    Focusing on Database Administration, Network & System Administration, Programming, and Networking with a flare for integration using various technologies. MS SQL Query Tuning/Optimization, jQuery, JavaScript, AWS EC2 Instances, PowerShell scripts, Cold Fusion, and minimal Google Cloud. I am a well-rounded senior-level IT consultant with very diverse skills & experiences in many industries and countries. I have a get-it-done attitude, and I look for creative ways to achieve a solution that means fewer headaches for the client. My experience starts from the days when DOS was all we had. This knowledge means I know what is really behind the window versus those that only see the window itself; the façade. Many people know how to drag and drop a button onto a form in the studio, but can they write the code to make it work on the backend without a WYSIWYG interface? I usually can. I once challenged a .Net programmer to create code, and I would write classic ASP with C# (on the backend), and it was faster to code and just as efficient and scalable. Back in the dBase days, I wrote an Indexing routine that was faster than the one built-in to the software. These days I prefer to have SQL Server on the backend. Excel, Access VBA are no problem. The 3 J's: JavaScript, jQuery, JSON are also no problem. I prefer to do remote consultations since I travel all over the world.

    I am a professional cloud architect, data engineer, and software developer with 18 years of solid work experience. I deliver solutions using a variety of technologies, selected based on the best fit for the task. I have experience aiding startups, offering consulting services to small and medium-sized businesses, as well as experience working on large enterprise initiatives. I am an Amazon Web Services (AWS) Certified Solutions Architect. I have expertise in data engineering and data warehouse architecture as well. I am well versed in cloud-native ETL schemes/scenarios from various source systems (SQL, NoSQL, files, streams, and web scraping). I use Infrastructure as Code tools (IaC) and am well versed in writing continuous integration/delivery (CICD) processes. Equally important are my communication skills and ability to interface with business executives, end users, and technical personnel. I strive to deliver elegant, performant solutions that provide value to my stakeholders in a "sane," supportable way. I have bachelor's degrees in Information Systems and Economics as well as a Master of Science degree in Information Management. I recently helped a client architect, develop, and grow a cloud-based advertising attribution system into a multi-million $ profit center for their company. The engagement lasted two years, in which I designed the platform from inception, conceived/deployed new capabilities, led client onboardings, and a team to run the product. The project started from loosely defined requirements, and I transformed it into a critical component of my client's business.

This has vastly improved our data quality."

    At UC Berkeley, I helped submit several Computer Vision and Reinforcement Learning papers. Here is a short list for context: - GANs for Model-Based Reinforcement Learning - Frame Rate Upscaling with Constitutional Networks - Neural Multi-Style Transfer At Amazon, I built a pipeline framework to store and serve sales data for the millions of third party merchants on Amazon.com. More recently, I have taken on part-time consulting. These are some of the clients and projects I have worked on in the past: - GitHub on Improving Code Classification with SVMs - SAP on Applying HANA Vora to Load Forecasting - Intuit on Quantifying Brand Exposure From Unstructured Text As opposed to these previous projects, I am looking to take on more projects, each with smaller time commitments.

    Tableau developer and dashboard designer with five years of development experience. Specialize in KPI selection, Tableau dashboard development, Data visualization and data transformation with SQL. Tenured analyst with over ten years of experience in the marketing analytics landscape. Extensive experience across B2B, B2C, SAAS and eCommerce business models, focused on improving revenue metrics without relying on increased marketing spend. Thrive in fast-paced, quick turnaround engagements. If you have raw data that needs to be transformed or engineered into a dataset for visualizing, dashboarding or general reporting purposes - I can't wait to help you solve your challenges. I have extensive experience while working with leading technology providers like Atlassian in providing data engineering support to transform your data from jumbled data sets into a cohesive series of tables and business logic, to then be visualized for you. Core skills include: Marketing Analytics | Visualizations | Executive Dashboards Segmentation | KPI Selection | Product Analytics Technical skills include: SQL | Tableau | ETL | Google Analytics | Data Studio | Looker And accolades I have received from prior stakeholders: - I've worked with Tyler for nearly four years and there is so much I could say about him. Even in the very beginning, Tyler was handed nearly impossible problems to solve. It seems like the harder the problem the more invested he is in solving it though. Never satisfied with being comfortable and always onto the next adventure, Tyler is an analytics powerhouse that I'm lucky to have on the team. In addition to his work ethic, his personality and ability to play as a team makes him such an important factor in team moral. He's always helping others, making people laugh, and down to hang out after work for a beer or two. I've enjoyed every minute of working with him! (Jessica Vetorino, Atlassian) - I and Tyler worked together as part of the Stride/Hipchat team. Tyler was part of the extended marketing team and was responsible for the marketing analytics function. He did a kick-ass job of reporting daily/weekly/monthly on the health of the business and actively looking for insights into the data. The last part is most important - you elevate yourself as an analyst when you don't wait for questions to be asked but you formulate them yourselves. He not only excelled analytically but was also very pleasant to work with. You want to be surrounded by team players like Tyler. I will hire him again in a heartbeat. (Raj Sarkar, Atlassian)
