What technologies do I work with?
I mainly work with Next.js, React, TypeScript, JavaScript, PHP, Node.js, Express, MySQL, Supabase, MongoDB, Convex, PostgreSQL, Stripe, Paystack, Resend, PHPMailer, Nodemailer, Vercel, Namecheap, cPanel, Cloudflare, and GitHub Actions.
Can I fix deployment, domain, or DNS issues?
Yes. I can help with Vercel deployment, Namecheap/cPanel hosting, Cloudflare DNS, subdomains, CNAME/A/TXT records, SSL issues, environment variables, local-vs-production problems, and production configuration errors.
Can I work on an unfinished web app?
Yes. I can review an unfinished app, identify what is missing or broken, and help complete the needed parts. This may include frontend pages, backend logic, APIs, database flow, authentication, payments, email, deployment, or dashboard features.
What do I need from you to start?
I need a clear explanation of the issue, screenshots or error messages if available, your project link or repository access, and details of what you expect the final result to do. For deployment or DNS issues, I may also need access to your hosting, domain, or deployment platform.
Will I add new features or only fix bugs
This gig is mainly for bug fixing, app completion, integration, and deployment support. Small feature fixes may fit within the package, but larger new features should be discussed first so I can confirm the correct scope and price.
Can I work with private or sensitive projects?
Yes. I can work with private projects, but please do not send passwords, API keys, or secrets directly in chat. Use secure access methods where possible, and only share the minimum access needed for the task.
What if the issue is bigger than expected?
If I find that the issue is larger than the selected package, I will explain the problem clearly before continuing. We can adjust the scope, create an extra, or agree on the best next step.
Do you provide documentation after fixing the issue?
Yes. I provide a brief explanation of what was fixed. Standard and Premium packages can include more detailed notes, code comments, or setup guidance depending on the issue.
