AI agents —
from demo to production.

I'm Samuli Vainio — I design and build AI agent solutions that go beyond the demo: into production, real use and long-term operations. Built on over 20 years of full-stack and cloud engineering.

Who

I build AI agents with the same discipline as critical production systems — from architecture and security to CI/CD pipelines and operations.

I focus on LLM-based agents and automation that do real work in production: they connect to existing systems and data sources, their behavior is measurable and monitored, and their boundaries are deliberate. Production-readiness doesn't come from the language model — it comes from everything built around it: architecture, integrations, testing, and deployment.

The foundation is over 20 years of hands-on experience building and operating web-based digital services across many industries. Since 2019 I've worked on a large public-sector digital service — a nationwide, citizen-facing e-service in Finland — first as a full-stack developer and now as DevOps Lead. That's where the things that decide whether an agent makes it to production come from: integrations, security, CI/CD, and owning what runs in production.

My own products put the same approach into practice: AI agents and ML services running in production — an AI assistant that writes publish-ready marketplace listings, and bots that analyze financial-market and sports data and deliver the results over Telegram. Serverless on AWS or as containerized services.

Across all commercial engagements, I use either Anthropic or OpenAI models to support planning, implementation, testing, and review. I agree the handling of client materials in advance, verify the outputs myself, and remain accountable for the result.

I deliver commercial engagements through my company Poggers Oy. Up-to-date services, boundaries, and prices are available at poggers.fi.
