🚀 About Me

"From a Commerce graduate to an International Hackathon Winning AI Architect, building self-healing multi-agent ecosystems and autonomous software factories."

  • 💼 Current Focus: Architecting TryNext AI (Autonomous Voice-to-Software engine) & the YES Ai Master Edition (Self-healing Multi-Brain OS).
  • ☁️ Cloud & AI Expertise: Google Cloud Certified Developer | Specializing in LLM Orchestration, Multimodal RAG, Serverless Edge Deployments, and DevSecOps.
  • 🚀 Mission: Bridging the gap between business logic and deep tech—building highly scalable, production-ready AI solutions for the "Next Billion Users."
  • 🧠 Core Strength: Designing fault-tolerant, Autonomous Multi-Agent Swarms (Navigator/Curator/Evaluator) with unbreakable auto-failover circuits.
  • Fun Fact: I engineer massive, enterprise-grade AI systems entirely solo — from the initial architectural blueprint to the final Vercel edge deployment.

CHAYRA AI (Autonomous Crisis Response Swarm)

ChayRa AI Architecture

ChayRa AI is not just a chatbot. It is an autonomous, hyper-local crisis response swarm. We are building the ultimate digital safety net for zero-hour emergencies, turning panicked, multilingual voice commands into coordinated survival intelligence.

✨ Core Architectural Capabilities:

  • 🎙️ Polyglot Voice-to-Action Protocol: Built-in military-grade voice command processing. Victims can speak naturally in extreme stress (100+ Local Languages), and the system autonomously decodes, translates, and triggers the rescue swarm.
  • 🗺️ 25km Tactical Routing (Navigator): Automatically scans a 25km radius via OpenStreetMap to pinpoint verified hospitals, civilian shelters, or military bunkers, generating a secure evacuation route from the user's live location.
  • ⚕️ Live AI Triage (Medical Agent): Instantly analyzes trauma context to generate life-saving first-aid steps and medication suggestions. Features a robust offline fallback lifeline protocol if connectivity drops.
  • 🔌 3-Tier Auto-Failover Circuit Breaker: Robust backend logic ensures that if the primary LLM brain fails or hallucinates, the system seamlessly falls back to a secondary module or a "Trust-User" default state(Gemini 3 Pro ➔ Groq Llama 3 ➔ HF Qwen). False negatives are fatal in emergencies, so ChayRa guarantees uninterrupted execution.
  • 📍 Tactical Pin Drop & Live GPS: Victims can transmit their live location via secure GPS handshakes or utilize the "Drop Pin" feature on a tactical map when GPS is spoofed or compromised.
  • 💾 Partner Integration (MongoDB MCP): The Vault Agent autonomously connects to the MongoDB Model Context Protocol (MCP) to securely log and encrypt emergency victim data (Threat Level, Location, Circuit Status) as a secure backend crisis-registry.
  • 🔍 Live Rumor Verification: A dedicated intel search bar allows victims to instantly fact-check local news and dispel panic-inducing misinformation during the chaos of a crisis.
  • 🛡️ Offline-First Mesh Network (Vault Agent): Generates secure alphanumeric emergency beacons. While this prototype currently simulates the rescue beacon workflow, the architecture is explicitly designed for future offline peer-to-peer communication through Bluetooth mesh and WiFi Direct when traditional cell towers collapse.
  • 💻 Glassmorphism Tactical Console: A premium, dark-themed, military-grade UI with dynamic glow states, real-time latency tracking, and autonomous agent processing indicators.

TRYNEXT AI (Autonomous Voice-to-Software Factory)

TryNext AI Architecture







An Autonomous, Self-Healing Software Factory built for the "Next Billion Users." It completely eliminates the coding barrier by transforming natural voice commands (across 100+ local languages) into production-ready, full-stack Next.js applications natively deployed to the Vercel Edge.

✨ Core Architectural Capabilities:

  • 🗣️ Voice-to-App & Live Mod: Speak your idea to build UI/Logic, and seamlessly modify the live application purely via continuous voice commands with TTS feedback.
  • 🤖 Swarm Intelligence: A 3-tier agentic pipeline (Manager ➔ Coder ➔ Evaluator) that reasons, builds, and runs strict QA loops to eliminate hallucinations.
  • 🛡️ Unbreakable Auto-Failover: Zero-downtime routing across multiple brains (Gemini 3 Pro → Groq Llama 3.3 → HF Qwen 2.5).
  • 💎 AI Doctor (Self-Healing): Continuous system monitoring that autonomously scans, generates, and pushes bug-fix PRs directly to GitHub.
  • 🌐 Live Web Clone Engine: Command the AI to extract UI patterns from live external websites and instantly inject them into your project.
  • 🚀 One-Click Public Launch: Push the generated application from the local sandbox directly to a live Vercel URL in seconds.
