As a Top Rated Plus AI & Machine Learning Engineer (Top 3% on Upwork) with over 6 years of experience and a 100% Job Success Score, I deliver end-to-end enterprise AI implementations. My expertise spans heavy-compute machine learning, embedded IoT ecosystems, real-time voice intelligence, and autonomous agentic workflows. Having built intelligent applications, vision systems, and predictive pipelines for over 50 global clients across Fintech, Healthcare, Robotics, IoT, and SaaS, I prioritize structural risk mitigation, deterministic behavior, and clear data lineage to guarantee real corporate ROI. My practice focuses on engineering production-grade Retrieval-Augmented Generation (RAG) architectures and autonomous multi-agent networks governed by deterministic software frameworks. To ensure high factual precision and secure role-based access control, I replace naive chunking with advanced relational data indexing, multi-stage re-ranking, and custom self-RAG verification loops that systematically eliminate model hallucinations and minimize token overhead. When building multi-agent ecosystems to execute complex, multi-step business logic, I implement clean state transitions, persistent cross-session memory management, and secure tool invocation. This architectural discipline ensures that autonomous units handle real-world operational friction gracefully and self-correct without entering infinite execution loops. This commitment to low-latency orchestration and structural reliability extends directly to my real-time conversational Voice AI deployments. I build human-grade voice agents for inbound qualification and outbound telephony centered on conversational fluidity. By optimizing the complete text and speech streaming pipelines, I achieve response times under 600ms while establishing strict barge-in rules and turn-taking logic that accommodates natural human pauses. I anchor these Generative AI systems with deep foundational roots in traditional statistical machine learning, deep learning, and physical edge compute. Whether training custom neural networks or engineering real-time computer vision architectures for digital and edge devices - including past infrastructure deployments for rapid-growth tech startups - my code enforces mathematical and computational efficiency. I ensure hardware streams, embedded sensors, and unstructured data lakes feed cleanly into automated ETL pipelines, yielding actionable analytics and enterprise business intelligence dashboards. ============================================================================= TECH STACK & KEYWORD MATRIX: [ Agentic & RAG Orchestration ]: LangGraph, CrewAI, AutoGen, LlamaIndex, Semantic Kernel, Custom FSM Runtimes, Multi-Agent Architecture, Self-Correction Loops, Model Context Protocol (MCP) [ Enterprise Voice AI & Telephony ]: Vapi, Retell AI, ElevenLabs, Cartesia, Deepgram, AssemblyAI, Twilio API, SIP Trunks, WebRTC Audio Streaming, Turn-Taking Logic, Conversational Voice Agents [ LLMs, SLMs & NLP Ecosystem ]: GPT-4o, Claude 3.5 Sonnet, LLaMA 3, DeepSeek, Mistral, OpenAI API, Hugging Face, Natural Language Processing (NLP), Advanced Prompt Engineering, Model Routing Layers, Small Language Models (SLMs) [ Machine Learning & Computer Vision ]: TensorFlow, Keras, PyTorch, Scikit-Learn, OpenCV, Deep Learning, Image Processing, Spatial Intelligence, Object Detection, Semantic Segmentation, Data Science [ Edge Computing & Hardware Integration ]: Embedded Systems, Robotics, Embedded IoT, Real-Time Sensing, Physical Computing Architecture [ Cloud Infrastructure, MLOps & Data Engineering ]: AWS (Lambda, SageMaker, EC2, S3), Serverless Architectures, Microservices, N8N, Make, Automated API Integrations, SQL, Vector Databases (Qdrant, Pinecone, Milvus, pgvector), Neo4j Graph Databases, Advanced Data Analytics, BI Dashboards, Business Intelligence ============================================================================= FULL-STACK INTEGRATION & APPLICATION LAYER: I provide end-to-end full-stack integration to ensure intelligence is delivered seamlessly.

