Profile
I build and operate software products, from the initial problem and architecture to launch,
paying users and everyday operation. I have 5+ years of development experience. As the
founder of SeaLagom, I take ownership of the product, code, infrastructure and customer
experience.
I choose the language, model and development method for the task. My approach combines
one accountable developer, hands-on engineering experience and a multi-level system of AI
assistants and agents.

Multi Level AI Systems
Build hierarchies in which assistants have their own assistants, agents and subagents,
with several levels of delegation.
Direct agent workflows through voice messages in Telegram.
Use hundreds of specialized agents for development, information work, content
preparation and personal and family organization, including cooking and styling.
Create portable ecosystems of agents, including ecosystems stored on USB drives.
At my volume of work, even a $200 Claude subscription already feels insufficient.

SeaLagom
Founder and Independent Developer 2023–present
Built and operate an international maritime information platform: navigational and coastal
warnings, search, archives, maps, exports and APIs.
Own the backend, frontend, data collection and processing, infrastructure, Stripe
subscriptions, deployment and user support.
Develop the ecosystem of web and mobile software, maritime calculators, embeddable
tools and interactive learning features.

Over €700 monthly profit after operating expenses

Working Together
Looking for serious products with real users, a clear purpose and ownership of the outcome.
Fully remote work, freedom in technical decisions and clear priorities.
Project discussions and terms can be handled in chat or through agents. No video
calls, video interviews or live coding. Assess my experience through working products
and written technical discussion.
Not considering new gambling, adult-content or cryptocurrency projects, micromanagement
or extended test-task cycles. Compensation and financial terms are discussed during
negotiations.
