    ๐Ÿฅ‡ Top Rated Plus Contractor since 2020 ๐Ÿฅ‡ 10+ years of professional experience ๐Ÿฅ‡ 98% Client Satisfaction Rate ๐Ÿฅ‡ 350+ real stores built on Shopify in the last years ๐Ÿฅ‡ 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.

    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.

    I'm guessing you're here because you want something amazing built, but you're either stuck or you aren't sure where to go next. Perhaps you have customers relying on you or you have the latest cool idea. Whatever it is, I'm here to help. PASSIONATE | DEPENDABLE | HONEST I prefer working with folks on long-term engagements, though I'm always willing to help out on one-off projects. Skill set: Full stack web, automation, testing, Python, Node.js, Mongo, Falsk, REST, and many more... Work history: over a decade of tech experience; over 7 of full stack; 4-5 years as a freelancer. What to expect if you work with me: 1. Initial call. I'll ask plenty of questions, listen for what you're looking for, offer guidance and suggestions for anything I think won't work. I'll estimate how long the project will take and bring up any potential roadblocks i see. 2. Development. I'll work on the project, communicating throughout the project. If anything comes up unexpectedly I'll tell you about it. 3. Delivery. This is where I will provide the final project to you for approval. I'm open to modifying anything within the scope of the work if it doesn't match up with expectations. I'm very relational when I work with folks. Everyone is unique and I don't expect each client to get a one-size-fits all. --- A note on the recent 1-star review: I always aim for excellence. With the client it was a fairly simple job that I was more than capable of handling. The job was to fix something on a server. I'm very careful about working something if there's the potential for catastrophe, and checked with everyone to ensure if I worked on this part of the server it wouldn't affect production. However, it was not the case, and production was affected (essentially the IDE I opened it in "updated" some of the settings, breaking a lot of things). I owned my mistake and offered to work with the team to get production back online, but they weren't interested. My mistake was working on their server; instead, I should have set up my own development environment to troubleshoot the issue.

    Hi! Upwork uses my first name, Royce, but I go by Aaron (my middle name). I am a quantitative /systematic trader that also helps others with all things related to running algorithmic trading systems. This includes tasks such as system modeling/backtesting, data collection/storing, signal processing based on technical indicators, portfolio and position risk management, etc. I am a skilled programmer that writes well documented and organized code that is easy to follow and build upon. I provide even more value with my trading knowledge and experience. I've contributed to hundreds of successful projects to date, and look forward to taking on many more. Some of my specialties includes using QuantConnect (where I am a recommended consultant), Interactive Brokers API integration, TradeStation, and TradingView. I've learned a lot about technical analysis going through the Chartered Market Technician (CMT) program where I've passed the first 2 of 3 exams on my first try. My past and current clients include investment/financial advisors, portfolio managers, CTAs, and professional traders. I also work with individuals that are just getting started in trading. Check out the testimonal below to see what an active client who manages around 150M+ AUM had to say about working with me. If you are interested in learning how to write algorithms for QuantConnect, I've created a training course of 22 different algorithms that I explain in 27 videos, almost 17.5 hours of instruction. Message me if you are interested, and I can send you more information.

    First and foremost, I know my hourly rate is high, but being an extremely quick problem solver, I will spend fewer hours finishing your project compared to an average freelancer, while making sure that quality is at the highest level. Please DON'T consider hiring me if: - you are looking for a beginner/mediocre developer that will do the job for you as cheaply as possible - you don't want to discuss and answer questions, share a wider context about your project. I want to provide my services as I was your business partner. - my work doesn't create more value for you than your investment in my work.

    Residing in Frankfurt, Germany, I am a seasoned AI/ML Leader, bringing over 15 years of industry experience to the table. My expertise spans both Generative and Predictive AI, with a deep-seated understanding of technologies such as OpenAI's APIs, LlaMa, Open Source LLMs, Hugging Face, Vector Databases, and LangChain, among others. In the sphere of Generative AI, I've successfully integrated OpenAI's Large Language Models (LLMs) and various other open-source LLMs with diverse internal enterprise repositories such as Salesforce, SQL Database, and Vector Database. This has empowered these systems with capabilities akin to ChatGPT, thereby enhancing the utility of internal data. The applications of this integration span across Customer Support, Enterprise Search, and Analytics, among others. Turning to Predictive AI, I've harnessed the power of Deep Neural Networks for intricate pattern recognition and predictive analytics. Additionally, I've employed Time Series Forecasting for trend identification and future projections, among a myriad of other AI use cases. Having gained extensive experience across the Retail, Pharma, and Manufacturing sectors, I've consistently delivered strategic and technical solutions that are data-driven. These solutions have catalyzed industry-specific transformations and growth, underlining my ability to leverage data science for tangible business outcomes.
