Cover image for SoulSync is a concept project

SoulSync is a concept project exploring memory-based compatibility systems. It works by taking ChatGPT memories or conversation summaries and transforming them into structured, evolving traits. Instead of static profiles, it uses a layered memory model: • past conversational context as input • inferred traits (values, communication style, motivation) • weighted updates as new memory is added Think of it as applying ChatGPT-style memory mechanics to human alignment. Built as a systems and coding exercise to explore memory, state, and human-centric modeling

Picture a workflow that captures information, remembers it, and then sends you insights automatically. Your input is stored in memory, so over time the workflow builds a growing knowledge base. Whenever you want, the workflow can retrieve all stored memories and create a concise summary, distilling the key points without you having to dig through everything. Once the summary is ready, it’s sent directly to your email, giving you a digest of relevant information delivered automatically.

In Numun.io (http://Numun.io), workflows are first designed and validated in Agent Studio as structured, multi-step graphs—made up of agents, tools, conditionals, loops, and outputs. Once a workflow is complete, it doesn’t live in isolation. By toggling the workflow on in Agent+ Mode, users can execute that same workflow directly from the AI chat interface. Instead of receiving a simple text response, the AI runs the full workflow behind the scenes and returns structured run results, including tool outputs, decisions taken, and final outcomes. The result is an AI experience that goes beyond conversation, turning chat into a live interface for executing and inspecting real autonomous workflows. In this example, Python code is generated and executed via Fly.io (http://Fly.io), returning a structured summary of results.

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 🧑‍🎄
