Hi, I am Robert A. Paulino

A Software Engineer.

I am a passionate student with a growing interest in backend development. I enjoy building efficient, scalable systems and exploring how technologies work under the hood. My focus is on projects involving APIs, databases, and server-side logic. I’m always eager to take on new challenges, expand my skills, and contribute to impactful projects.

Projects

Web Crawler

A high-performance web crawler written in Go that traverses websites concurrently, staying within the target domain and extracting internal links. It features a modern HTMX-powered web interface and supports exporting results to CSV. The crawler also performs in-depth SEO analysis, reporting key metrics like page titles, meta descriptions, H1 tags, word count, and link structure. Designed with flexibility in mind, it allows configurable concurrency, crawl limits, and supports both CLI and web-based operation.

Security Dashboard

BlueWard is a mock frontend dashboard designed for managing resident and guest check-ins at a multi-house residential facility. Built with React Native for cross-platform support, it offers tailored dashboards for four user types: residents, guests, security guards, and admins. Key features include invite management, check-in/out tracking, multilingual support (English and Spanish), and a clean dark theme UI. This project served as a prototype and proposal for a future full-featured application.

CHIP-8 Emulator

Go-R8T is a terminal-based CHIP-8 emulator written in Go, built to run 1970s-era CHIP-8 programs and games. It supports the full instruction set, features a flicker-reducing phosphor display effect to enhance visual experience, and offers intuitive keyboard mappings for seamless gameplay. With a simple ROM loading process and clean architecture (CPU, memory, display, and input modules) simulating that of a real CHIP-8, it served as both a functional emulator and a learning tool for low-level systems programming.

Geocoding API

This project represents the open-source iteration of my geocoding API, engineered to provide precise geospatial analysis by translating addresses into geographic coordinates and verifying their presence within polygonal boundaries provided by shapefiles. With the use of GeoPandas, this API reads and processes geospatial shapefiles, while the Google Maps API efficiently converts physical addresses into accurate longitude and latitude pairs. The server-side integration of shapefiles facilitates advanced spatial queries and would allow to further develop it into more a more complex API.
