Big Data Jobs
Big Data is the ever-growing amount of structured and unstructured data sets that organizations capture and analyze in order to gain insight, make decisions, and achieve their long-term strategic objectives. A Big Data Developer is arguably one of the most important roles in an organization's data team. These developers have the necessary skills and knowledge to draw insights from large or complex datasets, scale and optimize large datasets manipulations, to automate some of a client's processes, build algorithms for data processing tasks, maintain large databases, work with distributed computing tools for big data initiatives, synch with cloud services and on-site infrastructures and many more. In summation, a Big Data Developer can be critical to helping the organization use the collected data in a meaningful way.
Here’s some projects that our expert Big Data Developer made real:
- Utilized complex algorithms such as KMeans/BisectionKMeans to find anomalies in large datasets.
- Built custom infrastructure solutions that employ massive databases leveraging distributed computing.
- Developed pipelines and dashboards to better visualize data using Tableau/Hadoop/Pyspark/SQL.
- Implemented solutions for continuous logging tasks with Python, managing streaming data inputs into the thousands per second.
- Structured AI techniques with deep learning to detect objects (road edges) from aerial images.
- Optimization measures to reduce storage space requirements, like replacing JSON/CSV formats with Parquet format.
- Applied predictive analytics to forecast outcomes such as credit card defaults and design strategies for database/data warehouse capabilities.
What all these projects have in common is the utilization of Big Data technologies and approaches to develop solutions towards our client's goals. By harnessing the power of Big Data technologies and deploying best practices in data science processes, we help our clients identify opportunities and unlock latent insights in many different ways; this translates into innovative solutions and opportunities that were otherwise unavailable before!

Over the past years, I have devoted myself to a project involving Algorithmic Trading. My system leverages only pricing and volume data at market closing. It studies technical indicators for every stock in the S&P 500 from its IPO date, testing all possible indicator 'settings', as I prefer to call them. This process uncovers microscopic signals that suggest beneficial buying at market close and selling at the next day's close. Any signal with a p-value below 0.01 is added to my portfolio. Following this, the system removes correlated signals to prevent duplication. A Bayesian ranking of signals is calculated, and correlated signals with a lower rank are eliminated. The result is a daily optimized portfolio of buy/sell signals. This system, primarily built with numpy...
