That is the question I want to answer here. This post is just a quick jot of my thoughts, and it is something new I want to try with my writing moving forward. Instead of refining everything to some point of perfection, whatever that even means, this piece will stay raw. It is my honest attempt to define what power really is. https://mehmetmhy.com/posts/perfect_tetris/ Sun, 22 Mar 2026 00:00:00 +0000 https://mehmetmhy.com/posts/perfect_tetris/ Project’s GitHub Repo Play My Version Of Tetris What Is This Tetris is a legendary game and one that I enjoy very much. I really love the game and enjoy playing it. It is a great stress reliever. For a fun weekend project, I decided to build the game as a browser game/app designed for both Desktop and Mobile, using the principles of vibe coding. The mobile side of this version was inspired by Play-Tetris, which has a really nice mobile setup with its swipe-based controls. https://mehmetmhy.com/posts/death_of_cha/ Tue, 02 Dec 2025 00:00:00 +0000 https://mehmetmhy.com/posts/death_of_cha/ modified frame from naruto shippuden When I first started working on Cha back in early January 2024, I built it because I needed it. There was no real good CLI terminal tool that integrated LLMs into the terminal at the time that fit what I was looking for. I tried many tools, with chatblade being the closest option, but none of them really worked for my needs. So one day, I decided to build it myself. https://mehmetmhy.com/posts/wwbc/ Wed, 22 Oct 2025 00:00:00 +0000 https://mehmetmhy.com/posts/wwbc/ GitHub Repo • Archived Site • Reddit Post LinkedIn Post • HackerNews Post After 2+ years and 17k+ unique visitors, we’re open-sourcing Notify Cyber! In early 2023, Dylan Eck and I (Mehmet Yilmaz) built Notify Cyber because we were frustrated wading through fragmented cybersecurity news sources. We built a platform that aggregated news from 7+ sources including Apple security releases, CISA alerts, NIST CVE database, Dark Reading, IT Security Guru, Microsoft Security Response Center (MSRC), Trellix, and The Hacker News. https://mehmetmhy.com/posts/barbell_theory/ Tue, 19 Aug 2025 00:00:00 +0000 https://mehmetmhy.com/posts/barbell_theory/ Introduction Over the past few months, I have been thinking a lot about where software value is moving in the age of AI. In April 2025, Guyren G Howe published a blog called Programming in the Age of Abundance. His argument was that as programming becomes cheaper, we will see software explode across every industry and workflow. He believes abundance means more software everywhere, not less. I had been working on my own framework, which I called the Internal Software Leverage Theory. https://mehmetmhy.com/posts/hcr_lab/ Tue, 12 Aug 2025 00:00:00 +0000 https://mehmetmhy.com/posts/hcr_lab/ This post recounts my robotics journey, starting with discovering my passion for robotics in FRC during high school in 2015 to my time as a research assistant at the Colorado School of Mines’s Human Centered Robotics (HCR) Lab from February 2021 to September 2021. Note that since late 2022, the HCR Lab has moved from Colorado School of Mines to the University of Massachusetts Amherst, along with its site from hcr. https://mehmetmhy.com/posts/guardian-grid/ Wed, 30 Apr 2025 00:00:00 +0000 https://mehmetmhy.com/posts/guardian-grid/ GitHub Repo • LinkedIn Post Demo Video • Hackathon Details About Guardian Grid (SF) is a smart city emergency evacuation tool that helps communities respond quickly and safely during major disasters.

It wasn’t until my sophomore year that I joined, due to an initial focus on soccer. The club primarily participated in the FIRST Robotics Competition (FRC), allowing me to explore mechanical and electrical engineering, as well as programming. Through AngelBotics, I learned to use CAD tools, 3D printers, and other engineering equipment, gaining exposure to STEM concepts generally reserved for college students. https://mehmetmhy.com/posts/docuinsight/ Mon, 27 Jan 2025 00:00:00 +0000 https://mehmetmhy.com/posts/docuinsight/ Events September 15, 2025: DocuInsight has been retired but is now fully open sourced at github.com/eandf/DocuInsight with documentation at eandf.github.io/DocuInsight.

