Do you need a reliable Yii2 developer to fix bugs, add features, or build a robust web app end-to-end? I specialize in Yii2 (Basic & Advanced templates) with production experience across SaaS, CRMs, school/HR systems, ticketing, and secure portals.
What I can do for you

- Custom modules (CRUD, dashboards, reports, PDF/Excel export)
- APIs & integrations (REST/JWT, payments, SMS/email, webhooks)
- Database design & migrations (MySQL/MariaDB/PostgreSQL)
- Auth & security (RBAC/roles/permissions, rate limits, CSRF, headers)
- Performance (caching, query tuning, async jobs/queues)
- UI (Bootstrap 4/5, AdminLTE, responsive layouts)
- DevOps help (env setup, Nginx/Apache, .env, build/deploy notes)
Why work with me
- Clean, testable code following Yii2 best practices

FAQ
Do you work with both Basic and Advanced templates?
Yes. I’m fluent in both, including custom module layouts, RBAC, and multi-env configs
Can you upgrade my project to PHP 8.x or newer Yii2 releases?
Absolutely. I audit composer deps, replace deprecated APIs, run tests, and provide a safe upgrade plan.
Will you set up role-based access (RBAC)?
Yes—roles, permissions, rules, and migrations, plus examples to extend later.
Do you provide API development?
Yes—RESTful endpoints, authentication (Bearer/JWT), rate-limiting, and OpenAPI/Swagger docs if needed.
How do you deliver changes?
Preferably via Git (branch + PR). If you don’t use Git, I can ship a versioned zip with instructions.
