FAQ
Do you provide source code?
Yes, source code is included in all packages. For BASIC and STANDARD, code is clean but with basic comments. PREMIUM includes detailed comments and a deployment guide.
Can you work with my existing code or design?
Absolutely. I can integrate with your existing codebase, follow your design specifications, or build from scratch – whichever you prefer.
What about revisions?
Each package includes a set number of revisions (1 for BASIC, 2 for STANDARD, 3 for PREMIUM). Additional revisions can be purchased as an extra service.
Do you support real-time communication (TCP/IP, WebSocket)?
Yes, I have strong experience with TCP/IP socket programming (both client and server) and WebSocket. I can implement custom protocols or use standard ones like HTTP/REST.
Can you help with IoT projects (connect desktop app to cloud devices)?
Definitely. I have built IoT solutions where Qt desktop apps communicate with MCU boards and cloud servers (e.g., coffee machine remote control). I can work with MQTT, HTTP APIs, or raw TCP.
What files will you deliver?
Source code (Git repo or zip), compiled executable (if requested), a short README with build/run instructions, and for PREMIUM – a deployment guide.
Do you offer support after delivery?
Basic support (questions about the delivered code) is free for 7 days after delivery. Extended support or bug fixes can be arranged via a separate order.
What is your typical response time?
I usually reply within a few hours (max 24 hours). Feel free to message me anytime.