As I was developing TARS, it became clear that one of the largest barriers to practical, reliable AI agents was not just task automation, but establishing the trustworthiness of a AI-generated response. Especially when those outputs could impact real-world decisions that can have massive consequences. https://mehmetmhy.com/posts/tars/ Fri, 23 Aug 2024 00:00:00 +0000 https://mehmetmhy.com/posts/tars/ About TARS is an attempt to automate parts of cybersecurity penetration testing using AI agents. This project was originally the main MVP for a startup I co-founded called Osgil. Now it’s an open-source project designed to help cybersecurity professionals. Check out the repo HERE. Demo Quick demo of TARS in action below. For the full demo presented to investors, please get in touch. Long-Term Vision Provide intelligent defense solutions by building AI-Agent based tools for automating cybersecurity penetration testing. https://mehmetmhy.com/posts/cha/ Tue, 12 Mar 2024 00:00:00 +0000 https://mehmetmhy.com/posts/cha/ Project’s GitHub Repo Events August 23, 2025: Cha is no longer maintained. Its actively developed successor is Ch, a lightweight Go implementation offering the same core functionality. Check out the migration blog to understand how and why the switch to Ch was made. About Cha is a simple CLI chat tool for interfacing with OpenAI’s LLM models. While similar projects exist, I couldn’t find one that fit my needs, so I built this tool. https://mehmetmhy.com/posts/mongodb_to_postgres/ Wed, 06 Mar 2024 00:00:00 +0000 https://mehmetmhy.com/posts/mongodb_to_postgres/ NOTE: This blog post is a merger of my MongoDB to Postgres (2024-03-06) and Sequelize vs. Prisma (2023-05-25). The original blogs have been removed, and this blog has taken their place since both contained essentially the same content/information. The migration started in early March 2023, the switch occurred in mid-November 2023, and all instances of the old MongoDB system were completely shut down in early January 2024. Introduction During my time at eBay, I faced what became the most technically challenging problem of my career: migrating the Storage Management System (STMS) from MongoDB to Postgres. https://mehmetmhy.com/posts/insightred/ Thu, 19 Oct 2023 00:00:00 +0000 https://mehmetmhy.com/posts/insightred/ Project’s GitHub Repo About InsightRed is an LLM-powered Account-Based Marketing (ABM) tool that extracts the latest Reddit comments from Subreddits, sorted by “Hot”, and pinpoints users who exhibit potential interest in your project or product.

I had just finished my undergraduate and was working full time as a software engineer. I really wanted to commit to a side project and at the time, I had enough free time to do so. I really did not know what to work on, until I discovered a website called Devpost on August 2022. https://mehmetmhy.com/posts/thn-discord-bot/ Wed, 25 May 2022 00:00:00 +0000 https://mehmetmhy.com/posts/thn-discord-bot/ Project’s GitHub Repo During college, and even now, me and almost all my friends use Discord as one of our main social messaging platform. At the time, and even now, I want to be up to date about cybersecurity news. So I thought, as a fun project, me and my friend would make a Discord bot that would re-post cybersecurity news from The Hacker News into a Discord server. I presented the idea to my friend and he loved the idea, so we started developing it. https://mehmetmhy.com/posts/ros-move-turtle/ Mon, 01 Mar 2021 00:00:00 +0000 https://mehmetmhy.com/posts/ros-move-turtle/ Project’s GitLab Repo Abstract Move Turtle is a simple ROS python script that moves the turtle in ROS’s TurtleSim to specified coordinates (points). This project started as a class project for CSCI473 at the Colorado School of Mines (CSOM) and later evolved into a project I used to help me learn how close-loop systems can be created, the knowledge from which was used to help me with my work at CSOM’s Human Center Robotics (HCR) Lab. https://mehmetmhy.com/posts/simple-lane-detection/ Sat, 09 Jan 2021 00:00:00 +0000 https://mehmetmhy.com/posts/simple-lane-detection/ Project’s GitHub Repo About Simple lane detection (SLD) is, as the name suggests, is software that does simple lane detection. SLD achieve this by just using classical computer vision methods, consisting of: AOI, Thresholding, Canny line detection, HoughLinesP, & point clustering. Using these methods, the detection of the left and right lane(s) of the driving car in the video (point of view) is achieved. Limitations It really only works best if the video data is clean, there are no objects/cars in the AOI, and the road is in ok condition. https://mehmetmhy.com/posts/moving-pose/ Thu, 31 Dec 2020 00:00:00 +0000 https://mehmetmhy.com/posts/moving-pose/ Project’s GitHub Repo Our final presentation from December 2020 About The Project As our final project for the Fall 2020 Introduction to Machine Learning (CSCI470) course at the Colorado School of Mines, our team, consisting of Andrew Darling, Eric Hayes, and myself (Mehmet), implemented the “Moving Pose” algorithm. The goal was to take a skeletal dataset captured by a depth sensor and classify human actions. We not only implemented the core algorithm but also developed a simple user interface to demonstrate its capabilities. https://mehmetmhy.com/posts/svm-on-skeleton/ Sun, 31 May 2020 00:00:00 +0000 https://mehmetmhy.com/posts/svm-on-skeleton/ Project’s GitHub Repo Details This project was project #3 for Dr. Zhang’s Human Centered Robotics (CSCI473) class at the Colorado School of Mines during the Spring 2020 semester.
