ML Engineer — Computer Vision, Claude/LLM Agents & Audio AI I build deep learning systems across vision, language, and audio — and ship them to production, not just notebooks. I've trained models from scratch, fine-tuned transformer architectures, and deployed to Core ML on real client engagements (including a 400+ hour model-build contract). 5.0 stars across every reviewed project. Computer Vision Image classification, detection, and feature extraction with CNN and transformer (ViT/AST-family) architectures. My core audio work runs on spectrogram based vision models, so the same deep-learning toolkit — convolutions, attention, transfer learning — carries directly into image and video tasks. Claude / LLM Agents & Automation AI agents, automation workflows, and reasoning assistants built on Claude and OpenAI APIs. RAG pipelines, tool-use/agentic systems, and LLM integrations that connect models to real data and real actions. Audio & Speech AI Instrument/audio classification, feature extraction, and transformer fine-tuning (AST, Wav2Vec2, HuBERT), plus generative audio with AudioCraft/MusicGen. Built multiple audio models end to end — clients describe me as central to their ML work. Deployment & Engineering TensorFlow/PyTorch → Core ML export, FastAPI inference services, and optimized real-time / batch pipelines. I handle the messy export and optimization steps end to end. Top Rated · 100% Job Success · 5.0 across all reviewed jobs. I move fast and build things that actually deploy.

"Your business decisions are only as good as the data behind them. Are you mapping your future, or just guessing?" Let’s be honest: In today’s market, location data geocoding and reverse geocoding is often the most underutilized asset in a company's toolkit. Whether you’re a Real Estate developer, a Commercial Farmer, or managing Logistics, ignoring spatial intelligence isn't just a missed opportunity. It’s a financial risk. I don't just "make maps." I build Spatial Intelligence Systems. With over 5 years of hands-on experience and a 100% Job Success Score, I help clients turn massive, messy datasets into clean, automated, and interactive dashboards that actually make sense for their bottom line. From calculating 21 sq km of glacier recession to building real-time crop phenology monitors for rice production, I’ve seen how the right spatial data can save millions. ✅ How I can help your business grow: Risk Mitigation (Real Estate & Insurance): I don’t just show you a map; I analyze flood zones, terrain stability, and site suitability. I help you see the "red flags" before you commit capital. Precision Agriculture (Ag-Tech): I automate the boring stuff. Using Google Earth Engine (GEE), I build pipelines for NDVI and multispectral analysis so you can monitor crop health and yield without manual checking. Operational Efficiency (Logistics & Utilities): I optimize routes and manage assets (like FTTH or Power Plants) with sub-meter precision, cutting down fuel waste and operational lag. Interactive Insights: I transform decades of satellite archives into GEE Dashboards that your team can actually use to monitor changes in real-time. 🛡️ My Tech Arsenal (What I use to get results): Cloud Power: Google Earth Engine (GEE) for large-scale time-series and LULC analysis. Automation: Python (ArcPy, GeoPandas, Rasterio) My goal is always to turn a week’s worth of manual work into a 10-minute automated script. Desktop GIS: ArcGIS Pro & QGIS (Expert level). Specialized Sensing: LiDAR point cloud classification and RADAR (SAR) for flood and terrain monitoring. Industries I’ve Empowered: Real Estate | Precision Agriculture | NGOs & Sustainability | Urban Planning | Logistics & Safari Tourism | Mining & Energy. I’ve delivered $12,000+ worth of complex projects by focusing on one thing: Accuracy. If your data isn't precise, it’s useless. "If you haven't audited your spatial data yet, you're likely operating in the dark. Let’s have a quick chat and turn your location data into your biggest competitive advantage."

I am a Senior AI/ML Engineer with 6+ years of production experience building intelligent systems for clients across the USA, UK, Middle East, and Europe, 50+ projects delivered, 50+ clients served, 100% Job Success on every Upwork engagement. I operate as a hands-on AI technology partner through the full development lifecycle, from initial problem scoping and data engineering to model training, system integration, cloud deployment, and long-term maintenance. My work spans startups, funded ventures, and government institutions, including a production deployment under the United Nations Development Programme (UNDP) for the Government of Balochistan. I specialise in building AI systems that survive real-world conditions, not controlled experiments. This includes fine-tuning LLMs on custom datasets, designing multi-agent pipelines with LangGraph and CrewAI, building RAG architectures with Query Expansion and Cross-Encoder Re-ranking, and deploying computer vision systems on edge hardware. I have also engineered 10+ full-stack software products that are live and actively used by real clients today. My engineering philosophy: the last 20%, deployment, latency optimisation, and production hardening, is where most AI projects fail. That is exactly where I focus. ⦿ Industries and Domains Served Government and Public Sector, FinTech and Accounting, Real Estate and PropTech, Crypto and Web3, Career Intelligence and HR Tech, Transportation and Smart Cities, Healthcare, Research and Academia ⦿ Systems and Solutions Delivered AI Agents and Multi-Agent Systems, RAG Pipelines, LLM Fine-Tuning (SFT, LoRA, QLoRA), Custom Transformer Training from Scratch, Computer Vision Systems, NLP Pipelines, AI SaaS Platforms, Facial Recognition, Sign Language Detection, AI Voice Assistants, Crypto Intelligence Agents, Financial Forecasting, Data Dashboards, Data Engineering ⦿ Selected Work Mind of Pepe — Crypto AI Agent Fine-tuned LLaMA on real trading agent data to build a persona-driven crypto Twitter agent achieving 98% signal accuracy.
