Full-Stack Software Developer

Building reliable web, mobile, and WordPress products.

I’m Joshua Lisojo, a New Jersey-based developer building secure, accessible products across React Native and Expo, WordPress and PHP, JavaScript, and Python APIs.

About

My Story

I’m Joshua Lisojo, a proud native of Perth Amboy, New Jersey, where I was born, raised, and still call home. During my junior year of high school, a life-altering moment occurred: I sustained a severe spinal cord injury while wrestling at a tournament for Perth Amboy High School. In an instant, I was paralyzed and lost the ability to walk. Today, I navigate the world with the aid of a motorized wheelchair.

Though my injury was profound, I chose resilience over despair. I believe everyone faces challenges, and life is about moving forward. With determination, I set ambitious goals, including earning a master’s degree. I pursued computer science at Kean University in Union, New Jersey, earning a B.S. in Computer Science in 2013 and an M.S. in Computer Information Systems in 2014, graduating magna cum laude.

My disability has not dimmed my intellect or ambition. As a developer, I face no barriers to producing exceptional work. My mission is to harness my skills to shape the future. Inspired by Ed Catmull’s words in Creativity, Inc., “The best way to predict the future is to invent it,” I’m driven to create innovative solutions. From my perspective—whether standing or sitting—the future shines bright.

Today, I build products across web and mobile, alongside production WordPress systems. Recent work includes Blunkle, a cross-platform social app in development, and Coqui Events and Coqui Events Pro, a WordPress plugin ecosystem I designed and released.

Featured Work

Independent Products

RAG Chatbot (Local & Hosted Models)

Python LangChain Ollama Groq FastAPI Chroma

A retrieval-augmented generation chatbot for asking questions over documents. It chunks and embeds source files in Chroma, retrieves relevant passages, and generates answers through a FastAPI service with configurable Ollama and hosted model providers. The local Ollama setup runs without API keys; the public demo uses a hosted LLM provider.

Coqui Events & Coqui Events Pro

PHP WordPress JavaScript Gutenberg

A WordPress event-management product ecosystem built from scratch. The free core plugin provides a custom post type, metadata, theme-overridable templates, Schema.org markup, shortcodes, and a native Gutenberg Event Grid block. The Pro add-on adds recurring events, occurrence exceptions, an AJAX calendar, iCalendar feeds, and a Gutenberg Event Calendar block.

Blunkle

React Native Expo Firebase RevenueCat

A cross-platform social app in development for creating and sharing paths and steps, with profiles, a personalized feed, media posts, discovery, and subscriptions. I co-founded the product and lead engineering across its mobile client, Firebase backend, and iOS/Android delivery workflow.
