    I was trained classically, writing C and C++ code for Wall Street trading powerhouses like Goldman Sachs and Lehman Brothers. Running on advanced Unix systems, these lightning fast applications pioneered the field of today’s realtime global Fintech. As the Internet spawned open source platforms like Linux, MySQL, NodeJS, and AWS Cloud API’s, my skillset evolved into a full stack portfolio, where I built powerful back-end server software and the front-end web portals to deliver large, complex datasets via intuitive web portals. The maturing of JavaScript as the main language of the web, both on the front and back ends, has validated my decision to adopt NodeJS as my main coding platform in 2011. Today, JavaScript forms the glue of most of my applications, running on Node on the server, and in the browser up front. After moving to the West Coast in 2016, and spending time in Silicon Valley, I ventured away from financial systems to innovative applications like Blockchain Protocol coding and Video Streaming/Ffmpeg. I also coded network traffic optimization software down to the fundamental layers of the TCP/IP stack. All these big data applications naturally led me into the design and coding of custom algorithms. Whether compressing/chunking a video stream to play on a low powered mobile device, parsing network packets for suspicious traffic, or generating large NACHA files, the ability to code an algorithm in plain C can make the difference between a successful production deployment, and non-performant code that never leaves the github repo. From my early career, I have made Database structure the centerpiece of my application design. Again, classical training in Dr. E. F. Codd’s model of Relational Databases has always informed my philosophy of how to structure an application’s data repository. With web-scale data, this field has grown to NoSQL and Graph databases. Now, huge datasets underpin the training of AI/ML models. I have kept my skills updated on these data technologies, and I combine the relevant elements of each to define the most appropriate data repository for my software.

    I have started developing web extensions in 𝟮𝟬𝟬𝟳 on Firefox. Since then I have created and contributed to more than 𝟲𝟬 private and public 𝗰𝗼𝗺𝗽𝗹𝗲𝘅 browser extensions with 𝟭𝟬𝟬% success rate in domains as varied as lead sourcing, reputation management, cashback programs, process automation, browser security etc ... I am a problem solver and I love working on complex architectures and solutions. Throughout my development work, I have solved key issues specific to Chrome extensions such as: ✔️UI cohabitation with web page content ✔️responsibility split between extension and web app ✔️ in-browser optimization. ✔️ advanced web page processing (scraping, interception, image processing) I can assist you with various aspects of the extension lifecycle: - consulting (project assessment 360°) - PoC/MVP product development - fractional CTO/technical lead (including manifest V3 migration) - extension expert staffing My favorite stack: - typescript & webpack - UI: REACT, vuejs, jquery, materialize, bootstrap, - DBs: mySQL and Firebase/Firestone Databases - APIs: Google APIs, chatGPT, Zoho, Bullhorn and many others ... - Selenium for automated non-regression testing - Google analytics for fix&feature development prioritization, A/B testing - wasm for speed optimization - openCV for image processing etc etc ... Some of my projects: - the Papermill Alarm (in progress): just completed an extension providing researchers with fraud assessment while reading publications on the web. Uses Auth0 and Stripe SaaS services to authenticate and bill users. - Clipflip: screen recorder (similar to Loom). Designed the extension and also the ffmpeg-based media engine running on the backend of the solution. - totalRecall (personal project): an extension similar to getpocket.com to archive and manage your critical web content, hooked with openAI API to auto-classify content. - Kagi apiTester (private chrome/FF extension): automated web extension API testing environment for an alternative browser called Kagi. - Videonotebook (public chrome extension): note-taker which helps you remember more from your videos and meetings. - ExecVision conference recorder (public chrome extension): enables users to record meetings (meet, zoom, webex etc ..). - The Social Lead Machine (public chrome extension): linkedIn data extraction and profile search automation. - Password Depot Extension (public chrome extension & Firefox): centralized password management. - Masterkey (public on chrome store) : automatic login and user review response for reputation management. - TheWalk (private extension): automatic bidding system used by a team of 8 operators for ticket purchasing. - Portico (dead project): developped an automation extension posting properties on 3 major real-estate indian portals. - SpeedCRM (private Firefox extension) is a greasemonkey type of extension which tailors Salesforce CRM to specific organization requirement and boosts user-productivity. FinaIly, I follow closely the WebExtensions Community Group (led by Google, Mozilla&Apple) to stay fully aware of the latest Web Extension moves and run a technical blog at browserextensionresources.blogspot.com to share my experience.
