Custom AI & Agentic Systems built for live production.
We bridge the gap between proof-of-concept AI demos and hardened production software. We build deterministic enterprise agentic systems: low-latency streaming inference (<250ms), hybrid dense/sparse RAG pipelines, PII masking, and autonomous tool-calling agents securely integrated with your private databases.
Architecture & Code Standards
Most AI prototypes fail in production because LLMs are non-deterministic, prone to hallucinations, and expensive to run. Steigern Tech builds production-grade agentic architectures. We implement defensive guardrails, structured JSON schema outputs, semantic caching, and tool-calling validation that ensure outputs are accurate, predictable, and compliant.
We treat models as dynamic reasoning engines, not magic black boxes. We combine vector embeddings with keyword search (Hybrid RAG) for pinpoint factual retrieval; we implement token budget management to prevent runaway API billing; and we build self-healing agent pipelines that detect and correct format errors before results reach the user.
Hybrid Dense & Sparse RAG
Vector embeddings combined with BM25 keyword matching and cross-encoder reranking over internal knowledge bases.
Zero-Retention PII Masking
In-memory pseudonymization masking names, phone numbers, and financial data before model ingestion.
Self-Correction Agentic Loops
Autonomous tool-calling agents that execute database queries, inspect output schemas, and self-correct invalid parameters.
Production Capabilities
Granular technical deliverables engineered for high reliability, maintainability, and scale.
Autonomous Tool-Calling Agent Pipelines
Multi-step reasoning agents that execute SQL queries, trigger webhooks, and interface with private business software.
Hybrid Retrieval-Augmented Generation (RAG)
Pinecone and pgvector indexing with cross-encoder re-ranking, source attribution citations, and semantic cache layers.
Enterprise PII Sanitization & Data Guardrails
In-memory token masking ensuring sensitive customer data, SSNs, and credit cards are never transmitted to third-party model APIs.
Automated OCR & Unstructured Document Intake
Vision LLM pipelines that extract tabular data, line-item invoices, and legal contracts directly into relational databases.
Local & Private LLM Deployment (vLLM / Ollama)
Self-hosted open-source models (Llama 3, Mistral, Qwen) on private AWS/GCP GPU instances for total sovereignty.
Streaming UI & Natural Language Chat Interfaces
Silky smooth React/Next.js streaming text responses with syntax highlighting, citation footnotes, and export actions.
How We Turn Demos into Production Software
Moving from an impressive prompt to an enterprise-grade AI system requires serious systems engineering.
Semantic caching using Redis to return instant answers for duplicate questions and slash API tokens by 60%.
Deterministic JSON schemas that fail closed if the model deviates from the required output contract.
Comprehensive telemetry logging latency, token consumption, and confidence scores across every inference.

A partner who's already shipped in your category.
Depth compounds. Our custom ai & agentic systems practice has shipped production software for high-scale enterprise clients — your architecture is a recognisable pattern, not an experiment. See live portfolio work across industries.
10+ years, 200+ projects
Since 2014, we've shipped custom ai & agentic systems solutions across Europe, the US, and Asia — your category is a known quantity, not a discovery engagement.
AI embedded, not bolted on
Intelligent features are designed into the architecture from sprint zero — not added as afterthoughts when roadmap pressures mount.
Global delivery, one team
Follow-the-sun delivery across US, UK, and Asia-Pacific overlap means your engineering roadmap never waits for a timezone to wake up.
Code you own on Day 1
Direct Git commits pushed directly into your private repository from the first sprint. Clean documentation, zero IP lock-in, and 100% intellectual property ownership.
Production standards by default
Strict automated CI/CD quality gates, ISO 27001 data practices, deterministic regression test suites, and zero unvetted dependencies in production.
Enterprise scale guaranteed
Architectures engineered to handle concurrency spikes, multi-tenant databases, and seamless horizontal cloud auto-scaling with sub-second response times.
Questions before we scope your Custom AI & Agentic Systems.
Answers to technical architecture, IP ownership, sprint timelines, and handover standards.
Idea to Market–Ready Product
We turn your idea into a secure, compliant, and test-ready product in weeks, not months.
Inquiry & Scoping
We rapidly decompose requirements, pressure-test commercial viability, and align technical scope before capital is committed.
