FAQ
What do you need from me to get started?
A short description of what you want the script or system to do, any API documentation or website URLs, and example input/output data if available. If deployment is needed, I may also request server access or a test environment.
Can you deploy the project to my server or hosting?
Yes. I can deploy to Linux servers (VPS or cloud), configure NGINX, create systemd services, set up SSL, configure environment variables, and prepare a Docker setup if needed.
Do you work with private APIs or authenticated websites?
Yes, as long as you legally own access or have permission to use the service. I do not bypass authentication or access data illegally.
Will I get full source code?
Yes. Every project includes complete source code, project structure, and instructions for running and maintaining it.
Can you make the bot, API, or script run automatically on a schedule?
Absolutely. I can set up cron jobs, background workers, or a task queue (Celery / RQ) to run tasks hourly, daily, or triggered by events.
Can you integrate the project with my existing database or system?
Yes. I work with PostgreSQL, MySQL, SQLite, Redis, and can integrate with CRMs, dashboards, internal APIs, or 3rd-party services.
Do you provide documentation or instructions?
Yes. I always include a README with setup steps, environment variables, and usage examples. For larger projects, I can also include architecture notes.
Will the script or API be scalable for future features?
Yes. I focus on clean and modular architecture, so your system can grow without rewriting everything later.
Do you offer ongoing support or maintenance?
Yes. I can provide support after delivery or create a maintenance agreement if you need continuous updates or monitoring.
What if I’m not technical?
No problem. I will explain everything in simple language and deliver solutions that are easy to use, even without technical knowledge.
