What I Built
- Architected a production-grade AI multi-model orchestration platform with three distinct phases: Phase 1 (AI Chat) integrating 20+ latest models including OpenAI (GPT-5.5, GPT-5.4, GPT-5.2, GPT-5.1), Google (Gemini 3, Gemini 3 Pro, Gemini 3.1 Pro, Gemma 3), Anthropic (Claude Opus 4.7, Opus 4.6, Opus 4.5, Opus 4.1, Sonnet 4.5, Sonnet 4), xAI (Grok 4.2), Meta (LLaMA 4 Maverick), Mistral (Mistral 3), DeepSeek (DeepSeek 3.2), Qwen (Qwen3), MiniMax (MiniMax M2), Nvidia (Nemotron Nano), and Moonshot (Kimi K2.6, Kimi K2.5, Kimi K2.2), with intelligent model routing, token streaming, and context window optimization achieving sub-300ms first-token latency.
- Engineered Phase 2 (Best vs Best Comparison Mode) enabling parallel execution of 2-4 models simultaneously (with capability to handle up to 8) for the same query, supporting GPT-5.5, GPT-5.2, Gemini 3 Pro, Gemini 3.1 Pro, Claude Opus 4.7, Claude Opus 4.6, Grok 4.2, LLaMA 4 Maverick, Mistral 3, DeepSeek 3.2, Kimi K2.6, Kimi K2.5 and 20+ Latest LLMs with side-by-side response rendering, latency benchmarking, and quality scoring – allowing users to visually compare outputs and select the best result, processing 10M+ tokens distributed during testing with efficient resource utilization across parallel executions.
- Built Phase 3 (Voice-to-Voice Mode) supporting GPT-5.5, Claude Opus 4.7, Claude Opus 4.6, Kimi K2.6, and 20+ Latest LLMs with real-time speech recognition (Azure Speech), voice activity detection, and streaming text-to-speech with natural prosody, achieving <300ms end-to-end voice latency and enabling conversational AI for visually impaired users and hands-free interaction with 7+ language support.
- Implemented a unified RAG pipeline with ChromaDB on Azure VMs (Central India) storing 10M+ embeddings, providing semantic context retrieval with 0.25 similarity threshold and topic-aware filtering to deliver hallucination-resistant responses across all three phases, achieving 95% reduction in hallucinations.
- Designed an MCP-compliant prompt engineering layer with dynamic system/user role injection, adaptive tone control (professional, casual, friendly, technical), and long-term memory using Redis for session persistence, enabling context-aware conversations that remember user preferences and conversation history.
- Created a fine-tuning orchestration engine that allows per-model prompt customization and response formatting (JSON, markdown, plain text), ensuring consistent output structure across different models and enabling seamless switching between phases with zero configuration changes.
- Developed a comprehensive security layer with JWT authentication, Google/GitHub OAuth, rate limiting (3 requests/minute per user), API key validation, and IP-based blocking to prevent unauthorized access and abuse, processing 50K+ daily API calls with zero security breaches and 99% reduction in API abuse.
- Built a real-time token streaming architecture using Server-Sent Events (SSE) and WebSockets, delivering incremental responses with <50ms chunk intervals, and implemented context streaming for long conversations, reducing perceived latency by 60% and improving user engagement.
- Integrated Azure Communication Services for real-time chat and video consultations between users and AI mentors, supporting 1000+ concurrent sessions with <50ms latency, and added Azure Speech Services for voice-to-voice interaction with 7+ language support including English, Hindi, Spanish, French, German, Japanese, and Mandarin.
- Optimized multi-cloud infrastructure using AWS CloudFront CDN for static assets, Azure Load Balancers for compute, and strategic Redis caching, achieving sub-100ms API responses for 90% of requests and reducing infrastructure costs by 25% through intelligent auto-scaling and dynamic model routing based on cost/latency optimization.
