Martin Velinský

Frontend veteran agentic software builder independent researcher

Tools for software, AI, and the stranger edges of reality.

Started with

PHP, HTML, early web

The old route: server templates, hand-built interfaces, and learning by shipping.

Moved early into

full-time JavaScript

Around 2012, before frontend JavaScript became the default center of gravity.

Current gravity

agentic software

Coding assistants, harnesses, AI delivery loops, and tools that change how teams ship.

Selected work

Four ways of refusing the default box.

These are deliberately not the same kind of project. That is the point: production software, agentic workflows, AI mechanics, physics education, and a theory of choice.

PQSE / free will

The Shape of Choice

01

A serious, speculative model of free will where consciousness is not reduced to randomness, but biases probabilities among physically available quantum outcomes.

  • +Born-rule modification through bounded probability selection
  • +Physics, philosophy, consciousness, and agency in one argument
  • +Multiple reading modes: sane, serious, angry, playground

agentic delivery

VibEnv

02

A browser-native AI change environment for teams who should not need five days, ten people, and a ceremony chain to fix a thirty-second UI problem.

  • +Runs in the customer environment instead of replacing their workflow
  • +Turns assisted edits into pull requests for normal code review
  • +Built around enterprise friction, not demo-day magic

LLM sampling

Token Analyzer

03

A visual inspection bench for the moment a language model chooses words: token candidates, scores, probabilities, and decoding parameters exposed step by step.

  • +Shows candidate tokens and probabilities across generation steps
  • +Explores temperature, top-p, top-k, and logprob behavior
  • +Useful for making inference feel concrete instead of mystical

relativity simulator

Frozen Stars

04

An interactive black-hole simulation about the gap between falling-object proper time and the distant observer time that never quite lets the crossing finish.

  • +Visualizes faller time, observer time, horizon distance, and scale
  • +Includes dramatic and realistic engines for learning at different speeds
  • +Pairs simulation controls with a written physics explainer

Background

Old web instincts, modern agent loops.

I started professionally with PHP and HTML, then moved into full-time JavaScript early enough that the path still needed explaining. The work since then has crossed Node internals, frontend frameworks, build tooling, Vue, React, AngularJS, and the long arc of browser application design.

The current center of gravity is AI-assisted software delivery: coding agents, harnesses, SDLC automation, and the practical question of how teams should safely let machines touch source code.

2008 -> 2014

Web + software foundation

Small PHP/HTML projects became professional development, then a shift into full-time JavaScript before that was the obvious path.

  • + 2008: small web projects
  • + 2010: professional work
  • + 2012: full-time JavaScript

2014 -> now

Enterprise systems

Large teams, long-lived systems, real delivery constraints, and the practical discipline that comes from building software at enterprise scale.

  • + 2014: enterprise solutions start
  • + continues through current work

May 2025 -> now

PQSE research

A serious speculative framework for consciousness, free will, and probability selection under physical law.

  • + paper and public site
  • + feedback and propagation phase

Oct 2025 -> now

Agentic SDLC

Coding assistants, harnesses, workflow safety, and the question of how teams let agents touch source code responsibly.

  • + main focus since Oct 2025
  • + VibEnv and agentic delivery systems
