Licensed Electrical Engineer | Top Rated | 1000+ Hours on Upwork
I deliver arc flash hazard analysis, protection coordination studies, short circuit calculations, and power system models — using SKM PowerTools, ETAP, EasyPower, and PowerWorld Simulator — formatted for direct client submission worldwide.
You provide SLDs, equipment data, and project scope.
I return fully modeled, analyzed, and documented study packages your reviewing engineer can stand behind.
That is exactly what I do.
I work as your dedicated power system analyst. You provide the data — SLDs, equipment nameplates, utility fault information, and your project scope. I deliver fully modeled, thoroughly analyzed, and professionally documented study reports, ready for review, approval, and submission by your licensed or chartered engineer of record.
I do not provide licensed engineering stamps or country-specific certifications. My role is rigorous technical analysis and documentation that gives your approving authority — whether a PE, CEng, or local regulatory engineer — a complete, defensible package to work from.

I help software teams turn AI ideas into reliable products - from early R&D and technical direction to production delivery.
I work with companies introducing AI into an existing product, moving an LLM prototype into production, or changing engineering processes around AI-assisted development.
My work starts before implementation: clarifying where AI creates real leverage, mapping workflows and constraints, prioritising use cases, and testing the technical direction before a team commits serious budget. I help with AI strategy, R&D, technical due diligence, architecture, build-vs-buy decisions, and AI-enabled SDLC.
I build production AI systems, including LLM applications, RAG platforms, AI agents, self-hosted models, computer vision, and machine learning. The difficult work is rarely choosing a model. It is designing the system around it: company data, context engineering, integrations, evaluation, monitoring, latency, cost control, security, and predictable behaviour.
Core areas:
✅ AI agents and workflows - tool use, MCP integrations, memory/context management, human approval gates
✅ Production engineering - Python, FastAPI, Docker, APIs, AWS/Azure, scalable data infrastructure
✅ RAG and internal knowledge systems - hybrid retrieval, pgvector/Qdrant, reranking, evaluation
✅ AI reliability - observability, evals, regression testing, audit trails, governance
✅ Text-to-Voice(ASR), Voice-to-Text(TTS) and real time voice agents
Recent work includes a RAG troubleshooting system for a UK manufacturer funded by Innovate UK; an AI investment-research platform; LLM compliance automation for AdTech; and an AI-assisted music-therapy product used in dementia and autism care.
I have 10+ years of software engineering experience and stay personally involved from discovery and R&D through architecture and delivery. If you are assessing an AI opportunity or need to make an AI system reliable in production, I can help define the right next step.

3D Design, Modeling, and Printing:
I provide complete 3D design and fabrication services, creating detailed CAD models and producing physical components through FDM and SLA printing. Designs are developed in SOLIDWORKS for accuracy, proper tolerances, and clean integration with electronic assemblies.
Each model is reviewed for printability, strength, and fit before fabrication. I work with materials including PLA, PETG, ABS, and engineering-grade resins, producing high-quality prototypes and functional parts.
