Saif Ur R.

⭐ Full-Stack AI Engineer | AI, LLMs, Real-Time Systems, E-Learning & Digital Human Interaction ⭐ I have successfully delivered software and AI projects for leading global organizations and enterprises, including  Ciena, Merck, Red Cross, ADT, SaskTel, Queensland Government, Toshiba, IBM and McDonald’s. I specialize in designing and implementing innovative solutions for Digital Human Interaction, intelligent automation, and high-level system architecture. I build intelligent, scalable AI applications—from real-time LLM/NLP ingestion pipelines and low-latency streaming systems to Retrieval-Augmented Generation (RAG), embeddings, multimodal AI, and AI-powered conversational agents. My core backend stack includes Python, FastAPI, WebSockets, PostgreSQL, Redis, and distributed microservices, enabling the development of secure, highly responsive, and production-ready AI systems. I have also expanded my expertise into Solana blockchain dApps, developing production-ready token programs, liquidity-pool (LP) integrations, and on-chain transaction workflows with a focus on reliability, security, and scalability. 🔹 Articulate Storyline, LMS & E-Learning • Development of interactive e-learning courses and digital learning experiences using Articulate Storyline • Creation of interactive simulations, assessments, quizzes, knowledge checks, branching scenarios, and multimedia learning modules • LMS integration and preparation of SCORM/xAPI-compatible learning packages • Integration of narration, video, animations, screen recordings, interactive exercises, and learner interactions • Development of responsive and engaging learning content for corporate training, employee onboarding, product training, and educational programs • Troubleshooting LMS publishing, tracking, completion, scoring, and learner-progress requirements • Custom JavaScript/API integrations where advanced Storyline functionality or external system integration is required 🔹 AI, LLM & NLP • LLM integration with OpenAI, Claude, Hugging Face Transformers, Twilio, and ElevenLabs APIs • Retrieval-Augmented Generation (RAG) using pgvector, Pinecone, semantic search, and semantic chunking • Whisper speech-to-text transcription with speaker diarization and sentiment analysis • Real-time AI systems using FastAPI, Server-Sent Events (SSE), and WebSockets • Conversational AI, AI agents, voice AI, and Digital Human Interaction • Multimodal AI pipelines integrating text, voice, and other data sources • PostgreSQL/Supabase-based data and AI application architectures 🔹 Full-Stack Development • Frontend: React.js, Angular, responsive and production-grade user interfaces • Backend: Python — FastAPI, Flask, Django • Databases: PostgreSQL, Supabase, Redis — optimized schemas, queries, caching, and data layers • APIs & Real-Time: REST APIs, WebSockets, SSE, third-party API integrations • Cloud & DevOps: Docker, CI/CD, AWS (EC2, S3, ECS, Lambda), GCP • Serverless: Python/AWS Lambda for IVR, NLP, data-layer services, infrastructure, security/configuration, observability, and CI/CD I focus on delivering production-ready, secure, scalable, and maintainable solutions tailored to each client's requirements. Beyond development, I provide post-launch support, troubleshooting, optimization, and continuous improvements to help ensure long-term project success. Let’s connect to discuss your project, technical requirements, and how I can contribute to building a reliable and scalable solution. Thank you, Saif
