Most AI Agents look great in a demo, then break the moment real customers hit them. I build AI Agents, Voice AI systems, and RAG pipelines engineered to survive production, not just a sales call. Give me a workflow to automate and I'll turn it into an AI Agent that runs 24/7 that's the promise. Top Rated AI/ML Developer on Upwork | 5+ years building AI Agent, Voice AI, RAG, and LLM Automation systems | $20K+ earned | Python, JavaScript, PostgreSQL 𝐖𝐇𝐀𝐓 𝐈 𝐁𝐔𝐈𝐋𝐃 **AI Agent Development** I architect AI Agents with tool calling, memory, and multi-step reasoning using LangChain, OpenAI SDK, and custom LLM orchestration. Every AI Agent I ship is Agentic AI in the true sense it connects into CRMs and business tools (HubSpot, GoHighLevel, Calendly) and completes the task end to end, not a chatbot wearing an AI Agent label. **Voice AI & Voice AI Agents** I build inbound and outbound Voice AI Agents for lead qualification, appointment booking, and call automation. Built Chatley.ai, a 24/7 AI voice call automation platform with VAPI integration, multi-language support, and Stripe billing. Built Voxr.ai, an outbound Voice AI Agent using ElevenLabs for voice synthesis, Deepgram for transcription, and Twilio for telephony. On Upwork, currently tuning an outbound lead-qualifying Voice AI Agent, and previously shipped a Twilio + OpenAI Voice AI receptionist for a plumbing company recovering missed after-hours calls. **RAG & LLM Systems** I build production RAG pipelines connected to vector databases Qdrant, OpenAI vector stores so AI Agents answer from real business data instead of hallucinating. Built IDEO Lab, a multimodal RAG workspace: a node-based AI Agent canvas that ingests documents, websites, YouTube, and social media, then runs RAG-grounded chat with LLM-powered responses across OpenAI (chat, vision, Whisper) and LangChain, plus Claude for structured extraction and reasoning tasks. **AI Automation** I connect AI Agents and RAG systems into the automation layer businesses already run on — n8n, Make, Zapier, GoHighLevel. Recent AI Automation work: system hardening for Verbai (Phase 4), and an AI-powered MVP using LLM + RAG + computer vision (PDF/OCR parsing) for construction shop-drawing document analysis — turning unstructured documents into structured data science pipelines. Also built: RolePlay.ai, an AI Agent-driven roleplay training platform using LangChain and Voice AI for sales/customer-service simulation and real-time scoring.

Businesses that need a RAG-powered AI Agent grounded in their own documents and data science. Teams that need AI Agent Development and Machine Learning to replace manual, repetitive workflows. Send me your use case. I will tell you honestly whether an AI Agent, Voice AI system, or RAG pipeline is the right fix and I will build the AI Agent that actually ships.

I'm a Top Rated freelancer and Computer Science graduate who works at the intersection of three fields most people treat separately: Statistics & Machine Learning, Bioinformatics, and AI. That combination is exactly what messy, high-dimensional data needs — the statistical rigor to trust the result, the ML to find the pattern, and the biological context to know what it means. With 3+ years of experience and 24 successful projects (4.98/5 avg. rating), here's what I bring: 📊 Statistics & Machine Learning Rigorous statistical inference and predictive modeling — hypothesis testing, causal inference (Mendelian Randomization), feature engineering, and ensemble models (XGBoost, LightGBM, Random Forest). I don't just build models that score well; I build models you can defend. Example: a coronary artery disease prediction model reaching 0.956 AUC, with feature ablation to prove what actually drives it. 🧬 Bioinformatics & Omics End-to-end analysis of complex biological data — scRNA-seq, RNA-seq, WGS/WES — using reproducible pipelines (Nextflow, Snakemake). From raw reads to normalized matrices to differential expression and biomarker discovery. Example: cut analysis time by 40% on large genomic projects through custom automated pipelines. 🤖 AI & Deep Learning Deep learning frameworks for real diagnostic problems — computer vision, medical image analysis, NLP, and LLM-based tools. ✨ What ties it together Most freelancers do one of these. I connect them — applying AI and ML to biological and clinical data with statistical discipline, then communicating the findings in publication-ready visuals that both scientists and stakeholders can act on. 🛠️ Tech Stack Python (Pandas, Scikit-learn, TensorFlow, PyTorch) · R (Tidyverse, Bioconductor) · Bash · SQL · Linux · Git · Docker · Cloud 💡 Ready to turn your raw data into discoveries you can trust? Let's talk.

Most teams don't need more AI ideas. They need AI that actually works in production, integrated into their existing tools, automated end-to-end, and built to survive real data and real users. I'm Ali Dabouei (PhD), a full-stack AI engineer based in Vienna, VA. I own the entire delivery: model design, pipeline architecture, backend/frontend development, API integrations, automation workflows, and cloud or on-prem deployment. One person, full accountability, prototype to production. What I build: Agentic AI · RAG pipelines · Voice AI agents · Computer vision · OCR & Document AI · Generative AI · AI automation & API integrations Recent work: • Logistics OCR platform: 10,000+ invoices/week at 98%+ accuracy, with automated auditing and billing discrepancy detection • Agentic legal framework: native legal CRM integration automating 60%+ of routine legal tasks, no Zapier or n8n • Voice AI agents: deployed across healthcare scheduling, B2B sales qualification, real estate lead follow-up, and 24/7 restaurant order handling, all with full CRM, calendar, and operations dashboard integration. • RAG assistants: on-prem document analysis, e-commerce support across chat/email/social, and adaptive tutoring • Sports video analytics: YOLO + SAM pipeline extracting player tracking and tactical metrics from raw game footage Tech stack: Python · FastAPI · LangGraph/LangChain · React · Next.js · PostgreSQL · AWS · Twilio · ElevenLabs · Deepgram · Pinecone · Weaviate · PaddleOCR · PyTorch · OpenCV · YOLO · Amazon Bedrock · Google Gemini · REST APIs My background is research-heavy (PhD WVU, postdoc CMU, 30+ publications) but my style is practical: fast prototype → tight feedback loop → rigorous stress-testing before launch. I build automations natively, integrate directly with your APIs and CRMs, and have on-prem deployment experience for security-sensitive environments (legal, healthcare, finance). Typically, I start with a short discovery call or scoped paid milestone to validate the approach before committing to a full build.
