Our own tech stack · reference architecture

A working local LLM setup with document retrieval. Everything on your own hardware – without a single token leaving your network to a US cloud.

    All data stays on your hardware. No US-cloud traffic, no third-party logs, no vendor lock-in.

    Client files, contracts, SOPs are indexed. Answers cite the original source documents.
  • Your own model, your own tools
    Llama 3.1, Mistral, or custom finetunes. Tool use via MCP for email, calendar, internal APIs.
  • Open source, full control
    Ollama + PostgreSQL + pgvector. Documented stack, no black-box plugin, no monthly API fees.

What we solve

Typical challenges in target industries

Concrete problems we can address with our technical expertise – tailored to the needs of data-sensitive industries and mid-sized businesses.

Law firm
Problem

Client information must never leave the firm – cloud AI is a non-starter.

Solution

Local LLM on your own server with RAG over client documents.

Medical practice
Problem

Appointment booking outside office hours without handing patient data to third parties.

Solution

Self-hosted booking system with your own database and GDPR-compliant hosting.

Tax advisor
Problem

Clients send receipts by email – insecure, unsorted, time-consuming.

Solution

Encrypted upload portal with automatic filing and client notifications.

Trades
Problem

No website or outdated business card – enquiries are lost.

Solution

Lean website with an enquiry workflow routed straight to the owner's phone.

E-commerce
Problem

The Shopify standard isn't enough – you need a specific feature or distinct branding.

Solution

Custom Shopify theme or your own Shopify app for the specific use case.

General
Problem

Recurring manual workflows eat hours every week.

Solution

Process automation with scripts, APIs, and purpose-built tools.

All scenarios are based on our technical expertise. If you have a specific interest, we'll put together an individual concept for you.

Who we are

Background

Sanly Tech was born from the desire to use technology pragmatically – not for its own sake, but because it solves real problems.

The founder studies computer science in Aachen and brings practical experience in web development, the Shopify ecosystem (theme and app development to OS 2.0 standards), mobile app development, game development, and cybersecurity. What's missing gets built. What's tedious gets automated.

Data privacy and security are not add-on services – they are the starting point. Especially for industries like law firms, medical practices, and tax advisors, where confidentiality is not optional but mandatory.

Future

The Vision

Sanly Tech is the beginning of something bigger.

The long-term goal is to build multiple divisions under the Sanly Technologies umbrella – from IT services to cloud infrastructure to proprietary products.

The principle stays the same: technology that works, is secure, and stays with you.
