ABOUT ME

MY STORY

My name is Matt Kohn and I am a software engineer living in New York City. I graduated from Brown University with a concentration in Computer Science in 2019. I grew up in a village named Moreland Hills near Cleveland, Ohio. I am always trying to learn more about software engineering and urban planning, as well as mathematics, physics, philosophy and a myriad other subjects. In my free time, I enjoy reading, exercising, meeting new people and having discussions.

MY SKILLS

COURSEWORK SKILLS FROM EDUCATION

I have learned a myriad of skills from my coursework at Brown University. In my introduction to computer science, I immediately picked up extensive commenting and testing of all aspects of my projects; from map-reducing to seam carving. When it came to computer systems last fall, I extended my knowledge beyond the typical object-oriented paradigm and began to consider system efficiencies and throughput with projects like rewriting C's dynamic memory allocator and creating a multithreaded database that can handle multiple clients on a server. Another semester, I applied different methods in Python to approach solutions to issues in artifical intelligence.

Projects

Chagrin Falls High School gave me a solid foundation in computer science. I began coding freshman year in Visual Basic, picking up basic syntax and proper indentation. Then in AP Computer Science, I began to learn Java and of its vast intricacies in projects like recreating Dr. Mario and Pacman in Java applets. Then in Honors Advanced Data Structures I expanded my knowledge of the assets available in Java, as well as the decision process for how to pick which data structure is most appropriate, exemplified by projects like utilizing stacks and postfix expressions to create a calculator and setting up a pseudo-email server using queues. And finally senior year I explored algorithms and discrete math in independent studies and began to pick up learning techniques and environments quickly and effectively.

GPA

Through my various interests, summer jobs and independent studies, I have learned an amalgam of different skills and techniques across various side projects and experiences. Over the summer of 2016, I built some Java applets to review the basic structure of large projects, and in doing so created Tetris and a Sudoku board generator and solver. These projects made me familiar with GitHub and the MVC model. I have also released two iOS apps on the App Store, and through such have gained insights into the concerns of user interfaces as well as Swift. Besides side projects, I have participated in a hackathon on Brown's campus, where I acquired my knowledge of Git and version control within the dynamics of a team, as exemplified by our most recent project Nome. Lastly, in high school, I started iGuy, a business where I would aid members of my community with technology issues, and gained a more in-depth understanding of the implications of user design and interfacing.

  • EXPERIENCE

    JANUARY 2023 - PRESENT

    TaxBit

    After TaxBit acquired Tactic in early 2023, I was then a software engineer at TaxBit. Continued supporting existing Tactic accounting solution using React/Typescript frontend, Python Flask backend, Redis cache, PostgreSQL, Airflow task scheduler and AWS-backed architecture (S3, DynamoDB, EC2, RDS). Orchestrated design and implementation of third party vendor integration for a universal Enterprise Resource Program API, leveraged this API to integrate with NetSuite, Xero, and 10+ other accounting systems, widening our clientele base to support larger enterprise domestic and international companies serving millions of crypto transactions. Collaborated across different internal teams to build out a generalized integration system, simplifying the process of adding new datasource integrations and reducing average time to add new integrations from 3+ weeks to less than 1 day. Constructed system that generates key reports to account for FASB accounting guidelines changes, implemented method of reporting to reflect fair market value and impairment adjustments, enabling customers to adhere to standard General Accepted Accounting Principles, something not yet offered in the crypto accounting industry. Initiated a role-based access system paradigm in the application to include read-only users alongside the existing admin users. Migrated tens of frontend API calls into using React Query to cache results and reduce load times for the app from 5 minutes for customers with 100,000+ transactions down to <1 minute.

    Started as the third engineer (fifth employee), helped the startup grow from having no official product and no customers to being robust enough to be valued at around $70M and acquired by the $235M series B company TaxBit (valued at around $1.33B) in a year. Became the in-house accounting expert and primary point of contact for the QuickBooks integration, critical for allowing customers to sync and resync their crypto transaction data, close their books monthly, and utilize manual and automated journaling using Airflow. Executed all workflows around syncing transactions and journaling, implemented individual, batch and compressed bulk syncing and resyncing, as well as designed a robust journaling system capable of processing tens of thousands of complex transactions. Added integrations for Gemini and Coinbase Exchange, enabled customers to connect to their centralized exchange data and pull in at least 200,000+ transactions.
