    I specialized in third-party API integrations and building web applications. What I offer: - API Integration with any 3rd Party systems - Building custom web applications from scratch - Solving any Golang related task - Consulting clients with anything about the technology and helping them find the best solution for their problems My API integration expertise and some projects I worked on: I wrote software solutions for syncing orders, products, customers, categories, and other resources between e-commerce platform APIs and different ERP APIs. Also, I integrated many financial schemes through their APIs, like RT1, SEPA, Faster Payments, SWIFT, etc., to allow banks to safely exchange money in real-time on the Internet. Besides that, I used many other systems with well-known public APIs like Stripe API, authorize.net API, DHL API, Slack API, etc. Besides API Integration, I have expertise in building web applications using Golang. I've built many web applications from scratch based on Golang. Some of them: Custom CRM software, Veterinary management software, Rest API testing services, Warehouse management software, and many more. Consulting clients about the technology and finding the best solutions for them is also what I am doing. If you are a business owner with little experience in IT, I can advise you on how to digitalize and automate your business processes. In general, I have experience with 14+ years of building complex systems and microservices in various technologies, such as Golang, Java, PHP, Ruby, Javascript, Vue.js, Docker, Kubernetes, AWS, etc. I've worked for years in agile cross-functional teams. I had different roles and responsibilities, such as developing, deploying, monitoring software, modeling databases, and leading engineers. I pay a lot of attention to testing and firmly believe that automated tests are essential for every software.

    Hello Upwork Community! Thank you for taking the time to read through my bio, I started actually just like you as an Upwork client so I know exactly what it's like to run projects and look for that perfect freelancer that can really provide value to what ever problem you are trying to solve. As I did not always had the financial recourses in my younger days I ended up often solving difficult problems by myself instead of hiring a freelancer which has helped me tremoundusly gaining a diverse set of valuable skills. My professional career has been very finance oriented having worked at Fintech startup as a Software Engineer focused on Full Stack development ( HTML, CSS, JS, Python (Django)) to then transition into more Quantative focused positions at Bloomberg and SaxoBank. In my roles as Quant and ML engineer, I have been mainly focused on building predictive models for a variety of business applications. (Algorithmic Trading, Risk Management, Fraud Detection, Asset Price Prediction) with the main tech stack being R and Python. The main ML Frameworks I have extensive experience using are the following : TensorFlow, Scikit-Learn, Keras, Pytorch, CNTK, Gradient Boosters, Apache. Additionaly I have always been busy on the side working on various sportsbetting projects, again building predictive models on different sports such as Soccer, Horse Racing, Basketball, Baseball and the list goes on. I'm definitely no stranger to developing and managing large database structures cloud or on Premise using either SQL or NoSQL type of databases. So where can I offer real value to you? 1. Building attractive and responsive websites 2. Solving business problems through leveraging machine learning frameworks 3. Anything investment/finance related that eyes Algorithmic trading, Risk management and Idea Generation 4. With sportsbetting applications that involve computing probabilities on the outcome of different sporting events. Look forward to hear from you soon and don't hesitate to reach out if you have any questions. Best, Oskar

    Welcome to my profile on upwork! I am a python developer, specializing in automated web scraping using the scrapy framework. As a curious person by nature, I've spent a lot of time diving into the technical details of how the web works, and I've used this knowledge to automate data collection tasks for a variety of personal and professional projects. I'm highly intrigued by understanding how a given web server works and how web scraping can be leveraged to efficiently and robustly extract the necessary data for your projects. For example, this may include automating HTTP requests, directly accessing the internal API, or interacting with the frontend using a virtual browser instance. I received my Bachelor's in Computer Science from Humboldt University Berlin in 2021 and have since been working as a software developer at Charité Berlin's Brain Simulation Section, as well as on a number of projects as a freelancer. To ensure that my work will be easy to maintain and extend, I focus on writing clean and concise code that adheres to modern formatting standards and best practices. I look forward to hearing about your project! For further reference, feel free to visit my github page on github.com/mahathu.

By building a high-stakes agency in the Game Creation industry, I'm equipped with everything it takes to build enterprise game solutions. Day in and day out, we make our clients happy and keep them in the loop on what me and my incredible team are crafting. I'm proud that we can deliver the best graphics for your games, apps, and programs due to a close and long-lasting partnership with Fardo Studio.

