I will build a custom admin panel CRM or internal web application
Kordian Z
About this gig
Need software built around the way your business actually works instead of another generic tool filled with features you never use?
I build custom web applications, admin panels, internal tools, CRM-style systems and SaaS functionality across frontend, backend and database layers.
Possible features include:
- customer and company management
- projects, orders and workflows
- tasks and statuses
- dashboards
- user roles and permissions
- search, filtering and reporting
- documents and attachments
- REST APIs
- PostgreSQL databases
- third-party integrations
- realtime functionality
- responsive interfaces
I work across React/TypeScript applications, Node.js backends, APIs and PostgreSQL, but I do not prescribe a technology stack before understanding the project.
Architecture and technology should follow the requirements, expected scale, integrations, hosting constraints and future plans not a random framework choice.
Please contact me before ordering a larger system. I will help define the scope and split the project into sensible deliverable stages.

I’m a Software Engineer with professional experience building and maintaining web applications, backend services, APIs, databases, and internal business systems.
My commercial background includes TypeScript, React, Node.js, NestJS, Fastify, Django, PostgreSQL, WebSockets, Docker, CI/CD, and modern frontend architecture.
I work across the stack: from responsive user interfaces and complex application state to backend architecture, API design, database modeling, integrations, deployment pipelines, debugging, and performance improvements.

FAQ
Can you build my entire CRM or SaaS product?
Yes, but larger systems should be scoped before ordering. We can divide development into milestones and deliver the product incrementally.
Why don't you specify one fixed technology stack?
Because the right architecture depends on the requirements, integrations, expected scale, deployment environment and future development plans. I have preferred tools, but I do not force them onto every project.
Can you recreate an existing business process as software?
Yes. Understanding the workflow, roles, data and exceptions is an important part of designing custom business software.
Can you build user roles and permissions?
Yes. Please describe the required roles and what each user should be allowed to access or change.
Can you integrate email, payments, invoicing or calendars?
Potentially yes. The exact scope depends on the external service and its API.
Is UI/UX design included?
I can design clean functional product interfaces as part of application development. If you need a complete branding exercise or highly specialized visual design, that should be scoped separately.
Does the Premium package include unlimited features?
No. Premium is a scoped MVP foundation. Large CRM/ERP/SaaS applications are multi-stage projects and require a custom scope.
Can you maintain the system afterwards?
Yes. Continued development and maintenance can be arranged after the initial delivery.
