AI Architect & CTO

Transforming operational complexity into competitive advantage

Co-founder at Jaden Data — building enterprise AI on AWS (and available for consulting)

Jacek Janczura

I'm the Co-founder & CTO of Jaden Data. We build process intelligence—AI-native systems that improve how work gets done in real enterprise operations. We don’t start with “AI features”; we 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, and enterprise operations—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.

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.
