LiveWeb ToolJavaScript
Circuit Load Calculator
Browser-based calculator for estimating electrical circuit loads. No frameworks, just HTML, CSS, and JavaScript.
Featured Work
Projects as a lab, not a link list.
Shipped tools, active experiments, and planned prototypes. Each card shows what it does and where to go next.
LiveAstroTypeScript
RolyPeraWeb Astro Site
This site, rebuilt from scratch with Astro. Component-first architecture, dark creative-tech aesthetic.
LivePrivacyClient-side
EXIF Photo Cleaner
Strip GPS coordinates, camera info, and timestamps from photos. Everything runs client-side, nothing leaves your browser.
LiveWeb ToolCDN
PDF to Images (CDN)
Lightweight PDF-to-image converter. Loads libraries from CDN so it stays fast — you do need an internet connection.
LiveWeb ToolJavaScriptData Analysis
Lottery Combination Analyzer
Browser-based lottery analysis tool for Custom Pick games, Powerball, and Mega Millions. Auto-loads built-in historical draw data for each game type, with paste/upload override support.
GitHubPythonAPI
Bitcoin Price Tracker
Python CLI tool that fetches live BTC/USD prices from CoinGecko. Color-coded output for the terminal.
In ProgressAIAutomation
AI Agent Workflows
Experimenting with Hermes Agent and LLM orchestration — automated workflows for development, research, and content generation.
WIPBlender3D
3D Scene Experiments
Blender models, procedural materials, and WebGL renders. Ranges from architectural studies to abstract compositions.
PlannedGame DevCanvas
Retro Game Prototypes
Small playable experiments inspired by classic game mechanics. Pixel art, simple physics, browser-based controls.
Lab Areas
One site, several technical tracks.
Each area is a technical track with its own projects, experiments, and notes.
WEB.DEV Web Development
Browser tools, calculators, and interactive apps. Clean code, practical interfaces, no bloat.
CODE.TOOLS Coding Tools
CLI utilities, scripts, and automation for the tasks I keep doing manually.
AI.LAB AI Experiments
Prompt engineering, agent orchestration, local models, and workflows that extend what I can build alone.
3D.SCENE 3D / Blender
Modeling, materials, lighting, and renders. From architectural studies to abstract visual experiments.
GAME.LOOP Game Development
Retro-inspired mechanics, pixel art, and small playable prototypes built in the browser.
OPS.AUTO Automation / IT
Infrastructure, monitoring, diagnostics, and the systems that keep everything else running.
Notes / Musings
Make the thinking visible.
Dev logs, design thinking, and technical write-ups. The process behind the projects.
AstroDev Log
Building RolyPeraWeb with Astro
How I migrated from WordPress to a static Astro site. Covers component architecture, design tokens, and self-hosted deployment.
DesignBlueprint
Creative Tech Lab — Site Redesign Blueprint
The thinking behind the new visual direction: dark creative-tech aesthetic, card-based layouts, and a design system built from scratch.
AIAutomation
AI-Assisted Development with Hermes Agent
Notes on using LLM agents for code generation, planning, documentation, and multi-agent workflows.
About Rolando
IT foundation, creative developer range.
I'm Rolando Pera. I work across web development, automation, computer graphics, and AI — building tools, experimenting, and documenting the process. This lab is where that work lives.
The projects range from practical utilities — circuit calculators, price trackers — to creative experiments in 3D and game design, plus AI workflows that extend what I can build alone. Everything here is something I actually use or want to learn from.
