Custom Development
Bespoke software solutions built with modern technologies including Next.js, React, and Node.js, designed for scalability and long-term maintainability.
Software Built for Your Business
Custom development is the design and engineering of bespoke software — web applications, internal tools, APIs, and customer portals — built to fit business processes that off-the-shelf products cannot cover. eelik d.o.o. builds custom applications for clients in the DACH region and Southeast Europe using a TypeScript-based stack of Next.js, React, Node.js, and PostgreSQL, with automated testing, CI/CD, and monitoring included from the first iteration. Full source code and intellectual property are transferred to the client on delivery.
Our Technology Stack
We develop with a modern, proven stack centered on TypeScript across the full application layer. On the frontend, we use React and Next.js to build fast, accessible user interfaces with server-side rendering and static generation where appropriate. On the backend, Node.js provides a performant runtime, and PostgreSQL delivers reliable, scalable data storage.
This stack is chosen deliberately — it's widely supported, well-documented, and backed by thriving open-source communities. Your application won't depend on niche frameworks that may lose support in a few years.
Our Development Process
Every project starts with a discovery phase where we understand your business requirements, user needs, and technical constraints. We then define a clear scope, architecture, and delivery plan. Development follows agile principles with regular demos, feedback cycles, and iterative refinement.
We write clean, tested, well-documented code. Every application includes automated testing, CI/CD pipelines, and monitoring from the start. We don't cut corners on the foundations that determine long-term quality.
Beyond Launch
Software is never truly finished. We offer ongoing support and maintenance agreements to keep your application secure, performant, and evolving with your business. Whether you need a web application, an internal tool, or a customer-facing platform, we deliver solutions that last.
Benefits
Frequently asked questions
What kinds of applications does eelik build?
We build web applications, internal tools, APIs, customer portals, and integrations using a modern TypeScript-first stack (Next.js, Node.js, PostgreSQL). Projects range from small targeted tools to multi-year platform builds.
How long does a typical custom project take?
An MVP for a focused internal tool usually takes 6 to 10 weeks. Larger platforms run 4 to 9 months, broken into 2 to 4 week iterations with working software at each milestone, so business value is realized incrementally.
Do you provide ongoing support after launch?
Yes. We offer flexible support agreements covering bug fixes, security updates, infrastructure operations, and incremental feature work, scaled to the criticality of the system.
Who owns the source code and intellectual property?
You do. All custom code, designs, and documentation are delivered under terms that transfer full ownership and IP to the client; we keep no usage rights beyond what the contract specifies.
