RailRadar is a real-time train detection and arrival prediction system built for communities impacted by rail crossings. Using a distributed network of camera-based tripwire sensors, RailRadar detects train movements at the edge and generates bias-corrected ETAs that adapt to real-world conditions. The system delivers timely, reliable alerts without relying on railroad-provided data or centralized tracking feeds. RailRadar is designed for resilience and accuracy in the field. The platform supports community alerts, operational monitoring, and future integrations with municipal and transportation systems. This project includes full-stack system design, edge sensing logic, backend services, alerting infrastructure, and deployment workflows focused on real-world reliability, not demos.

AI Builder + Agent Studio is a system for designing, testing, and deploying AI agents and autonomous workflows as structured, production-ready graphs, not fragile prompts. At the core is Agent Studio, where workflows are defined as explicit graphs made up of agents, tools, conditionals, loops, routers, and outputs. The AI Builder sits on top of this system and generates complete workflows automatically. Instead of writing code or wiring nodes manually, users describe the goal—and the AI Builder constructs a valid workflow graph. Every workflow can be tested using a test harness, ensuring agents execute correctly before deployment. This project demonstrates how AI agents can be treated like real software systems—versioned, validated, and orchestrated—instead of one-off prompt chains.

Numun.io (http://Numun.io) is an autonomous agent and workflow execution platform designed to turn intent into action—reliably, securely, and at scale. Numun enables users and teams to design, deploy, and run AI-powered agents and workflows that browse the web, call tools, orchestrate systems, and complete real tasks end to end. At its core is a contract-based execution model that emphasizes determinism, observability, and accountability—bringing production-grade discipline to AI agents. Numun is built for developers, operators, and founders who need agents that actually work in the real world—not demos that break under pressure. This project includes full-stack platform development, execution infrastructure, agent runtime design, workflow orchestration, and system-level reliability engineering.

Using AI Builder in Agent Studio, I designed and generated a multi-step workflow that orchestrates agents, tools, conditionals, loops, and parallel execution in a single graph. The workflow interprets user input, plans tasks, executes actions via integrated tools, and produces structured outputs, fully autonomously. It’s a powerful example of moving from AI-generated plan to real-world actionable execution.

Cover image for 🚨 A bug that looks
🚨 A bug that looks like a frontend problem might actually be your backend. I once spent time checking UI code, only to find the real issue was an API returning the wrong data. When debugging, I always check the full data flow: Frontend → API → Backend → Database Debug the source, not just the symptom. 🔍 Have you ever found a backend bug while fixing a frontend issue?
