🥇 Top Rated Plus Contractor since 2020 🥇 10+ years of professional experience 🥇 98% Client Satisfaction Rate 🥇 350+ real stores built on Shopify in the last years 🥇 Ex Silicon Valley Designer and Software Engineer Hello, if you came this far, I know you are tired of jumping from freelancer to freelancer, so hear me out: Right now, the eCommerce with Shopify is highly competitive. The margins for ads are getting thinner as big brands drive the cost of ads up. On top of that, you are up against companies with fully-fledged teams in marketing, development, and design. So tell me: how will you compete hiring a cheap freelancer that is good at only one thing? You won't. Chances are you have been here before and tried to hire someone, and that didn't go well. Maybe the freelancer could design but not develop or develop but not design. Maybe you hired a team and tried to become the project manager, only you don't know how to do that and managing developers is horrible, so it failed. It's always like this...the freelancer doesn't communicate properly, has no set process and you are basically rolling the dice every time you make a hire. The good news is that after working with 7-8 figure brands I've found a solution. These brands have figured out that you can outsource whole divisions of your company to highly specialized agencies. They do that with marketing, design and development, and even customer support. I'm not talking about the classic "I do everything" agency. I'm talking about smaller operations that hire and train people to do specialized work. In our case this is Shopify. Now that is probably a few hundreds per hour, right? not necessarily. You see, a freelancer charging 40 an hour can take triple the time of an agency charging 80 and doesn't offer the quality and level of service an agency can offer. The difference is that you can have a designer, project manager, tester, and developer for that 80 an hour for example. After working in Silicon Valley with 8 figure eCommerce brands, I went out to build my own agency to do just that: take the pressure off design and development and help your business grow. We have worked with hundreds of companies and got to top-rated plus (top 1% of upwork) in less than a year. What we have built is a fail-proof process to ensure projects are successful no matter your size. Stop gambling, its time to find a long term partner that can recommend strategies and do the heavy lifting for you. Hit that green button and lets talk to see how we can help you.

Generating a lot of data but not making sense of it? Overwhelmed by the latest trends in Data Engineering and Artificial Intelligence? Need someone who can speak in business terms while also having strong technical expertise? I've been working with Upwork since 2016, and am proudly part of the top 1% (Expert-Vetted) program. I've built the information structure of several companies across the globe in Marketing, Financials, E-commerce, and Agribusiness - regardless of their size. I've worked for 1000+ employees companies and small shops accordingly. I usually report directly to the CEO as CTO/CIO, to the C-level as data lead, or can also act as a team player - brain for hire for bigger teams. I like all kinds of challenges. What I can do: - Take your raw data, process and present it in a meaningful and reproducible way. My goal is to keep you aware of what's happening (in plain language, if you're a non-tech person) and to work together with your team (if you already have a tech structure) on every step of the process - from data extraction to final presentation. - Create (or advise you on how to build) new interfaces to update your existing systems with insights and KPIs derived from Business Intelligence and AI projects. - Suggest the best course of action and best practices for your situation. No matter your size. - Audit your existing information structure and point you to new possible revenue sources or cost reductions. If that resonates with what you need, get in touch. I'm always happy to help. For those techs out there, I usually work with: - R - Python - QlikView / QlikSense / QlikCloud - PowerBI - Tableau, But I've also worked with Klipfolio, Chart.io, and many other tools. I've developed interfaces and APIs for - OpenAI (ChatGPT) - Ai-Pro (Claude) - Google Analytics - SAP R/3 and HANA - Unleashed Software - Monday.com - ZOHO CRM and Campaigns - InfusionSoft - ActiveCampaign - GIS tools (ArcGIS, QGIS, PostGIS). What I also do: - Snowflake, Amazon & Azure datawarehousing - SQL querying and tuning (MySQL/MS SQL Server/PostgreSQL) - Big Data processing - Forecasting models - Marketing effectiveness analysis

With 15 years of experience in computer graphics, I am a seasoned developer who is passionate about computational geometry and engineering problem-solving. My expertise includes analyzing CAD models, allowing users to measure and verify their manufacturability. Additionally, I have leveraged computer graphics to create engaging e-commerce experiences, such as loading products onto the browser, enabling users to interact, customize, and augment them before purchasing. My technical skillset is extensive, encompassing both STEP/IGES models and mesh models in the form of STL/OBJ. I am proficient in programming languages such as C++, C++/CLI, JS, and C#, and UI tools like QT and MFC. I have worked with various geometrical kernels such as Para-solid, Open cascade, CGAL, and IGL, as well as graphics basics like VTK and OpenGL. Moreover, I have created 3D configurators that allow users to customize and augment products in real-time and make purchases directly through the website. I am well-versed in using JavaScript libraries and WebGL/Three.js to create engaging and interactive experiences that enhance the user's engagement with the product. My experience in e-commerce and computer graphics has enabled me to create innovative solutions that make businesses stand out in a crowded marketplace. I continuously explore new technologies and techniques to improve user experiences and provide real value to users and businesses alike.

Services: - Development of algorithmic trading systems for a wide range of assets including equities, futures, options, crypto and forex - Automation, backtesting and quantitative research - Evaluation, optimization and consulting to improve investment strategies such as avoiding backtest overfitting and other common pitfalls - Creation of customized indicators, factors, signal services and market scanners including automated notifications - Development and enhancement of framework modules such as execution algorithms (including TCA) and portfolio optimization models - Increasing the efficiency of trading algorithms so that large amounts of streaming data can be processed faster and less hardware resources are required Technologies & Tools: - Python including a wide range of libraries like pandas, numpy, numba, scikit-learn, matplotlib, seaborn and many more - QuantConnect / LEAN - Git and GitHub for version control and collaboration - Supported brokers for live and paper trading: Interactive Brokers (IB), Tradier, Binance etc. Bio: Quantitative trader and mathematician with strong affinity to financial markets and coding. Extensive experience in design, development and analysis of algorithmic trading strategies. I have been trading various financial instruments (equities, futures, options and currencies) for more than 10 years, whereas my approach has become more and more systematic over the years. I graduated with a Master's degree in Mathematics at University of Technology Dortmund (Germany) in 2016. My master thesis is about Schroedinger asymptotic of wave equations in periodic media. The subject belongs to the field of nonlinear partial differential equations and has applications in signal transmission using fiber optics technology. I then worked as an IT Consultant for 3+ years and was mainly employed as a data warehouse engineer and ETL developer in the regulatory reporting department of large financial institutions. I currently work full-time as a professional Quant Developer and have already invested many thousands of hours in R&D of financial markets and systematic trading strategies, building a deep knowledge of quantitative finance and algorithmic trading. Other remarks: My algorithms are always professionally designed and well documented, making them easy to follow. I mostly use the framework approach, so that the code is modular, pluggable and clearly structured, which also makes it much easier to perform adjustments or extensions. I am willing to sign a NDA, if desired, so that the intellectual property (IP) rights remain with you.
