Top Rated Plus | Top 10 Machine Learning Agency on Upwork | $500K+ Earned | 8+ Years in AI & Software Engineering I'm an AI Engineer building production-grade AI agent and RAG systems, not simple prompt wrappers. With 8+ years in software engineering and AI development and $500K+ earned on Upwork, I hold Top Rated Plus status and our team is ranked among the Top 10 Machine Learning agencies on the platform. I work with companies that need an AI system to actually run in production, handle real user traffic, and stay accurate, not a demo that breaks on the first edge case. As an AI Engineer, my core work covers retrieval-augmented generation pipelines, agentic workflows with tool calling and structured outputs, prompt engineering, and LLM integration with OpenAI, Anthropic, and Gemini APIs. This is the kind of system clients need an AI Engineer for: not a chatbot that answers FAQs, but an agent that retrieves the right information, calls the right tools, and follows through on what the user actually needs, with hallucination reduction and evaluation built in from the start. As a Machine Learning Engineer and Data Scientist, I build systems for structured and time-series data: demand forecasting, anomaly detection, biomedical signal analysis, and structural health monitoring. My data scientist workflow covers Python, scikit-learn, pandas, NumPy, and SciPy alongside deep learning frameworks including TensorFlow, PyTorch, and Keras, with experiment tracking and evaluation metrics to ensure models perform consistently in production. When a project needs predictive or classification models alongside the AI agent itself, I own that layer too as a Machine Learning Engineer. As a Computer Vision Engineer and software engineer, I build object detection, multi-object tracking, pose estimation, and image segmentation systems using OpenCV, YOLO, and deep learning architectures. Where this intersects with the AI Engineer work is in multimodal systems and computer vision agents: I work with Vision Language Models (VLMs) to build AI pipelines that understand images and video, not just text. Most AI Engineers only work with text. I bring production computer vision and deep learning experience on top of the LLM layer, which matters for any product where the AI needs to see, not just read. On the engineering side, I work as a Python developer and software engineer building backend services with FastAPI, vector databases including Pinecone and pgvector, and LangChain or custom orchestration for multi-step agent logic. When a project needs full ownership of both the AI layer and the surrounding application, I work as a Full Stack AI Developer, handling backend APIs, database design, and frontend integration so the AI system ships as a complete product, not just a backend script. I work with a specialized team that includes a computer vision PhD, deep learning researchers, and mathematical optimization specialists. This lets me scope larger systems, split orchestration, retrieval, and evaluation work across the team, and deliver a full AI Engineer and Machine Learning Engineer engagement faster than a solo contributor could, with the software engineering discipline of clean APIs, logging, and testing baked in from day one. Clients typically work with me when they need: - an AI Engineer to build a RAG pipeline, AI agent, or chatbot that actually works in production - a Machine Learning Engineer or Data Scientist to build predictive models or structured data pipelines - a Computer Vision Engineer to add visual understanding or VLM-based reasoning to an AI product - a Software Engineer who understands LLM orchestration, tool calling, vector search, and backend architecture - a Python developer who can own the full stack from model training to deployed API If you need an AI Engineer and a software engineer with the full stack from prompt design to production deployment, let's talk. Main stack: Python, OpenAI API, Anthropic Claude, Gemini, LangChain, LangGraph, LlamaIndex, FastAPI, Pinecone, pgvector, TensorFlow, PyTorch, Keras, OpenCV, YOLO, Docker, PostgreSQL, JavaScript, Git.

I build production-ready LLM systems and agentic AI pipelines that automate complex workflows. Top Rated on Upwork | 20+ projects in multi-agent AI, generative models & data engineering with PyTorch. Clients come to me when they need AI systems that actually ship — not prototypes. Whether it's a multi-agent orchestration layer, a custom RAG pipeline, a diffusion model for audio/image generation, or a data engineering workflow at scale, I handle the full cycle from architecture to deployment. What I work on: → Agentic AI & Multi-Agent Systems (LangChain, LangGraph, Groq, tool-use agents) → LLM Integration & RAG (retrieval pipelines, fine-tuning, prompt engineering) → Generative AI — Audio & Image (diffusion models, voice synthesis, latent space modeling) → ML Model Development (PyTorch, TensorFlow, classification, NLP, CV) → Data Engineering & Pipelines (PySpark, AWS SageMaker, ETL, 100GB+ datasets) Recent work includes a 7-layer multi-agent data processing engine, a latent diffusion model for synthetic medical audio generation (reduced FAD from 18.82 → 14.71), and a natural language chatbot interface for Grafana dashboards. I communicate clearly, deliver on time, and document everything. I don't disappear mid-project and I don't overpromise scope. If something's not feasible, I'll tell you upfront. If you're building something serious in AI — let's talk. Send me a message and I'll usually reply within a few hours.

