I work with React, Next.js, TypeScript, Node.js, NestJS and PostgreSQL.
Choose the scope that fits:
BASIC: One simple module, up to 3 screens.
STANDARD: Two connected modules and a dashboard, up to 6 screens.

Every package includes login, a database, responsive design, source code and comments explaining key logic. I test the agreed workflows before delivery.
Subscriptions, separate company accounts, integrations and data migration require a custom quote. Hosting and paid services are agreed separately.
Message me on Fiverr with your workflow, required features and deadline so we can confirm the right scope before you order.

I build custom ERP, CRM, and inventory systems for businesses losing money to poor tracking, missing stock, and cash leakage. I’m a full-stack developer: I design the interface, build the backend, and ship something your team can use daily. That includes stock tracking, sales records, customer management, and clear dashboards. If you still run on notebooks and WhatsApp, I’ll turn that into a system that shows where the money and stock go.

FAQ
What types of applications can you build?
I build custom ERP, CRM, inventory, retail management and SaaS web applications. Features are selected around your workflow and the agreed package scope.
Should I contact you before ordering?
Yes. Send your business workflow, required features, user types and target deadline through Fiverr. I will help confirm the right package and scope before you order.
What is a module, and how are pages counted?
A module is a business function, such as customer management or stock tracking. Pages are distinct application screens. Login pages and dashboards count toward your package's screen limit.
Will I receive the source code?
Yes. Every package includes the source code for the delivered application and comments explaining key logic. We will confirm any third-party dependencies during project planning.
Are hosting and deployment included?
Hosting, domains and paid third-party services are separate costs. We agree on the hosting environment and any deployment assistance before the order begins.
Can you add payments, subscriptions or import my data?
These can be assessed for a custom quote. Payment integrations, subscription billing, separate company accounts and bulk data migration require an agreed scope based on your requirements.
How do revisions work?
Basic includes 1 revision round, Standard 2 and Premium 3. Each round covers one consolidated set of adjustments within the agreed scope. New features are quoted separately. Defects found during delivery review are corrected without using a revision.
Can you maintain or expand the application later?
Ongoing maintenance, new modules and future improvements can be arranged through a separate Fiverr order. The scope, response times and cost are agreed before that work begins.
