I explore computer science, artificial intelligence and web technology by experimenting with useful browser-based tools.
I'm interested in computer systems, software development, AI and practical problem-solving. This portfolio is a space for learning, experimenting and documenting small tools. The projects are learning demonstrations built with coding assistance, not claims of professional experience.
Explore browser interfaces, interactive tools and accessible design.
Learn how parsing, algorithms, data transformation and text processing work.
Test edge cases, explain limitations and iterate on what I learn.
Eleven interactive experiments: six developer tools and five original browser games. Everything runs locally in your browser, without accounts, uploads or external APIs. Each tool includes a short technical explanation and limitations.
Validate structured JSON, pretty-print or minify it, and inspect its structure.
How it works: JSON.parse validates the input; recursive traversal counts nested keys and values. Invalid JSON produces a parse error.
Write a small Markdown document and see its live HTML preview. The renderer escapes raw HTML before applying supported Markdown formatting.
Supports headings, paragraphs, lists, bold, italic and inline code. This is an educational subset, not a full CommonMark implementation.
Explore small CSV datasets. Search records, sort columns, and calculate statistics for numeric columns.
CSV parser handles quoted fields, commas and newlines. Intended for small datasets; all data stays in the browser.
Test JavaScript regular expressions, highlight matches and inspect match positions.
Patterns run against text you provide. Very complex patterns may be slow; use short inputs and avoid untrusted expressions.
Watch insertion sort or selection sort reorder a shuffled array, one operation at a time.
Insertion sort builds a sorted prefix; selection sort repeatedly selects the minimum remaining value. Both are O(n²) in the worst case.
Test foreground and background color combinations for readable interfaces.
Contrast is calculated from relative luminance. WCAG AA thresholds: 4.5:1 for normal text, 3:1 for large text. Contrast alone does not guarantee full accessibility.
Original mini-games with keyboard and touch controls. Play without accounts, downloads or tracking.

Play now →I start with a small practical problem, experiment with an implementation, test different inputs and document what works. These tools are educational prototypes. The code is in this page's source, and visitors can inspect it using their browser's developer tools.
Try malformed JSON, quoted CSV cells, empty text and different color combinations.
Some features are intentionally simplified. For example, the Markdown renderer supports only a subset of syntax.
Explore automated tests, modular JavaScript and better keyboard accessibility.
