Kristjan Suursoho

Engineer by trade, artist by mistake.

I'm Kristjan, a full-stack engineer working independently through lebo.agency.

For close to a decade, much of my work has focused on digital accounting workflows across business expenses and sales invoicing.

At CostPocket, I helped build software that collects and digitises receipts and purchase invoices into structured accounting data. My involvement began in 2018 and continued through the company's acquisition by Mynt in 2026.

Through Outvoicer, I have worked on the other side of that flow, building services that generate and deliver sales invoices as PDFs and structured UBL and PEPPOL e-invoices.

Beyond financial systems, my experience extends into IoT, LLM applications, agentic workflows, MCP integrations, retrieval systems, and conversational interfaces.

Where I am going

I am now looking to take the next step with a company that accepts AI in both its products and development process. I want to bring the full breadth of my experience in financial systems, IoT, product engineering, and AI to a team building ambitious and useful technology.
