Contact center · Voice AI · CRM integration
I’m Petr Bartek, an independent engineer with 15+ years in contact center software. I implement and extend Sprinklr and Genesys, build voice AI and conversational agents, and integrate the CRM and backend systems around them — Dynamics 365, Salesforce, C#/.NET and Java.

Services
I take a project from the first workshop through design, implementation and handover. I write the code myself and stay with the solution until it runs in production.
Implementation, extension and integration of Sprinklr Service and Genesys: routing and queues, guided workflows, agent desktops, custom entities and the reporting around them.
Custom ElevenLabs voices, conversational AI agents and LLM integrations — designed with clear guardrails and a defined hand-over to a human agent.
Dynamics 365 and Dataverse development, Salesforce integration and data migration, and custom internal systems — from order management with AI document extraction to operational dashboards.
Experience
A condensed, factual timeline. Client names stay confidential; I list the industry and region instead.
Sprinklr Service implementations for clients in banking, telecommunications, fibre, retail and automotive across Central and Western Europe: voice, chat, email and social channels, Salesforce integration and data migration, AI quality management and operational tools built on the Sprinklr API.
C# plugins, workflows, SSRS reports and an Azure Function for e-invoicing in the sales and licensing CRM of a German engineering-software vendor.
Order-management system for a Czech CNC machining company, with go-live planned: customer orders, subcontractor purchase orders and partial invoicing, AI extraction of PDF orders with human approval, an append-only audit trail and integration with the Pohoda accounting system. TypeScript, React, Node.js, PostgreSQL, Google Cloud, Claude API.
Genesys Cloud module integration and React agent desktop extensions, custom ElevenLabs voices, and Apigee API proxies between DialogFlow CX bots and Java backend services.