Most AI projects don't fail because of bad code — they fail because nobody checked if the results can actually be trusted. I build and validate intelligent systems: agentic pipelines, LLM-powered workflows, and the evaluation frameworks that make them safe to act on. My work sits at the intersection most engineers avoid: where technical results meet real-world accountability. Recently, my focus has expanded into agentic AI engineering and AI security — designing multi-agent systems with built-in quality loops, hallucination detection, bias auditing, and compliance filters. I don't just build pipelines; I build pipelines that check themselves. I've worked across computer vision, NLP, OCR pipelines, and clinical/academic research — including cell classification, ASR data, and publication-ready statistical analysis. Where I add the most value: — You need an agentic system that produces outputs you can actually trust and act on — You have a model or dataset and need to know if it's reliable before it goes anywhere near a decision — You're writing a thesis, paper, or clinical report and need analysis that survives peer review — Your stakeholders need to understand what the AI actually found — and what it didn't — You need an honest assessment of where your AI system could fail, be gamed, or cause harm I'll tell you honestly if ML isn't the right solution for your problem. That's rarer than it sounds.

✅ $300K+ Earned | Top Rated Plus | 8,000+ Hours | 38 Jobs | 100% Job Success I build production-grade LLM, RAG, and AI Agent systems. Not prototypes. Not API wrappers. Real Python pipelines, deployed on AWS, handling real traffic. If your AI needs to actually work in production, let's talk. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🤖 LLM AND GENERATIVE AI ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ End-to-end LLM applications using OpenAI (GPT-4o), Claude, Gemini, LLaMA, and Mistral. Full RAG pipelines over your documents, databases, and knowledge bases. AI Agents and multi-agent workflows built on LangChain, LangGraph, and LlamaIndex. LLM fine-tuning with LoRA, QLoRA, PEFT, RLHF, and DPO on open-source models. Prompt engineering, tool calling, memory patterns, guardrails, tracing, and LLM evaluation harnesses. If your team is moving an LLM prototype to production, this is exactly where I work. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚡ FASTAPI AND DJANGO BACKENDS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FastAPI and Django are my backend stack of choice for AI-powered services. → Async REST APIs: FastAPI + Pydantic + SQLAlchemy + PostgreSQL → Scalable Django backends: DRF, Celery, Redis, multi-tenant SaaS architecture → FastAPI as the serving layer for LangChain, RAG, and agent endpoints → Auth systems: JWT, OAuth2, RBAC → Microservices, Docker, Kubernetes, CI/CD via GitHub Actions and GitLab CI → Swagger / OpenAPI documentation, clean architecture, full test coverage ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎙️ VOICE, AUDIO, VIDEO AND TEXT AI ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ → Voice AI agents and real-time speech pipelines (Whisper, AssemblyAI, Deepgram, ElevenLabs, VAPI, Retell AI) → STT / TTS integration, NLP, NER, and multimodal LLM pipelines → Computer Vision: YOLO, OpenCV, CNNs, Vision Transformers → Diffusion pipelines and image / video generation workflows → Audio transcription, classification, and processing at scale ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🧠 ML, MLOPS AND VECTOR SEARCH ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ML Stack: PyTorch, TensorFlow, HuggingFace, scikit-learn, XGBoost Vector DBs: Pinecone, Weaviate, Milvus, FAISS, pgvector, Elasticsearch Serving: vLLM, TGI-style inference, batching, caching, routing, streaming responses MLOps: MLflow, DVC, Prefect, Ray, eval harnesses, regression testing, tracing Cloud: AWS (SageMaker, EKS, EC2, Lambda, Bedrock, DynamoDB, CloudFront), Terraform, GPU providers ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🏆 WHAT MAKES ME DIFFERENT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Most AI freelancers deliver a Jupyter notebook or a thin wrapper around an API. I architect and ship the full system. I have 14+ years of engineering experience and a background as a Fractional CTO and AI/ML Team Lead. I have led teams and personally written the code. I think in systems, delivery, and cost control, not just individual features. At Alethea AI, I was part of the team that built a cloud-native architecture on AWS capable of accommodating 30 million visitors, highlighted in an official AWS case study. The platform publicly closed a $16M token sale. That is the level of production reliability I bring to every engagement. ✔ Architecture designed for scale from day one ✔ Clean code, full documentation, and production observability ✔ I write the code myself, no offshoring your project ✔ Reliable delivery: timelines, milestones, and accountability ✔ Cost-controlled cloud and GPU workloads ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🤝 WHO I WORK WITH ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Startups validating AI-first MVPs fast. Scaleups moving LLM prototypes to production. Product teams that need a senior AI/ML engineer who can own the full stack, from fine-tuned model to FastAPI endpoint to deployed AWS service. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📩 Message me with your current state, timeline, and constraints. If I can help, I will tell you exactly how, usually within a few hours.
