AI Architect & CTO
Transforming operational complexity into competitive advantage
Co-founder at Jaden Data - building enterprise AI on AWS (and available for consulting)
I'm Jacek, the Co-founder & CTO of Jaden Data. I build process intelligence-AI-native systems that improve how work gets done in real business operations of your company. I start with your workflow and make it faster, safer, and measurable.
My core strengths are AI/ML and cloud architecture: enterprise LLM platforms, RAG systems, and event-driven microservices on AWS (Lambda, ECS/Fargate, SNS/SQS). I integrate multi-model stacks (OpenAI, Azure OpenAI, Bedrock, Mistral) and deliver for regulated environments (ISO 27001, SOC 2). If you need help shipping, I also take on architecture reviews, prompt engineering + evals, and technical leadership.
Where Process Intelligence Meets Technical Excellence
Enterprise AI Platforms
Multi-tenant systems serving 50+ organizations with >1,000 concurrent connections and thousands of requests per second-built for mission-critical operations.
AWS Architecture (Serverless + Microservices)
Event-driven systems on AWS (Lambda, ECS/Fargate, SNS/SQS) designed for high throughput, reliability, and cost control.
Industry-Specific Solutions
Delivered impact across manufacturing, pharma, finance, startups, and growing companies-always tied to a measurable business outcome.
Security & Compliance
Security isn’t an afterthought-it's part of the design. Delivered ISO 27001 and SOC 2 for enterprise platforms under tight timelines.
LLMs, RAG, and Evaluations
Multi-model LLM stacks + RAG pipelines, plus repeatable evaluation approaches (tests, metrics, regression) to keep behavior stable over time.
Senior Technical Leadership
Scaled an engineering team from 0→10, led delivery end-to-end, and translate business needs into architecture and execution plans teams can ship.
Certified skydiver and diver; wind/kitesurf instructor; snowboarder. These experiences build risk management, clear instruction, calm under pressure, and disciplined preparation-skills that translate directly to technical leadership and building systems that businesses depend on.

Who is Jacek Janczura?
Jacek Janczura is an AI Architect, Co-founder of Jaden Data GmbH, and CTO, building AI-native systems for process intelligence and enterprise operations.
What is “process intelligence”?
Process intelligence means starting from how work actually gets done and then enhancing workflows with AI, automation, and data-driven decisioning-so AI serves the process (not the other way around).
What do you build?
Enterprise LLM platforms, RAG systems, and event-driven cloud architectures-often as multi-tenant SaaS products and process automation systems integrated into real operations.
What scale have you operated at?
Built platforms serving 50+ organizations, handling >1,000 concurrent connections and thousands of requests per second with high-throughput, event-driven microservices on AWS.
Which industries have you delivered for?
Manufacturing, pharmaceutical, financial services and banking, venture capital, real estate, insurance, legal, automotive, e-commerce, telecommunications, energy/cleantech, logistics, and supply chain.
What is your experience with LLMs and RAG?
Designed and shipped enterprise LLM stacks across OpenAI/Azure/Bedrock/Mistral and pioneered RAG services with automated vector database creation using Pinecone, pgvector, and Milvus, including evaluation/test frameworks for AI pipelines.
Do you work with security and compliance?
Yes. Delivered ISO 27001 and SOC 2 in ~3 months for enterprise platforms. Multi-tenant security and RBAC are core architectural concerns in my work.
How can we work together?
I take on freelance work such as architecture reviews (AWS/cloud, LLM/RAG, security, scalability/cost), prompt engineering and evals, hands-on AI delivery, and interim technical leadership / team support.
