- Clean, documented source code via Git or ZIP
- Larger projects split into milestone custom offers
How I work:
- Clear scope and price agreed before starting
- Progress updates at key milestones
- Revision rounds defined per package
- 7-day support window after delivery
Please note: custom code only no WordPress, Bubble or no-code builders. Deployment is quoted as a separate service.
Message me with your project goal and I will send you a clear quote.

FAQ
Do you build websites or web applications?
Web applications: systems with login, database and business logic (SaaS, CRM, portals, admin systems). If you need a marketing website or landing page, check my websites gig.
Which stack do you use?
React/Next.js with Tailwind CSS on the frontend; NestJS or Node.js with PostgreSQL or MySQL on the backend. Laravel/PHP and ASP.NET Core are also available.
Can you integrate payments and subscriptions?
Yes: Stripe, PayPal and Wompi, including webhooks and subscription billing. Validated in sandbox first; going live depends on your accounts being ready.
How do milestones work?
For larger projects I send a custom offer split into milestones: you see progress and approve each stage before the next one starts.
How many revision rounds are included?
1 in Basic, 2 in Standard, 3 in Premium. Changes outside the agreed scope are quoted separately.
Can we have a live call?
All communication stays on Fiverr chat. I deliver demos as screen recordings and give updates at key milestones.
