Open-Source Tools for Technology, Finance & Astronomy

Building and sharing at the intersection of technology, finance, and astronomy. Open-source tools, real experiments, practical results.

About This Site

I work on small to medium-sized projects, write short how-tos, and share data analyses. The goal is to make knowledge tangible: fewer buzzwords, more substance – with code, numbers, and clear visualizations.

Focus Areas

🖥️ Technology

Software tools, security analysis, and automations – from web apps and security utilities to infrastructure and scripting.

Why? Solving complex problems with clean code – transparent, open-source, and free for everyone.

Typical content:

  • Security tools, data analysis, automations
  • Open-source projects with documentation

⭐ Featured: Unicode Security Analyzer – detects invisible characters, steganography, GenAI fingerprints, and phishing attacks in text, emails, and URLs.

📈 Finance

Data-driven perspective on markets, risk, and personal financial planning.

Why? Better decisions through methods instead of opinions.

Typical content:

  • Portfolio concepts, backtests
  • Cost traps, simple dashboards

⭐ Featured: Portfolio Wizard – with Parqet integration – & Monte Carlo Simulation. Built in TypeScript with React, deployed to AWS – free to use.

🔭 Astronomy

Observations, data, and small instruments for exploring the cosmos.

Why? Curiosity about the bigger picture.

Typical content:

  • Observation reports, image processing
  • Equipment, celestial events

⭐ Featured: Svenesis Siril Scripts – my open-source Python tools for astronomical image processing. Several are included in the official Siril Script Repository; all are freely available on GitHub.
