About

I’m Saul Ramirez, and I’ve been working in the IT industry for almost 11 years. I started out as a web developer, learning Dart, JavaScript and C++. But my skillset didn’t stop there – I also learned Solidity and am familiar with React, Angular and Flutter frameworks/libraries.

I consider myself a fullstack developer, and have worked on MERN (MongoDB, ExpressJS, ReactJS, NodeJS) projects extensively. However, I don’t shy away from MEAN (MongoDB, ExpressJS, AngularJS) projects either.

My experience as a software developer and my knowledge in the mechanical and electrical fields helped me create an innovative energy monitoring system. This photovoltaic platform monitors plants that produce clean green power with unprecedented precision, supporting RER Energy’s ability to deploy new projects faster and more efficiently. Career Progression I began as an entry-level software developer, tasked with creating a new data manager to monitor systems using embedded devices like Raspberry Pi. This required designing Flutter applications for Android and iOS, enabling real-time access to critical data from anywhere, at any time. During my career, I took a break to join Headspace, where I gained valuable experience in software development and collaboration with high-performing teams. Upon concluding my tenure there, I was requested to return to RER Energy, where I was promoted to Lead Developer and eventually to Technical Manager. In this role, I significantly enhanced the company’s energy monitoring and management capabilities. Key Responsibilities & Achievements 🔹 Managerial Leadership Managed a cross-functional team of 8 developers: 5 Flutter developers, 1 React developer, and 3 backend developers, ensuring collaboration, efficiency, and high-quality deliverables. Acted as the Technical Manager, prioritizing tasks, coordinating development efforts, and ensuring alignment with RER Energy’s photovoltaic (PV) project deployment needs. Streamlined workflows using Asana for task management and Google Docs for documentation and communication. 🔹 Technical Leadership Led the development of a scalable cross-platform energy monitoring system using Flutter, enabling vendor-agnostic integration to monitor photovoltaic plants effectively. Improved project delivery timelines, reducing deployment times for PV installations from 4-5 months to under 1 month. Transitioned state management from BLoC to Riverpod, adopting a more maintainable and scalable architecture, speeding up development and reducing maintenance time. Integrated the OpenAI API to automate report generation and simplify energy data analysis with AI-driven insights, enhancing decision-making capabilities. Built a robust CI/CD pipeline using GitHub Actions for: • Automated deployments to TestFlight (iOS), Firebase App Distribution (Android), and Vercel (Web). • Generating Raspberry Pi-compatible bundles to support embedded systems. Fostered a culture of quality by implementing unit tests and widget tests, ensuring reliability and consistency across platforms. 🔹 Impact on RER Energy Enabled scalable and flexible system deployments, allowing seamless integration with multiple vendors and hardware options. Reduced photovoltaic project deployment times from 4-5 months to under 1 month, drastically improving operational speed and flexibility. Leveraged AI tools to simplify reporting, improving clarity and understanding of complex metrics. Key Skills Technical: Flutter, Dart, Riverpod, OpenAI API, Clean Architecture, CI/CD with GitHub Actions, TestFlight, Firebase App Distribution, Vercel, Unit & Widget Testing, RESTful APIs. Tools: Android Studio, Xcode, Asana, Google Docs, GitHub. Managerial: Team Leadership (8 devs), Task Prioritization, Process Optimization, Cross-Functional Collaboration.

During my tenure at Headspace from October 2022 to January 2024, I held a pivotal role in the client-side development of Headspace Care, where I was instrumental in introducing new features and refining existing code. My work encompassed content creation utilizing Gatsby and React, as well as the development of a bespoke internal marketplace employed by Headspace, crafted with React (JSX). A key aspect of my role involved the consumption of REST APIs built with Python (Django). In my capacity as a Senior Mobile App Developer, I spearheaded the design and implementation of innovative mobile applications aimed at enhancing user well-being and mental health. Leveraging Flutter as my primary development tool, my responsibilities extended to: Designing and developing highly functional and visually appealing mobile applications, ensuring an outstanding user experience. Collaborating closely with cross-functional teams to conceptualize and implement mobile solutions aligned with Headspace's vision and goals. Employing agile development best practices to ensure the efficient and effective delivery of projects. Contributing to the development of a robust, maintainable, and scalable architecture, thereby optimizing application performance and usability. Continuously maintaining and enhancing existing applications, integrating user feedback to improve functionality and user experience. Providing mentorship and technical leadership to junior developers, fostering an environment conducive to learning and professional growth. My contributions at Headspace were focused on creating mobile solutions that not only met technical requirements but also made a positive impact on the mental and emotional well-being of users.
