    I’m a data scientist who has experience across the gambit of data. I've worked as the first non-founder startup engineer in a data scientist and full stack developer role while supporting the growth from 0 to 10,000+ users. For another early-stage company, I developed processes to extract 100k's of textual summaries using automated and human in the loop processes to support their initial product launch. I’ve also worked as a data engineer at Capital One where I led the development of a distributed scheduler and execution framework that was ultimately patented. Also at Capital One, I worked as a data analyst and gave presentations using complex d3.js visualizations to C-level executives to help reimagine what data products could be at the company. With my diverse experience, I strive to create practical solutions and set realistic expectations. All while taking into account the short and long-term needs of my clients.

    Experienced and energetic Swiss software architect/senior engineer and AWS Certified Solutions Architect with a passion for designing and implementing innovative and state of the art systems in complex business environments. During my work in a Swiss private online bank I’ve taken the lead on and participated in complex projects with strict requirements such as event driven architecture in banking clients onboarding workflows, refactoring of authentication systems, translating business needs into architecture and apis from the design phase to the deployment and maintenance. My soft skills helped me organize and manage meetings with IT, businesses and other teams to improve our collaboration on projects, overall interactions and workflows. I also trained some newcomers to help them quickly understand our business and processes. My experience as an DevOps engineer allow me to see further than the typical developer world and to be independent in setting up, provisioning, templating, configuring, monitoring and maintaining infrastructure, middlewares and deployment and continuous workflows. On the front-end side I’m versed in React/Redux/RxJs to develop modern and reactive, simple and complex web applications. As a freelancer I worked with smaller companies to develop various systems such as a distributed caching engine with distributed rate limiting, a system to stress test different Java frameworks and Redis libraries and some frontend + backend systems to address specific companies needs in various languages using AWS Beanstalk, EC2, Fargate, ... I also have a keen interest and experience in new and interesting technologies and trends such as reactive programming, Kubernetes, algorithmic trading and cryptocurrencies/NFTs as my experience and personal/professional projects on Github demonstrate.

    I have more than 4 years of experience in Scala ecosystems like Spark, Akka, Play, Cats, http4s, etc. I love writing code in the functional paradigm, and I have experience designing and implementing services with a reactive manifesto. A part from it I started learning Rust and Kotlin.

    I am a developer with 8+ years of experience in mobile apps development. Some of the client feedbacks for your kind reference, which I think, would align with your requirements. **Understanding my clients, This was Stable Guard app for MagicAI, a startup with a seed funding of $1.2 million:** "We had Anuj porting a web app to an iOS swift app. The app was very well done. The aspect of his work I appreciated the most was the fact that when we would give him deliverables overnight (we didn't overlap much in terms of times), he would get the work done with general instructions, instead of requiring detailed instructions for every little task. This sped up development immensely. The work was good quality, and our app successfully launched. We will be utilizing him again for future updates as well as future applications." **Problem Solving Skills:** "Anuj is a skilled Android developer and problem solver. There was good clarity in communication and very reasonable turn-around on work. Recommended!" What Can I help you with: Services: - Native app development (iOS / Android in flutter and react native) - Custom app development (iOS / Android in flutter and react native) - App UX/UI design (iOS / Android) - App porting (iOS / Android in flutter and react native) - App testing (iOS / Android in flutter and react native) - Apps upgrade and maintenance (iOS / Android in flutter and react native) Here's a small list of my skillset:

    Attention: Please make sure to read the addendum. I am a web developer and freelancer technical writer. My writing is clear and easy to follow and understand. Also, as result of my technical background with a degree in Information Technology, a Nanodegree in Mobile Web from Udacity and current job as a developer, I am able to convey technically accurate information since I understand what I am writing about. My specialty lies in writing code tutorials, documentation and explaining technical concepts for a non-technical audience. Like I mentioned earlier, I have a B.Tech in Information Technology and a Nanodegree from Udacity. I have also successfully completed Amber Isrealsen's Course on Technical Writing. I am competent in the following programming languages and web development areas: C#, Python, JavaScript, HTML, CSS, React, NodeJs and ASP.NET MVC. My language of instruction and communication is English and I am a native speaker. My react article on Creating a Medium Post Widgets on Medium has gained wide traction with over 1000 reads and me receiving feedback on its content from readers of the world. You can find in the 'Other Experiences' section of my profile If you like that, then you'd like some of my other work. So let me help you create technical content that will be easy to understand and tutorial that are easy to follow for your readers. I look forward to working with you. Re the plagiarism feedback: Unfortunately, I cannot give a rebuttal because I missed it when he posted it and the deadline passed. However, I have the following to say: 1. His submission was quite dishonest and frankly exaggerated. I successfully delivered 4 articles with no issues and minimal edits which he managed to gloss over. The difference between the 'reworked' article and the parts of the allegedly plagiarized article I submitted is non-existent. Thus, it makes his accusation of plagiarism malicious and false. I can show you if you want. 2. I use CopyScape to ensure authenticity of my work and I always get a 100% plagiarism-free report. 3. I currently have 2 running jobs with clients who have no issues with my work so far. So please do not let that deter you, feel free to reach out. I am a delight to work with.
