Everything you need to ship AI products

From first idea to self-hosted production — one senior engineer, end to end.

AI Chatbots & Conversational AI

Multichannel assistants that answer, qualify, and convert — on your website, WhatsApp, Instagram, and Messenger.

  • Knowledge-base (RAG) answers grounded in your content
  • Button-based, lead-gen, AI, and live-chat flows
  • Integrations with your CRM, catalog, and tools
  • One assistant across web, WhatsApp, Instagram & Messenger

AI Infrastructure & Orchestration

Own your AI stack — route models by cost, run locally, and keep it observable.

  • Model routing & cost optimization (LiteLLM-style gateway)
  • Local and hybrid LLM inference
  • Multi-agent & MCP pipelines, vector databases
  • LLM observability, TTS/STT

RAG & AI Integration

Bring AI to your own data and embed it where the work actually happens.

  • Retrieval-augmented generation over your knowledge base
  • AI features inside your existing software & workflows
  • Evaluation, guardrails, and sensible fallbacks

Web, Web App & Mobile Development

Fast, accessible products — from marketing sites to web and mobile apps.

  • Marketing sites & landing pages
  • Web applications
  • Mobile apps
  • Modern, performant, accessible builds

Cloud, DevOps & Self-Hosting

Ship and run it reliably — deploy, secure, back up, and scale.

  • Docker deployments & cloud setup
  • Object storage (MinIO / S3), backups, databases
  • IAM & auth (Zitadel, OAuth, RBAC)
  • Zero-trust networking (Cloudflare, Tailscale)

Automation & Digital Transformation

Audit first, then automate — boost productivity and customer-facing workflows.

  • Digital transformation strategy & audit
  • Customer-support & lead-generation automation
  • Productivity & internal workflow automation

How I work

A simple, proven process

1

Discover

We dig into your goals, data and constraints to find the highest-leverage opportunities.

2

Prototype

A working proof of concept in days — so we validate value before scaling.

3

Build

I engineer the production system with quality, security and scale baked in.

4

Ship & run

Deploy, monitor and iterate — self-hosted and cost-optimized.
