Executor

Executor is an autonomous meeting-to-execution enforcement system built for enterprise teams that lose accountability after meetings. Most AI meeting tools stop at summaries, but Executor continues into execution by extracting commitments, identifying owners, deadlines, priorities, and source quotes, then turning those decisions into tracked work. Users can upload transcripts or run live meetings with Speechmatics real-time transcription. Gemini analyzes the meeting, extracts structured action items, scores execution risk, and powers follow-up drafting. Each commitment can be synced directly into Jira, Asana, and Notion, connecting meeting decisions to the tools teams already use. Executor also runs a background enforcement agent deployed on Vultr. The monitor checks deadlines every six hours, marks overdue commitments, drafts follow-up emails, retries failed sends, and escalates to managers after repeated missed follow-ups. Human review remains available before sensitive messages are sent, while every autonomous action is stored in an audit log. The application is deployed publicly on Cloudflare Workers, uses Supabase for authentication and database storage, Gemini for reasoning, Speechmatics for voice transcription, and Vultr for the scheduled enforcement worker. Executor closes the gap between “we decided” and “it actually got done.”

AI Virtual Puppet Theater

AI Virtual Puppet Theater is an immersive AI powered browser experience that transforms users into live digital puppeteers through real time gesture control, facial tracking, and cinematic storytelling. The project combines computer vision, realtime animation, and interactive stage design to create a magical virtual theater where users control expressive 3D characters using natural human movements. Using webcam based hand tracking and facial detection, players can perform combat, emotional reactions, celebration animations, and cinematic interactions. The system tracks gestures, blinking, eye movement, facial expressions, and head motion to make puppet characters feel emotionally alive and deeply connected to the user. Characters react dynamically with expressive eyes, animated emotions, smooth movement interpolation, and theatrical body language. The platform includes a complete cinematic story mode featuring dramatic sequences between a King, Lion, Hero, and mysterious dark creature, brought to life through curtain transitions, realtime lighting, particle systems, and synchronized animation, all running directly inside the browser. The technical stack includes Next.js, TypeScript, Tailwind CSS, React Three Fiber, Three.js, Zustand, MediaPipe, TensorFlow.js, face-api.js, and Framer Motion, with strong focus on low latency interaction and immersive presentation quality.

AI WAFS web application firewall

What Would Blow Our Minds ● A guardrail system that stops prompt injection without blocking legitimate use ● AI that reasons about adversarial intent like a security expert ● Something that adapts to new attack patterns automatically ● Multi-layered defence that validates inputs, outputs, and behaviour ● A system that makes AI agents safe to deploy on the public internet ● Defence that explains WHY something was blocked in human-understandable terms Why This Matters Now AI agents are being deployed in production with access to sensitive data and critical actions: ● Prompt injection is the SQL injection of the AI era ● AI agents can take real-world actions - making attacks more dangerous ● Traditional security tools weren't designed for natural language inputs ● New attack techniques emerge faster than manual defences can adapt ● Organisations need guardrails before widespread AI deployment creates security incidents AI can be used to detect and defend against AI-specific attacks using adversarial reasoning andintent analysis.

Vibe Studio: AI-Native Agentic IDE

Vibe Studio represents a paradigm shift in how developers interact with Artificial Intelligence. Most current solutions are merely basic chat wrappers grafted onto existing code editors, lacking true integration with the development lifecycle. Vibe Studio, however, is built from the ground up as an AI-native Integrated Development Environment featuring a custom Agentic UI. At its core, Vibe Studio replaces the standard "prompt-and-pray" approach with a deterministic, event-driven architecture. We implemented an asynchronous Pub/Sub execution bus and a rigorous state machine (RoadmapTracker) that orchestrates complex, multi-step LLM workflows. This means the AI doesn't just spit out code snippets; it follows a structured lifecycle—from architectural analysis to implementation, and verification. Our platform is designed for senior engineers who demand control. The human architect sets the constraints, defines the patterns, and dictates the workflow, while the autonomous agents handle the mechanical execution. Features include real-time intent-guard pipelines to prevent prompt contamination and strict architectural enforcement. Vibe Studio isn't just another coding assistant; it is a robust, production-grade infrastructure designed to scale developer output without sacrificing engineering fundamentals.

CodeGuardian.AI

CodeGuardian.AI is a unified developer platform designed to simplify software maintenance, improve security, and accelerate the entire development lifecycle. Instead of relying on multiple disconnected tools for testing, vulnerability scanning, modernization, and architecture analysis, CodeGuardian.AI brings everything together into a single AI-driven workspace powered by IBM Bob MCP integrations. The platform intelligently analyzes repositories to identify outdated coding patterns, risky dependencies, hidden edge cases, and structural bottlenecks. It can automatically generate modernization suggestions, create advanced edge-case test suites, detect security vulnerabilities mapped to CWE standards, and explain findings in plain English for developers of all skill levels. Interactive architecture visualizations also help teams understand large codebases faster and onboard new contributors more efficiently. Built with a modern TypeScript-based stack using Next.js, Express, TailwindCSS, and React Flow, the project focuses heavily on usability, scalability, and production-quality engineering. CodeGuardian AI aims to become a future-ready AI engineering assistant that helps teams ship secure, reliable, and maintainable software with greater confidence and significantly reduced debugging and QA effort.
