Eric Gaspar
Full Stack Software Developer | Mobile & Web
Category : Mobile development
I’m a full-stack engineer with a strong track record of taking complex ideas and turning them into clear, dependable software. My experience spans mobile app development with Flutter and Dart, backend engineering with Python using frameworks like Flask and FastAPI, and modern web development with JavaScript, React, Redux, and Expo. I enjoy working across the entire stack, whether I’m building a new feature from scratch, strengthening an existing system, or stepping into a difficult codebase that needs careful untangling.
In my current role, I develop backend microservices and full-stack applications for a range of clients, which has given me exposure to many different industries, product goals, and technical challenges. I’ve built and maintained APIs for event-driven platforms, designed data models, and written thorough test suites to help catch issues early and support stable deployments. One of my more impactful contributions involved creating a prototype content-protection system using JavaScript on both the client and server sides—a project that helped a company secure funding by demonstrating the technical viability of their vision. I’ve also spent significant time improving older or rushed projects by reorganizing them into cleaner, more modular structures, making ongoing development noticeably smoother.
My background also includes direct collaboration with executive leadership. I’ve worked closely with a CEO to analyze a client’s existing technology stack and communicate the state of their systems in a way that supported strategic decision-making. I frequently work with third-party APIs as well, integrating data from platforms such as YouTube and Plex into custom software solutions.
I’ve completed several end-to-end projects that showcase my ability to take an idea from concept to functioning product. For example, I built a Reddit-focused tool that pulls posts from multiple search queries, stores them in a structured SQLite database, and presents them to users through a custom React interface. The backend includes a Flask-based API with authentication to manage user sessions securely. In another project, I created a registration management tool for cycling events, complete with a SQLAlchemy-powered REST API and a clean React frontend for organizers to use.
I’m no stranger to jumping into difficult situations. I’ve navigated poorly documented setups, resolved intricate state-management issues, handled race conditions, stabilized authentication flows, and restored critical functionality in mobile and web apps. I’m comfortable working independently, but I’ve also developed strong communication and teaching skills through my parallel work as a Muay Thai instructor—where clarity, structure, and patience are essential.
I approach every project with curiosity, discipline, and attention to detail. If you’re looking for someone who can build reliable software, diagnose tricky issues, or help bring order to complicated systems, I’m ready to help you move your project forward.
