In my next episode of “build something lightweight that I need but can’t find anywhere” comes this care coordination app. I built it to simplify my own post-surgery recovery. As an introvert, coordinating with multiple people and scheduling is a pain. This quick app made it easy to coordinate meals, errands, and pet care with family and friends without the added stress. V1 was mostly hard coded (Next JS/html). V2 is built with: Next.js, React, Node.js, Prisma, and Postgres DB. Deployed on Vercel for rapid iteration.

I built and studied a multi-robot coordination system in Webots to understand how different navigation strategies affect team performance in exploration tasks. Using Clearpath PR2 robots, I implemented and compared Route, Survey, and Mixed human-inspired strategies, along with obstacle avoidance and conflict resolution in C++. By running controlled simulations, I measured how strategy choice impacts task completion time, coverage, and coordination efficiency. One key result was that mixed strategies consistently produced more robust and efficient teams, offering insights directly relevant to real-world search, rescue, and exploration robotics.

Multi-Robot Coordination & Simulation in ROS2 Designed and implemented a ROS2-based multi-robot simulation platform to study coordination, navigation strategies, and communication-aware exploration. Integrated SLAM Toolbox, Nav2, map merging, and multi-agent coordination logic. Used Python and C++ nodes with live visualization in RViz to evaluate efficiency, coverage, and cooperation under different strategies.🚀

Alter Ego is a personalized AI assistant I built and deployed on my website using OpenAI’s ChatGPT. It’s designed to represent how I think and work, not just answer questions. The system uses a structured persona, curated knowledge from my research and projects, and context-aware prompting to hold accurate, grounded conversations about my background in AI, robotics, and agentic systems. The goal is not imitation for novelty, but continuity: enabling clear, truthful interaction with my work, ideas, and problem-solving approach even when I’m not present. Please check out the demo on my website: https://amirmohaddesi.github.io/

DocForge AI is a document automation system that uses Large Language Models as reasoning engines, not just text generators. Instead of simply “writing” documents, the system analyzes structure, constraints, and intent to produce professional, publish-ready outputs such as resumes, SOC 2 reports, technical specifications, and compliance documents. LLMs are orchestrated to plan sections, enforce schemas, validate consistency, and adapt tone and layout to industry standards. The result is documents that are not only well-written, but correct, coherent, and visually polished, reducing manual effort while maintaining trust and professional quality.

In my previous role at a startup, I was the sole Android Engineer responsible for the native mobile apps. I had the opportunity to create a new Android app. It was an app that allowed warehouse workers to scan barcodes on packages to create an electronic chain of custody. The client who requested this app was happy with the results. I exceeded expectations by delivering the app ahead of schedule (2 weeks vs. 1 month). The necessary features were in place, and the app was user-friendly. https://play.google.com/store/apps/details?id=ai.beans.isp.scan

Cover image for I recently watched a video

I recently watched a video of someone going on a trip to see the Northern Lights. At the end of the video, the person showed a timelapse of the Northern Lights, and I was in awe. Given the holiday season, I was curious to see what a Christmas tree under the Northern Lights would look like. I was able to find the following image (https://media.istockphoto.com/id/2224224036/photo/aurora-borealis-northern-lights-over-christmas-tree-strong-aurora-storm-yellowknife-northwest.jpg?s=612x612&w=0&k=20&c=1folij9hCKe3GGvXlHLu171g2uR_zUl52KZmNsGufPI=). I used this image as inspiration to create a festive EDM song on Suno: https://suno.com/s/y8UK3O8PNWftC0E9 With these themes in mind, I had Lovart generate a holiday card (second image in post). From me to you, Merry Christmas & Happy Holidays Hope you enjoy the song 🧑‍🎄
