Built on solid ground. From the first useful release to the systems behind it. We design and develop websites, applications and digital products around the people who use them. ## Fit For founders validating a product, businesses replacing spreadsheets, and teams extending an existing platform. ## Scope - **Websites & web applications:** Responsive websites, customer portals and internal tools with clear journeys, accessible interfaces and purposeful content. - **SaaS & enterprise platforms:** Product foundations, role-based workflows, administration and integrations shaped around your operating model. - **Mobile & desktop applications:** Applications designed for the devices, connectivity and environments your users actually work in. - **APIs & product design:** Interface design, reusable components and documented APIs that connect the experience to reliable business logic. ## Process 1. **Define the useful release:** Agree on users, journeys, constraints and what success means before choosing implementation details. 2. **Design, build, review:** Work through prototypes and working increments, using feedback to resolve decisions early. 3. **Launch with a handover:** Verify the agreed flows, prepare deployment and document operations and next steps. ## Examples ### A new SaaS product - Challenge: You have a defined customer problem and need a first release that tests the idea. - Approach: Map the core journey, prototype the experience, then build the smallest useful product with clear roles and data boundaries. - Deliverable: A scoped application, deployment setup and a documented next-release backlog. ### An internal platform - Challenge: Your team moves the same information between spreadsheets, email and disconnected tools. - Approach: Turn the operating process into shared records, approval flows and a focused interface for each role. - Deliverable: An internal web application with agreed workflows, permissions and data import paths. ### An existing application - Challenge: A working product needs new features without disrupting the people who rely on it. - Approach: Review the code and dependencies, map the affected journeys, and release changes in manageable increments. - Deliverable: Targeted features, regression coverage and handover notes for your team. ## FAQ ### Can you work with our existing codebase? Yes. The starting point is a review of the application, dependencies, deployment and priority problems. That review determines whether targeted changes or a larger rework make sense. ### Which technologies do you work with? Jainil’s experience includes Next.js, React, Node.js, TypeScript, Docker and Linux. The stack for a project should follow its requirements, existing systems and maintenance needs. ### What happens after launch? Maintenance, technical support and further development can be included in the scope. Support coverage and responsibilities need to be agreed for the individual project. ## Reference architecture A reference web application structure. The interfaces, business rules and records have different responsibilities; the project scope determines which pieces are needed. ### Experience Customer journeys → Team workspace The screens people use to complete a task, on the devices and connections available to them. Review: Review navigation, loading and error states, keyboard access and the smallest supported screen. ### Application Business rules → Permissions & APIs The application checks identity, validates requests and applies the rules behind each workflow. Review: Check role boundaries, duplicate submissions, validation and integration failure paths. ### Operations Records & integrations → Deployment & monitoring The persistent records and runtime services that keep the application usable after launch. Review: Agree data ownership, backups, deployment access, rollback and support responsibilities. Illustrative planning model; scope and deliverables are agreed per project. [Software project planning checklist](https://juhenza.com/resources/software-project-planning) ## Technology choices Interfaces, application logic and operations ### Interface React · Next.js · TypeScript Choose rendering and interaction patterns around the user journeys, accessibility and public-page discovery requirements. ### Application Node.js · TypeScript · APIs Define validation, permissions and business rules before connecting the interface to persistent records. ### Delivery Docker · Linux Agree deployment, configuration, backups and maintenance responsibilities alongside the application. ## Quality checks before handover ### Usable journeys Check the complete task on phone and desktop, with keyboard navigation, empty records and recoverable errors. ### Reliable changes Agree automated checks for important business rules and regression coverage for the workflows affected by each release. ### A usable handover Verify setup instructions, account ownership, deployment and restoration steps with the people who will operate the system. ## Preparing for a project Bring the main user journey, examples of your current process, must-have features and any existing code or design constraints.
