001// Own your automation

Built in-house,
owned by you.

We deliver in-house builds where you fully own the source code and IP. No lock-ins, no black boxes. Four pillars, one partner — end-to-end engineering on your terms, scaling and adapting as you grow.

Every system we ship is yours to keep, extend, and run independently.

The result is leverage: high-impact engineering without the vendor leash.

002// What we build

Four pillars.
One partner.

End-to-end engineering on your terms — automation, blockchain, robotics and security, built in-house and handed over with the source.

Pillar 01

Intelligent Automation

Remove manual work. Ship reliable ops.

  • Finance: invoicing, bank rec, payroll, VAT
  • Sales & CRM, proposals, outreach
  • RAG assistants over your docs & data
  • Compliance monitoring & reporting
Pillar 02

Blockchain — Solana & Ethereum

High-performance programs you control.

  • Solana (Anchor), SPL tokens, escrow, marketplaces
  • Ethereum (Foundry/Hardhat), ERC-20/721/1155
  • Oracles, multisig, auctions, vesting
  • Audits, dashboards, on-chain monitoring
Pillar 03

Electrical Automation & Robotics

From sensors to robotic cells.

  • PLC/SCADA (Siemens, Allen-Bradley, Beckhoff)
  • Motion, safety circuits, machine vision
  • Sensor fusion, data logging
  • IIoT dashboards & alerts
Pillar 04

Cybersecurity Consulting & Mitigation

Defend IT, OT, and on-chain systems.

  • Risk assessments, hardening, IAM
  • Pentesting, incident response, forensics
  • Smart-contract & LLM red-teaming
  • NIST/ISO-aligned roadmaps
003// AI & Retrieval
Retrieval-augmented · Agentic · Self-hosted Private by default

AI that reasons over your data — and never leaves your infrastructure.

We don't bolt a chatbot onto your business. We build grounded retrieval systems and autonomous agents that run on open-weight models you host yourself — so answers stay accurate, auditable, and entirely under your control.

Retrieval (RAG)
Grounded answers with citations, no hallucinated guesswork.
  • Hybrid semantic + keyword search
  • Cross-encoder reranking
  • GraphRAG over knowledge graphs
  • pgvector / Qdrant vector stores
  • Source citations & guardrails
Reasoning & Agents
Models that plan, act, and verify across multiple steps.
  • Tool-calling & function execution
  • Multi-agent orchestration
  • Multi-hop & self-correcting loops
  • Structured output & validation
  • Human-in-the-loop checkpoints
Deployment & Ops
Your models, your servers, your data boundary.
  • Self-hosted Llama 3 / Mistral via vLLM
  • Fine-tuning & LoRA adapters
  • Eval pipelines (RAGAS) & tracing
  • Prompt caching & cost control
  • On-prem / VPC, zero data egress

A1

Autonomous Agents

Workers, not one-shot prompts.
  • Plan, call tools, and finish multi-step tasks
  • Reason across systems autonomously
  • Recover and retry on failure
  • Report results back into your stack
A2

Outbound Engines

Personalised outreach at volume.
  • Research, enrich, and draft per-lead
  • Scale send without adding headcount
  • Trigger on real-time signals & intent
  • Sync straight into CRM pipelines
A3

Generative UI

Interfaces that shape themselves.
  • Layouts assembled around user intent
  • Adapt in real time as context shifts
  • Generative components, not fixed screens
  • Streaming, responsive interactions
A4

Workflow Architecture

Logic made machine-executable.
  • Map and model your operational logic
  • Rebuild it as readable, runnable pipelines
  • Branching, approvals, and audit trails
  • Observable, versioned, and owned by you
//Stack

The stack.

Open-weight models, battle-tested chains and industrial control — the tools we build and hand over with.
