Custom CRM systems
We build custom CRM systems when off-the-shelf platforms cannot support the required logic, roles or data model.
Web Development
Custom web applications for business
We build CRM systems from scratch, B2B portals, client dashboards, and internal tools tailored to your processes. For teams that have outgrown off-the-shelf software or find customising it more expensive than building it right.

Fit
When this is the right choice
Custom development makes sense when your process doesn't fit inside any standard product.
- Your workflows don't map to any standard SaaS — every option needs workarounds
- Your current system is a bottleneck and the team works around it instead of with it
- You need an internal tool: a dashboard, client portal, or partner workspace
- You've tried off-the-shelf and hit the ceiling on customisation or pricing
- You need deep integration with your ERP, CRM, or other internal systems
What we build
We build application-layer products around real business processes, not CMS templates.
B2B portals
Client portals for wholesale buyers and partners: orders, documents, pricing, and self-service flows.
Role-based portals
Interfaces with authentication, access control, approvals, and custom flows for different user types.
Project and document management
Systems for tasks, projects, contracts, approvals, and operations — no handoff gaps between departments.
Internal tools and analytics
Dashboards, reporting, and automation for teams that have outgrown spreadsheets and manual processes.
Corporate portals
Internal services for employees, partners, and branches with unified access to company data and processes.
Tech stack
We choose the stack for development speed, maintainability, and predictable product evolution after launch.
Frontend: Next.js, React, TypeScript, TailwindCSS
Fast interfaces, predictable component architecture, and a solid foundation for complex portals and dashboards.
Backend: Node.js, NestJS, PostgreSQL, Prisma
Typed server layer with a reliable relational database, clear data schema, and straightforward integration support.
Infrastructure: Docker, CI/CD, monitoring
Automated deployments, reproducible environments, and basic observability from day one — not after the first incident.
Authentication and permissions
We use NextAuth, Clerk, or a custom scheme where complex access control and multi-tenant user separation is needed.
Integrations: REST API, GraphQL, webhooks, queues
This stack lets us connect your app to ERP, CRM, and third-party services without brittle workarounds.
When we're not the right fit
An important filter: some projects are objectively faster and cheaper to solve a different way.
- You need a landing page or promotional site — there are faster and cheaper ways to get that done
- You want a quick template-based website — that's a web design project, not custom development
- An off-the-shelf CRM covers 80% of your needs — in that case, implementation beats building from scratch
- You need something in two weeks with no scoping — we work with defined requirements and don't promise unrealistic timelines

Timeline
How long it takes
A standard web application takes 3 to 6 months depending on complexity. An MVP can go live in 1–2 months.
Weeks 1–2
Discovery, requirements definition, and architecture design.
Weeks 3–6
MVP development and core functionality running on a staging environment.
Weeks 7–12
Feature expansion, integrations, testing, and scenario stabilisation.
Weeks 12–14
Launch, data migration, team onboarding, and first iterations based on real usage.
