Custom engineering, scoped around the result you need

Build or integrate VoIP and SIP systems

Connect your CRM, store or internal tools to Asterisk-based PBXs, or build call handling that fits how your team actually works.

What you get

• Click-to-call, screen-pop and call logging for your own software
• Asterisk AMI/ARI integrations and dialplan work
• Call analytics, missed-call workflows and notifications

Build CRM and call-center solutions

A CRM shaped around how you sell, a call center wired into it, or both — built on the same engineering as Darwvin CRM and Darwvin Call Center.

What you get

• Custom CRM modules, pipelines and reporting
• Queues, IVR, recordings and supervisor dashboards on Asterisk
• Calls, customers and orders connected in one place

Build full-stack web applications

Customer-facing sites and business applications, from the database to the interface, built to be fast, accessible and maintainable.

What you get

• Next.js and React front ends that score well on Core Web Vitals and accessibility
• APIs, authentication, roles and an admin panel
• Automated tests and a deployment you can operate

Build Android applications

Native Android apps for your customers or your field teams, including apps that talk to your telephony or back office.

What you get

• Native Kotlin apps with offline-tolerant data
• API integration, authentication and push notifications
• Play Store release, or private distribution for internal apps

Build a SaaS product

Take a product from specification to a deployed, billable service: accounts, roles, billing hooks, admin tooling and monitoring.

What you get

• Product architecture and a milestone plan you can budget against
• Web app, API and admin panel
• Deployment, backups and monitoring on your infrastructure

Build backend and API infrastructure

APIs, background jobs and data models that stay correct under retries, restarts and concurrent requests.

What you get

• REST APIs in TypeScript, Go or PHP
• PostgreSQL schemas, migrations and query tuning
• Queues, outbox patterns and idempotent webhooks

Fix or rescue a struggling application

For software that is slow, unstable or stuck: we find what is actually broken, stabilise it, and leave it maintainable.

What you get

• Code and infrastructure audit with a prioritised fix list
• Security and data-integrity fixes first, then performance
• Tests and CI around the parts that kept breaking

Automate business workflows

Replace manual copy-paste between systems with jobs that run on schedule, retry safely and report when something needs a person.

What you get

• Scheduled jobs and event-driven workflows
• Data sync between CRM, store, accounting and messaging tools
• Alerts and audit logs for every automated action

Build integrations and commercial plugins

WordPress, WooCommerce and Perfex CRM extensions built to be sold: licensing, updates, setup wizards and diagnostics included.

What you get

• Plugins and modules with license checks and update channels
• Third-party API integrations
• Source protection for code you distribute

Develop custom internal tools

Admin panels, dashboards and operator tools that fit your data and processes instead of a generic template.

What you get

• Admin panels over your existing database
• Operational dashboards and reports
• Desktop tools where a browser isn't enough
