I am an applied PhD (Berkeley EECS) scientist with 10+ year industry experience in solving robotics, signal processing, and embedded system problems. I have over 20 years experience working with electronics and embedded systems. I have built entire robotics systems from the ground up (e.g. a car-carrying AGV) as well as led software component development as part of a larger effort (e.g. developed next-gen Fitbit heart rate algorithm). Achieving a certain product or customer outcome requires a high-level systematic viewpoint- I can help break-down this outcome into achievable and straight-forward sub-goals. From there, whether the solution calls for a data-crunching python script or bare-metal C coding, I can bring whatever tools are needed and use them with mastery. We are now bringing world-class talent together to push technological progress at Think Circuits LLC, where I am CEO. Here are some problems I can solve for you: * New algorithm development- Set requirements, design, implement and validate. * Improving legacy algorithms - Determine weaknesses of an existing algorithm, determine high-value improvements, implement and regression testing to track gains. * Embedded circuits design - Design and fabricate special purpose electronics such as sensor data loggers or controllers. * Research- Pursue a research direction such as applying a research paper to a given problem, report on feasibility What skills are in my "wheelhouse" of tools? * Robotic localization and mapping (SLAM) : Graph-based and filter-based * Classic Estimation and control: Kalman filtering, full-state controllers/estimators, PID control * Signal processing : Frequency and time domain analysis, PCA, adaptive filtering and regression * Classic machine learning : SVM, Random forest, polynomial regression * Regression testing scripts and statistical analysis of performance * Fluent in C,C++, Python * Experience with Javascript, Typescript, Linux * Embedded circuit design What will working with me be like? For development or research work, I will first try to understand the problem you are trying to solve and determine whether it is within my area of expertise. If I am able to help, I will propose some directions or options. If possible, we can identify the interfaces which separate my work from the rest of the project and come up with requirements definitions on those interfaces. Then, I can be fairly self-sufficient to implement the outcome. Other times, the desired outcome is less clear and so a more "agile" approach can be taken with greater back-and-forth between us.

Hi There, My main expertise is in SharePoint and providing fast and tangible automation to daily processes for a variety of companies and enterprises. I have over 10 years experience where I used SharePoint to create full life cycle ticketing systems, procurement management applications, custom billing reference tools and other user focused solutions. I am looking to take on projects of all sizes, and to provide an above and beyond user experience along with the automation capability that day to day users or administrators require. I have experience in managing SharePoint migrations from SharePoint 2010 to 2013 and 2010 to SharePoint Online, where I updated SharePoint designer workflows to Power Automate workflows and converted InfoPath tools to the modern SharePoint online experience. Detailed Knowledge: • Experienced in SharePoint 2007, 2010, 2013 and SharePoint Online with Power BI/Automate/Apps, Visual Basic(VBA), Nintex, InfoPath forms, SharePoint Designer, ShareGate migration tool, JavaScript/HTML web parts, REST API, Azure User Configuration and SQL. • Expert capability in creating custom web parts, Excel macros, Microsoft Visio, VLOOKUPs and PowerBI reports for KPI information. • Business analysis experience and project management of multiple Agile/Waterfall methodology projects at one time. I can provide further examples of my experiences and the tools I have created in the past upon request. Thank you for your time, -Mikhail Krivin
