    Extremely capable full stack web developer, also capable with mobile app development and desktop application development. 20 years of experience. I've made dozens of CMS-driven websites for top brands, including Jacuzzi, Sundance Spas, Celestron, US Storage Centers, SmartStop Self Storage, AllCare Health, FirstHealth, ICU Medical, and many others. Yes, their primary websites from scratch, not just some random landing page. I especially enjoy making websites performant (I can get very solid PageSpeed Insights scores, even while loading everything and the kitchen sink with GTM), and making websites accessible to those with disabilities (I've helped several websites attain great WCAG 2.0 AA compliance). I'm very comfortable working with CMSs (Content Management Systems), most especially Umbraco (a .NET open source CMS). I've also worked on Contentful projects, and I'm a Kentico Certified Developer. CMSs are second nature to me. I'm also happy and very adept at handling any website-adjacent tasks, such as complex customer data to HubSpot, database import/export/ingestion/sync processes, indexing and search (e.g., Lucene/Elastic), migrating from legacy platforms to new ones, calling complex APIs, writing unit tests, engineering sophisticated business logic, estimating tasks small to large, guiding teams, creating architecture diagrams, interfacing with clients and vendors, dynamic image manipulation and optimization, and generally solving every problem related to building software. Some project I created include: • Formulate. A very feature rich, open source form builder for Umbraco. • WiSKi. I created the Wireframe Starter Kit as a way to avoid reinventing the wheel on every Umbraco project. • Component Kit. I created component kit to avoid reinventing the wheel on frontend builds. • Dompiler. Like React/Svelte/AngularJS, but super tiny. • Rhythm Libraries. Built this collection of .Net and Umbraco libraries that was used across many websites. It had broad capabilities. Open sourced. I'm very comfortable writing. Including articles, answers, and forum posts, I have a footprint of about 20,000 distinct writing pieces. When you wonder, "who are these people that constantly answer other developer's questions," I'm one of the answers. I can build the entirety of the technical stack of your business. If you can dream it, I can build it, and I aim to build it well. Your goals are my goals.

    I've been a software engineer since 1980 and have written almost everything you can think of: A spreadsheet, wordprocessor, full accounting program, paint programs (vector and pixel), Email Client, Web browser (before Netscape existed), War Game Simulation for the Joint Chiefs, courseware to teach the Navy electronics, device drivers, Modula II and FORTH compiler, SCORM compliant courseware administration application, chess and other action and strategy games, a SCORM compliant web-based WYSIWYG courseware editor for the FBI, dozens and dozens of web applications for clients, and hundreds of smaller applications like a VPN client and mobile applications for Exxon/Mobil. My most recent endeavor was for a 25 person recruiting company where I built their entire workflow system, to include a Twilio based phone system, chatGPT/Claude based resume rewriting system, Google Drive interface, massive search capabilities, all within a step based workflow. See the Contact Management System for Recruiter item in my portfolio. I have at least 30 languages under my belt. Learning new ones just takes a few hours to get the syntax and a couple days to master. I've also managed several million dollar projects and teams of at least a dozen programmers. I've been heavily involved in Software Quality Control/Assurance, Software Risk Management, and instituting processes for several companies and their programming staffs. Worked with Carnegie Mellon's Software Engineering Institute to bring several defense contractors in the Washington D.C. area into the Capability Maturity Model. **** If I can help you in any way please contact me. ****

    Hello! I'm Shreshth, a seasoned software engineer. I've worked at Amazon, Tesla, and Chewy on various projects. Now, I've launched my startup where I've already led 50+ digitization projects in Web & Mobile Applications (WordPress, React Native, React.js/Next.js, Node.js, Java). At Tesla, in a 4-week timeframe, I led a project to consolidate and revamp an application for 20,000+ weekly visitors across 25+ diverse locales, supporting translations including right-to-left (RTL). The application achieved 91% for accessibility and 100% for best practices and SEO as assessed by Google's Lighthouse report. At Chewy, I found, diagnosed, and resolved a critical micro-frontend load time issue by implementing incremental caching with Next.js and React.js. This led to a drastic 75% reduction in backend costs and compute consumption leading to at least a 300% improvement in page load time, improving customer satisfaction and system performance. My education stems from the University of Washington, where I've studied Computer Science and Data Science. I've learned and worked with Software Engineering, Deep Learning, Artificial Intelligence, Machine Learning, Data Structures, and Algorithm Design. This solid academic foundation, coupled with my experience, has empowered me to work on impactful projects. But it's not all about the tech for me. I've always been a team player, and my ability to communicate effectively and work collaboratively was recognized by an Associate Director at Chewy. They said, "Shreshth demonstrated a great level of curiosity, dove deep into the problems and projects that he was given and did an amazing job of communicating his progress and keeping me in the loop. He fit in well with the team and was a big asset." I'm excited to bring this same level of dedication, curiosity, and commitment to your project. Let's create something amazing together!
