Each link below opens a page with deliverables, who it is for, and how we typically run the work. Not sure which fits? Book a call and we will point you in the right direction.
AI
Add smart search, chat, and automation to software you already have or are building. We set it up so it works reliably after launch, not just in a demo.
Wire OpenAI, Claude, or other models into your app with spending limits, error handling, and keys kept off the frontend.
Train your product to answer from your documents and keep answers consistent as you update content.
Support bots and internal assistants that read from your systems, hand off to humans when stuck, and run on cloud or your own servers.
Product
Customer-facing websites, admin panels, and mobile apps. Designed, built, and handed over with docs your team can maintain.
Business websites, portals, and dashboards in React or Next.js with login, payments, and admin tools where you need them.
iOS and Android apps, including cross-platform builds. We help with store submission, push alerts, and offline use.
Wireframes and Figma designs developers can build from, tested on real tasks before code starts.
Backend
The server side: databases, billing, user accounts, and APIs that your web or mobile app depends on.
Multi-customer software with signup, subscriptions, plan limits, and an admin view for your team.
Server logic, databases, and documented APIs so your frontend or partners can integrate without guesswork.
Team & ops
Extra engineers on your team, safer releases, and security basics built in from the start.
Senior engineers who join your Slack, standups, and repo. Full-time or part-time, matched to your stack.
Automated deploys, staging environments, and tests on the flows that matter so releases stop breaking production.
Login with company accounts, encrypted data, GDPR-friendly workflows, and prep for enterprise security reviews.