I build Claude Code automations for business operations that typically pay back the full project cost within 7 days — by replacing 1-3 SaaS subscriptions, eliminating 10-40 hours/week of manual work, or both. Most of my clients are operations leads, founders, and regulated-industry teams who hit a wall with hosted tools (ChatGPT Team, Claude for Work, Microsoft Copilot, Zapier, Make) on data residency, custom integrations, or escalating per-seat costs. I deploy self-hosted Claude Code on their infrastructure — VPS, on-prem servers, or Mac Mini — with full audit trails, zero SaaS dependency, and direct integration into Slack, Gmail, Notion, HubSpot, Salesforce, and custom systems. — RECENT RESULTS — - Replaced 3 SaaS subscriptions ($890/month) with a single Claude Code RAG assistant — paid back in 9 days, ongoing savings $10.6K/year - Cut a client's reporting cycle from 4 days to under 2 hours with a Claude Code analytics pipeline piped into Slack and Notion - Built a 12-agent customer intelligence platform on Claude Code that lifted retention 43% and processes 500K+ customer profiles per hour - Deployed autonomous Claude Code agents for a hedge fund processing 2M+ market signals daily — 34% higher returns, 90% less human oversight - NLP document processing on Claude Code that cut manual review workloads by 50% for legal and operations teams - Credit scoring models that drove default rates below 0.1%, holding through full economic cycles - AI treatment recommendation engine with HIPAA-grade audit logging for a healthtech provider — WHY MOST SELF-HOSTED CLAUDE CODE SETUPS FAIL — Most setups I inherit have the same problems: API keys in plaintext configs, gateways exposed to the public internet, agents running as root, no skill auditing, no human-in-the-loop, no documentation when something breaks at 2 AM. I rebuild that foundation first, then layer automation and integrations on infrastructure that holds up under audit. — WHAT YOU GET — - Self-hosted Claude Code deployment on VPS, on-prem, or Mac Mini - Zero public gateway exposure (Tailscale, WireGuard, Cloudflare Tunnel, mTLS) - Secrets management for Anthropic, OpenAI, Gemini API keys with rotation policies - Non-root Docker containers, read-only workspaces, scoped tool permissions - Compliance-ready posture: HIPAA, GDPR, SOC 2 — RBAC, audit logs, human-in-the-loop on destructive actions - Native integrations: Slack, Teams, Gmail, Outlook, Google Calendar, Drive, Notion, Asana, Salesforce, HubSpot, plus custom systems via API and MCP - Cron-driven daily briefs, weekly reports, multi-source monitoring - Full handover package: user manual for non-technical operators, security checklist, reference architecture diagram — STACK — Claude Code, Anthropic Claude API, Model Context Protocol (MCP), OpenAI API, Google Gemini, Python, TensorFlow, PyTorch, Docker, Kubernetes, Linux, AWS, GCP, Tailscale, WireGuard, Cloudflare Tunnel, REST APIs, webhooks. — HOW TO START — Send a short message with: (1) your current setup, (2) the workflow you want automated, (3) any compliance constraints. I'll reply within 4 hours with a concrete scope, timeline, and the 7-day payback math for your specific case.

There are many freelancers here who can collect, clean, and analyse data. I focus on turning messy data into something you can actually use. For 6+ years, I’ve helped teams deal with messy, scattered data, pulling it from websites, APIs, PDFs and turning it into something they can actually use. Not sure what data you should be collecting or where to get it? Want to scrape data from 10–15+ websites and standardise it into one format? Still doing things manually just to get basic insights? Dealing with pipelines that break every time a website updates? Spending hours cleaning messy data before you can even use it? Have data, but no clear way to turn it into decisions? Missing opportunities because your data isn’t updated in real time? That’s usually where I come in. Most of my work ends up being a mix of fixing broken pipelines, automating manual workflows, and building systems that just run quietly in the background. I’ve built things like: data aggregators pulling from 10–15+ websites automated research and competitor tracking systems pipelines that clean and process large, messy datasets *Some of these have been running for years without much maintenance. I try to keep things practical. No over-engineering. No unnecessary complexity. If something can be simple, I’ll keep it simple. If it needs to scale, I’ll build it properly. *I’ll also tell you honestly if something doesn’t make sense before you spend money on it. If you’re dealing with messy data, broken workflows, or too much manual work, I can help you fix it properly. *If you’re dealing with messy data or broken workflows, send me a message — we’ll fix it.
