Custom software development
4 – 12 weeks · 2 – 4 senior engineers. Most of our work replaces a mix of spreadsheets, inboxes and SaaS tools that no longer fit how the company operates.
Services
Custom software development services
One company for the whole software lifecycle: custom software and CRM development, web and mobile apps, business automation and AI integration, websites and landing pages — for businesses in any industry. Discovery, design, development and long-term support by a senior team; fixed scope in writing, and the code, accounts and data belong to you.
Services
What we build
Every service page lists scope, timeline, related work and answers to common questions.
Custom CRM development
6 – 10 weeks · QuickBooks, RingCentral, Gmail. Only the parts your process needs — nothing you will never use.
Custom database development
4 – 10 weeks · PostgreSQL, Node.js, React. A database is only useful with the application around it. We deliver both.
Business automation
1 – 4 weeks · QuickBooks, CRM, phone, email. Repetitive work between systems — the kind that eats hours every week and causes mistakes.
AI integration & automation
2 – 6 weeks · OpenAI, Anthropic, open models. Focused features with a measurable job to do — not a chatbot for the sake of having one.
Web app development
6 – 12 weeks · TypeScript, React, Node.js. The parts that make a web product usable by paying customers — built in from the start.
Mobile app development
6 – 12 weeks · iOS & Android. Apps that are part of a working system — not a standalone screen set.
Website development
1 – 4 weeks · Design, CMS, forms, SEO. Everything a small or mid-size company needs to be found and contacted — and nothing that slows the site down.
Landing page development
~1 week · Copy, design, tracking. Built for one campaign or one offer — and measured from the first visit.
