Our Services

Agentic Engineering

AI agent systems, tool-use architectures, LLM integrations, and autonomous workflows that solve real problems without babysitting.

Full-Stack Development

Shopify Development

Custom Shopify themes, app integrations, and store optimization. Performance audits, migration help, and fixing what the last agency left behind.

Technical Consulting

Architecture reviews, technology strategy, and hands-on guidance for teams building software. No slide decks, just answers.

DevOps & Infrastructure

CI/CD pipelines, cloud architecture, containerization, and deployment automation. Reliable infrastructure so your code actually ships.

API Design & Integration

Third-party API integrations, webhook systems, and API-first architecture. Clean contracts, proper error handling, and documentation that doesn't lie.
