How do you estimate custom software?

We scope in discovery, estimate per feature with ranges and refine as we learn. For fixed-price work the scope is documented and changes are managed explicitly.

Will we be locked in to you?

No. Standard stacks, documentation, tests and your ownership of the repository mean any competent team can take over.

Can you integrate with our old systems?

Yes. Integration with legacy and enterprise systems is a normal part of our work, including building APIs where none exist.

When should we add SSO and audit logs?

Before your first enterprise deal, not during it. We plan enterprise readiness into the roadmap early so it does not become an emergency.

Overview

When off-the-shelf software does not fit the way your business works, custom software is the answer. We build web platforms, APIs and enterprise applications to your requirements, with an architecture your team can maintain and a codebase you will not be embarrassed to show a new hire.

Our engineering practice is deliberately conventional where it should be: modern but proven stacks, automated testing, CI/CD, documentation and security by default. Novelty goes into your product, not into the tooling.

This page also covers SaaS product engineering and native or cross-platform mobile app development.

Custom software development

When off-the-shelf software does not fit the way your business works, custom software is the answer, built with an architecture your team can maintain.

Web application development

Customer portals, internal platforms and workflow applications built with modern frameworks.

API and microservices development

Well-documented APIs and services designed for integration and scale.

System integration

Connecting new software with ERP, CRM, payment, identity and partner systems.

Security engineering

Authentication, authorization, secure coding and readiness for security review.

Typical use

Replacing spreadsheets and email with a proper operational system
Customer and partner portals connected to back-office systems
APIs that expose your data and services to partners and products

SaaS product development

SaaS looks like a product but runs like a service. Multi-tenancy, subscription billing, onboarding, security, uptime and unit economics are as much a part of the product as the features.

SaaS architecture

Multi-tenant data models, tenant isolation, scalability and cost-efficient infrastructure.

Subscription and billing

Plans, metering, trials, invoicing and integration with Stripe and other billing platforms.

Enterprise readiness

SSO, role-based access, audit logs, data residency, compliance support and SLAs.

Growth engineering

Analytics, experimentation and performance work that improves activation and retention.

Typical use

Startups building a SaaS product from validated idea to launch
Companies converting an on-premises or single-tenant product to SaaS
Established SaaS products scaling to enterprise customers

Mobile app development

A mobile app is judged in seconds and abandoned in minutes. We build native and cross-platform apps for iOS and Android with the backend and release process to keep them healthy.

Native iOS and Android

Swift and Kotlin apps where platform fidelity and performance are essential.

Cross-platform development

React Native and Flutter apps for faster delivery across both platforms from one codebase.

Backend and API development

Scalable services, authentication, push notifications and offline synchronization.

App store release and operations

Build pipelines, beta programs, store submissions, crash monitoring and updates.

Typical use

Customer apps for banking, retail, travel and healthcare
Field service and workforce apps that work offline
Companion apps for connected devices and IoT
