I keep business systems running and connect AI to them.

I support enterprise applications and build API integrations and automation. I also connect LLMs to these systems. I am open to conversations about AI consulting, AI-assisted development and AI-powered tools, in Tallinn or remotely.

About

I am an enterprise IT and integration specialist. I learned my skills on the job. I have 15+ years of experience with applications, automation, EDI, web development and system operations.

I work mostly with Microsoft and Azure. I also work with Linux, web servers and databases. I automate repeated tasks, monitor the systems I run, and write down each step so that other people can do it again.

I use AI when it makes a task faster or more correct. Examples: LLM services that return structured data, AI agents that use existing applications, and LLM-assisted development. I connect these to business applications, ERP systems and data platforms.

Outside my job, I work on AI consulting topics: AI-assisted development, AI-powered websites and internal tools, and LLM integration with existing applications.

AI engineering

I built and operate each of these systems myself.

Structured LLM services

Typed output with usage limits.

Details: Structured LLM services

The service returns LLM answers as typed data. Other software can use this data directly. Each caller has usage limits.

  • Typed questions that return probabilities
  • Per-key rate and daily spend limits
  • Short responses
  • Agent documentation made from the code

Safe agent access

Limited tools in existing apps.

Details: Safe agent access

AI agents work in existing web applications. They use the signed-in session of the user.

  • Tools that work only on their page
  • Dry-run checks before each write
  • Writes that are safe to repeat
  • Least privilege: the agent gets only the permissions of the page session

Production AI operations

Safe keys and known costs.

Details: Production AI operations

API keys, spend limits and cost tracking for AI features in production.

  • API keys stay on the server
  • A spend limit for each request
  • Costs recorded for each application
  • Secrets removed from output, and SSRF protection

Speech-to-text pipelines

No lost recordings.

Details: Speech-to-text pipelines

Dictation and meeting recordings become text that people can use. Audio is not lost when a step fails.

  • Audio capture in the browser and from meetings
  • Transcripts with speaker labels and keywords
  • Recordings are kept safe until processing is complete
  • Works with different speech-to-text engines

Agent-first service design

One service for people and AI agents.

Details: Agent-first service design

People use the service in a browser. AI agents use the same service through an API. Work can move between people and agents.

  • HTML, JSON and Markdown representations
  • Polling that sends only changes
  • Clear states that show who has the task: a person or an agent
  • Agents claim a task and restate it before they start
  • Coding agents started and steered from any device

Many AI tools, one workflow

Not tied to one AI tool.

Details: Many AI tools, one workflow

I use several AI coding tools and agent harnesses, each for the work it does best. Skills and instructions are shared between them.

  • Claude Code, Codex and GitHub Copilot for coding
  • Hermes and OpenClaw as agent harnesses
  • Herdr and Rex to run and supervise several agents at the same time
  • OpenRouter for access to many models through one API
  • Versioned skills that work in all of these tools
  • Credentials are not in source control

Everyday automation with AI

Small scripts that save time daily.

Details: Everyday automation with AI

Scheduled scripts collect information from different services, summarise it with AI and send short updates to the people who need them.

  • Daily digests from several sources, written for non-technical readers
  • AI summaries and translations, with checks on their quality
  • Notifications to chat and e-mail
  • Server housekeeping: updates, backups, and log and secret checks

Security operations with AI agents

Daily checks, safe handoffs.

Details: Security operations with AI agents

AI agents check servers and new vulnerabilities every day. They report findings that a person or another agent can act on.

  • Daily server scans with structured findings and fix briefs for a second agent
  • Log text that an attacker controls never reaches the prompt, and risky suggested commands are blocked
  • Vulnerability feeds filtered to the products in use, with impact checks on my own servers
  • Repeatable security audits as versioned agent skills

Document search for agents

Local search over business documents.

Details: Document search for agents

Documents stay where they are. People and AI agents can search them in one place.

  • Reads PDF, Word, Excel, PowerPoint and e-mail files, including attachments
  • Splits documents into sections and ranks results with full-text search
  • A command-line tool with stable JSON output for agents
  • Several agents can write to one index safely

Screen recordings to instructions

Numbered steps from a video.

Details: Screen recordings to instructions

A recording of a task in a business application becomes step-by-step instructions that people can review and edit.

  • Finds the important moments in the recording
  • Writes clear, numbered steps
  • People review and edit the result
  • Exports the steps as text, Markdown or a page with screenshots
