    I am a junior Computer Science student at San Jose State University, with a 4.0 GPA over 4 years. I have experience in Fullstack, Java, Python, and C++ development, as well as an ongoing interest in Math, Statistics, Data Science, and AI/ML. As a software engineer intern at Spectrum, Charter Communication Inc., I have built several full-stack web projects independently. Additionally, I have contributed to building the core client site of PureML startup as a software engineer. During my time at Presight.IO, I built an econometric simulation that integrated generated data into a machine-learning model, resulting in 70% accurate analyses for clients. This internship taught me how to conduct scientific research and build challenging innovations. In my opinion, hard work, focus, and a deep understanding of "learning" are the keys to excellent performance and learning any skills, tech stack, or areas in software engineering, computer science, and AI/ML. Whenever I receive a task, I put in the effort to dig up all the relevant resources and find the key to completing it, whether I've encountered a similar task before or not. This approach has been instrumental in my continuous learning and development.

    I have been focused on full stack development with Firebase since 2017. Details are below. Attached link is to a Flutter chat app, demonstrating a clean UI/UX implementation. I am looking for good assignments to work on. If my rate is an issue, I am open to discussing it. Beyond Firebase, I have experience with the following: - 15+ years full-stack/server-side design & development using NodeJs, Java, PHP - 5+ years Native Android in Java - 7+ years Test Automation design & development of test harness architecture using technologies including: Selenium, Appium, JUnit, TestNG, TDD FIREBASE EXPERIENCE Firebase backend features demonstrated across projects: - Firebase User Authentication for the Sign In - Majority of backend functionality is Google Cloud Functions code that runs on the server - Architecture where client simply provides the name of the function they want, and the data it requires - User specific data is stored in the Firebase Firestore "database"; and image content is managed through Firebase Storage - Security Rules configuration for Firebase Storage because this interaction is typically not handled by cloud functions, but rather directly from the client - Payment processing is implemented via Paypal-API Express Checkout, and a corresponding backend architecture to support tracking transaction history March 2017 - Nov. 2017 Deep-dive into writing Firebase client code for/from web browser and Native Java Android clients. Learning how to set up security rules and overcoming the challenges with that. January 2018 - Nov. 2018 Main site: storylabs.online Architect and sole developer of core platform. Complete design and development of entire back end architecture using cloud functions, storage, security rules, hosting. The cloud functions architecture is robust with clean well-organized code, effective error handling, and using proven patterns for interacting with the Firebase backend services - such as communicating with Firebase Storage. Web stack front end with JQuery, and backend with Firebase. PERSONAL FIREBASE PROJECTS **Links available upon request** Dec. 2018 - Feb. 2019 Firebase Backend Architecture for Chat App. This was more challenging than expected; thought it would take 6 weeks, but turned out be 12-14 weeks. Learned a lot on this one, built out a lot of good infrastructure to be used in the future. March 2019 - June 2019 Firebase Backend Architecture for PDF Generator. Front end is a web application to assemble text and image content that will in turn be assembled into a downloadable PDF report. July 2019 - September 2019 Firebase Backend Architecture for Ad Server. Front end is a web application to put together an ad campaign. Then on Android client, there is a native Android Library module that takes an app-id as input, sends a request of ads list to server, and gets that back to show in the mobile client. BACKGROUND SUMMARY I put great emphasis on quality in implementation and design; it is reflected in the work I produce, a clear communication style, and determination for meeting project release dates. My background includes: - requirements analysis to define project scope - tracking & maintaining steady progress - working well in a distributed team environment and across the enterprise - leveraging coordination efforts to produce solid high-quality code that fulfills project requirements - as needed, organizing efficient processes/methodology for various stages in the development life cycle - effective day-to-day knowledge-transfer (voice, screen shots, screen casts, wikis, etc) RESUME EXCERPTS May 2016 - May 2017 - Native Android Developer, at mobile app company (100 employees) Android development for multiple financial-sector customer apps. Implemented UI/UX using best practices around the MVP & Repository design patterns. APIs include: Dagger2, XML DataBinding, RetroFit/OkHttp. September 2014 - March 2015 - Web & Mobile Test-Automation Engineer Built Selenium tool suite & back-end infrastructure. Re-purposed Selenium tools to work with Appium Android testing.
