Every system in production has a name behind it.
Syntalith is an engineering team. We registered the company in October 2025, but we were building and running production systems long before that. A process scan is run by an engineer who owns the architecture, integrations, or agent. Not a salesperson.

Backend for large European companies: PLM, CRM, enterprise
Seventh year in commercial .NET. Built PLM systems for global food and consumer-goods manufacturers: high-volume data-exchange APIs, MS SQL and Oracle, asynchronous processing and high-stability production. Earlier he built an internal CRM and engineering-automation platform for 100+ users from scratch, including drawing generation through the AutoCAD .NET API. At Syntalith he owns the agent-systems backend and integrations with client systems; he is also the lead engineer behind odbierze.ai, the phone voicebot run in production.

Trusted external auditors
A second pair of eyes on complex audits.
Day to day they run production LLM systems in large organizations. We know each other from university: the same year and the same computer-science group at Lublin University of Technology. On complex audits and architecture they join a project as an independent second pair of eyes, under their own names.
Leads a GenAI team at a global consulting firm; previously lead software engineer at a major Polish enterprise software vendor. Python microservices, on-premise Kubernetes, RAG from classic implementations to multi-agent systems, hosting and fine-tuning open LLMs. He has walked the whole road in IT: from tester, through engineer and solution architect, to team lead.

Spent four years building and running a high-traffic backend at a major Polish enterprise software vendor: a RAG chat platform with vector search, asynchronous data pipelines with monitoring (Celery, RabbitMQ, Prometheus), agent integrations (LangChain, LangGraph, MCP) and automated deployment of local LLMs (vLLM) on Kubernetes with resource-aware scheduling.

Business development
Who books the calls.
The first message from Syntalith usually comes from Daria: outreach, qualification and the calendar. The technical conversation and the process scan always belong to an engineer.
Daria Sandach
Business Development
Verify profileAt Syntalith since August 2025 she runs prospecting, qualification and the calendar, also for odbierze.ai. She talks with owners about where a team loses time and context and whether an AI agent makes sense in a given process; her background is business psychology. If you are booking a scan, it is most likely with her.
Meet the engineer who will lead your build.
- 30 minutes with the engineer who would build it, not a salesperson.
- A review of the processes that cost you the most time and money.
- A written summary: what to automate, in what order, with cost ranges.
Times are shown in your own time zone. We work with clients across time zones.
No sales deck and no obligations. If automation doesn't make sense, we'll write that too.
No build work before a signed proposal.
