GovTech
C-Portal is a digital service portal that lets residents order municipal services online anytime, from any device.
The platform centralises key city services — from waste and bulky-item collection to container requests, schedule changes, and appointments.
C-Portal runs on a modern React/Next.js front end, Node.js services, and Docker, keeping it secure and easy to expand with new municipalities.

Bringing public services online meant building a shopping-simple portal that safely handles complex municipal systems.
87%
of service requests now come through C-Portal instead of phone or email, greatly reducing manual work for city staff.
98%
reduction in average response time for waste and service orders thanks to smart digital forms and automated routing.
95%
of surveyed residents, most rate C-Portal as ‘easy’ or ‘very easy’ to use, boosting overall satisfaction with local public services.
Challenge
Digitalising fragmented city service requests
Before C-Portal, residents used phone, email, or separate sites for city services. Requests were incomplete, hard to track, and time-consuming. The city needed a single, citizen-friendly portal.
Solution
Unified citizen portal with deep system integration
We built a single portal where residents submit requests and see time slots. Node.js services manage logistics, scheduling, and accounting, ensuring each order is tracked, priced, routed.
Bulky waste

Outcome
C-Portal delivered a fully digital, transparent way for residents to interact with municipal services.
Instead of through multiple phone calls and emails, requests now flow through a single online entry point with consistent forms, status updates and notifications. City operators handle structured data, which speeds up processing and reduces errors.
C-Portal lets residents and the municipality handle waste and schedules through a quick, predictable online experience that saves time and builds trust.

FAQ
Got Questions?
Our approach is to design an MVP that can go live quickly, but on top of an architecture that is ready to scale. The same team can then continue with you to add features, improve performance and support growth.
Yes. We often step into running products to stabilise architecture, redesign UX, improve performance or add new modules—without stopping your current business operations.
We begin with a short discovery phase: clarifying goals, success metrics, scope and constraints. Based on this, we propose a roadmap, team composition and timeline so everyone is aligned before development starts.
We agree on a clear communication channel (Slack, Teams or similar) and run regular check-ins. You receive progress updates, demos and short written summaries so stakeholders always know what has been done and what comes next.
Just reach out with a short description of your idea or product. We’ll schedule a call, estimate the scope and suggest a collaboration model that fits your timeline and budget.
That’s fine. We can help you shape the product through workshops, discovery sprints and UX prototypes, then translate that into a clear backlog and technical plan for the development team.
On the front end we mostly use React, Next.js and React Native; on the back end—Node.js and microservice architectures deployed with Docker and cloud providers like AWS. For specific cases we also work with Web3 stacks and AI integrations.
We focus on end-to-end digital products: mobile apps, web platforms, SaaS tools and Web3 solutions. Our team covers UI/UX design, front-end, back-end and long-term product evolution.