    I'm an expert full-stack developer for Java web applications and dynamic frontends, preferring Spring Boot and Angular as the best combination. Spring Boot combined with an Angular frontend, is the base of the most successful web applications in the long run. I'm a developer with over 20 years of experience building professional web applications for all-sized businesses. And the projects made with spring and angular are the projects that run for YEARS! I have worked with Java since 1997, focusing more and more on web development and mainly on the backend. Spring Boot was the most important invention since sliced bread, and Angular is THE perfect match. There is a reason why this concept has been copied so many times, for example, with NestJS in the nodeJS world or Symfony in the PHP world. I work with the type of business owner who cares about quality and their long-term investment because you know getting A+ work will put more money in your pocket. If that sounds like you, and you want to know you're squeezing every dollar out of the effort you've put into your business, I'm the right guy to help. Professional: Computer Scientist Software Architect Languages: German (native speaker), English (fluent), Netherlands (beginner) Year of birth: 1968 Professional Focus: Spring Boot, Angular, REST-Services, Docker, μServices, LowCode & RAD development Development methods: SCRUM, CI/CD, Test driven development, Model driven development Web-Technologies: Angular, TypeScript, jQuery, HTML 5, CSS 3, BootStrap, openAPI Backend Technologies: Sprint Boot, Spring 5, Tomcat, JBoss, GlassFish, Apache2, Docker, Micro-Services, REST-Technologies (Jersey, Spring-MVC, SparkJava, JavaLin), Container-Platform, Enterprise-Sever (J2EE) Development Platforms I used/using: IntelliJ, Eclipse, Visual Studio Code, Xcode, Gradle, maven, ant, Jenkins, git, GitHub, cvs, Visual Paradigm, MagicDraw, make, emacs, vi, Unix-Tools (bash, sed, awk, grep, etc.) Special knowledge: VP/MS-Java-API, eBay-API, PayPal-API, building compilers, HBCI (German banking interface), Nonlinear Optimisation with simulated annealing, Solidity, Ethereum

    I am an expert C# developer, with over 9 years of professional experience with .Net Framework and more recently Dotnet Core. I have worked with multi-million pound online retailers, international airlines, and multiple large insurance brokers. I mainly work on web applications specifically ASP.NET MVC (my preference is for dotnet core) using Web API + MVC + React/Typescript front ends. I use C# as the business layer and various databases (SQL Server, MySQL, Postgres) using Entity Framework (or ADO.NET if necessary) as well as Document Stores (NoSQL) such as ElasticSearch and DynamoDB to greatly enhance the speed of applications. I am not limited to web, I have spent nearly as much time in the offline world scripting in C# in Console application, UWP and WPF. I have automated build pipelines using Cake (C# MAKE) and Warehouse Automation Stations using WPF applications. I also make command-line applications in Windows Powershell and Bash to automate things like database provisioning, data loading/transformation, and automating business tasks. I have worked on projects large and small, whatever they are I enjoy getting results, completing projects successfully and saving businesses time and money.

    I deliver your dream! I'm a seasoned IT-Project-Manager with in-depth management methodology AND technology knowledge. I helped multiple companies to make their visions reality. My experience ranges from Stock Exchange companies to side hustle Start-Ups. I'm very experienced in all aspects of Software Development projects. Technology-wise, I specialized in migrating or creating stuff to the most modern cloud technologies (serverless computing, PaaS, SaaS, IaaS) and was always successful in providing my customers with fewer operations costs and more features than expected. Management-wise, I have a strong track record of leading small to big, often not co-located, and international, heterogeneous teams to success. Of course, I hold the certifications to prove my broad knowledge of (project) management techniques (including PMP and PSM). In the past, I worked for DAX (German Stock Exchange Top 50) companies, small internet agencies, well-known local computer game developers and event managers, and Start-Up companies from all over the world. My philosophy is that I'm not going to pamper you more during the offer phase than I'll do afterward. If you want honest consulting, reliable deadlines, clear/open communication, and a job executed to fit your expectations, I'm your man.
