system that meets all technical and operational requirements. The use of Gin guarantees high performance and efficient handling of concurrent requests, which is critical for access control and ticket processing workflows.
Sincerely,
Jeo Vincent Carretas
