SOHEIL AGHAYANI

Environmental Engineering, Research, and Software Architecture

A living portfolio that turns environmental research into interactive systems,
practical tools, and small experiments worth exploring.

The idea

This repository powers the personal portfolio of Soheil Aghayani, an environmental engineer and software developer focused on sustainability research, waste valorization, biofuel production, life cycle assessment, data analysis, and usable software.

The site is deliberately more than a list of credentials. It is a small interactive environment where the portfolio, research process, terminal, games, notes, and visual experiments share one coherent interface.

Interactive systems

Terminal

Open the Hello_World prompt or use the terminal trigger, then try:

help

thesis
thesis flowchart
skills
contact
play
play minesweeper
notes
screensaver
screensaver list
screensaver dvd

screensaver without an argument selects a random theme. Explicit themes include starfield, matrix, dvd, synthwave, and quantum.

Game Center

The launcher currently includes:

• Snake
• Blackjack
• Tetris
• 2048
• Minesweeper
• Breakout
• Space Shooter

Games are loaded on demand so the landing experience does not pay the cost of every game at first paint.

Research interaction

The portfolio presents research as a process rather than a single paragraph. The flowchart viewer supports pan, zoom, reset, focus-loss feedback, and keyboard or pointer interaction. The thesis content covers calcium oxide catalysts derived from waste seashells, waste cooking oil conversion, biodiesel production, and life cycle assessment.

Engineering profile

Track	Focus
Environmental engineering	Solid waste management, circular economy, biofuel synthesis, environmental impact assessment
Modeling and analysis	SimaPro, OpenLCA, LandGEM, GIS workflows, data processing, reaction kinetics
Software engineering	Python, C#, WPF, JavaScript, HTML, CSS, canvas-based interfaces, automation
Research practice	Heterogeneous catalysis, waste valorization, laboratory work, technical communication

Technical shape

The frontend is intentionally framework-free. It uses semantic HTML, custom CSS, modern browser APIs, and focused JavaScript modules rather than a large application runtime.

Local SVG icon system

Icons are part of the product surface, not a runtime dependency fetched from a font provider.

• Canonical SVGs live under assets/icons/.
• assets/icons/sprite.svg is the runtime sprite.
• assets/icons/manifest.json records paths, source categories, and duplicate decisions.
• js/icons.js exposes the shared IconRegistry for static and dynamically-created UI.
• UI icon fonts, pictographic emoji, and runtime external SVG downloads are not used.

After changing a canonical icon, rebuild the sprite from the repository root:

node tools/assets/build-icon-sprite.js

Read ICON_DECISIONS.md for the visual and licensing decisions behind the asset system.

Performance principles

• Keep the landing page useful before non-critical interaction code arrives.
• Defer heavy effects and game modules until they are needed.
• Use local SVG sprite references instead of icon-font downloads.
• Lazy-load game artwork and warm game modules during idle time.
• Use content-visibility for below-the-fold content where appropriate.
• Keep analytics opt-in and disabled by default in js/site-config.js.

Run locally

Requirements: Node.js and npm.

git clone https://github.com/Soheil-Aghayani/Soheil-Aghayani.github.io.git
cd Soheil-Aghayani.github.io
npm install
npm start

Then open http://127.0.0.1:8080.

The repository uses main as its single deployment branch. There is no frontend build step; the local server exists to provide correct static-file behavior during development.

Analytics and privacy

Google Analytics is disabled by default. To opt in for the deployed site, set a valid measurement ID in js/site-config.js:

analyticsMeasurementId: 'G-XXXXXXXXXX'

Local notes stay in the browser until explicitly exported. No analytics requests are sent from local previews or forks without a valid ID.
