I build AI agents, SaaS products, backend systems, and cloud platforms that are designed for production from day one, not prototypes that need to be rewritten six months later. Today, anyone can generate code with AI. Very few engineers can design systems that continue to perform when real users, payments, integrations, concurrency, and operational complexity enter the picture. That's where I work best. What I'm best at • AI-powered SaaS platforms and multi-tenant applications • Production AI systems, AI agents, RAG pipelines, and workflow automation • High-performance backend infrastructure and distributed systems • Payment, subscription, and Stripe integrations • Real-time applications, dashboards, and event-driven architectures • API development, third-party integrations, and microservices • Enterprise platforms with RBAC, workflows, and business automation For founders and teams who need senior technical ownership without a full-time hire, I also work as a fractional CTO — architecture decisions, technical roadmap, and hands-on delivery from one person instead of a hand-off between a consultant and a dev team. Technologies I use Node.js, TypeScript, Python, PHP, Laravel, React, Next.js, FastAPI, PostgreSQL, MySQL, Redis, MongoDB, AWS, Docker, Kubernetes, OpenAI, Claude, LangChain, LangGraph, and modern cloud-native architectures. Clients typically bring me in when they need to: • Build AI agents with tool calling, RAG, memory, and multi-step workflow orchestration • Turn vibe-coded applications into production-ready systems • Refactor AI-generated MVPs into scalable, maintainable, production-grade platforms • Build a SaaS product from the ground up • Integrate AI into an existing platform • Rescue or scale a backend that's becoming difficult to maintain • Improve performance, reliability, and cloud architecture • Own complex technical problems from architecture through production deployment I care about building software that remains maintainable, scalable, and reliable long after launch. Clean architecture, performance, observability, cost efficiency, and long-term stability are built into every project, not added later. If you're building a serious AI product, SaaS platform, or business-critical application and need an engineer who can take ownership from architecture to production, I'd be happy to discuss your project.

I build AI agents that don't just answer questions ? they take action. In the age of AI, the most valuable automation is an agent that can browse the web, read documents, make decisions, and execute tasks autonomously. I specialise in building these systems for businesses that want to go beyond basic chatbots. What I build: ✅Autonomous AI Agents using LangChain, AutoGen, and CrewAI frameworks ✅Custom AI chatbots with memory, context, and tool-use capabilities ✅AI agents integrated into web apps (React + Flask/Django backend) ✅Voice AI agents using ElevenLabs + Whisper API ✅Lead qualification bots that enrich, score, and route prospects automatically ✅AI customer support agents with escalation logic and CRM integration ✅Multi-agent orchestration systems for complex business workflows My full-stack background means the agent I build for you is production-ready-not a Jupyter notebook prototype. It runs in your app, talks to your database, and integrates with your existing tools. Your business, running on autopilot. Let's build your first AI agent. 💌Describe your process-I'll show you how an AI agent can handle it.

Medical Doctor | AI for Healthcare | Medical AI | Technical Documentation I am a Medical Doctor with clinical experience in Family Medicine and Emergency Medicine, specializing in the intersection of healthcare, artificial intelligence, and medical technology. My work bridges the gap between clinicians, engineers, and healthcare organizations. I help teams build, evaluate, document, and improve medical software and AI-enabled healthcare solutions while ensuring clinical accuracy, regulatory awareness, and practical usability. My background in medicine allows me to recognize clinical nuances that are often overlooked in purely technical projects. Combined with my training in Artificial Intelligence, I contribute to projects that require both medical expertise and technical understanding. My areas of expertise include: • Medical AI and clinical decision-support systems • Medical image annotation and quantitative image analysis (Fiji/ImageJ, histology, immunohistochemistry) • Medical transcription and Natural Language Processing (NLP) • Technical and regulatory documentation for medical devices and healthcare software • Clinical research, scientific writing, and evidence-based medical content Some of the projects I have worked on include: * Technical documentation for the Genesis Hand prosthetic system * User manuals for a Picture Archiving and Communication System (PACS), including AI-related functionality * Documentation for robotic systems and other healthcare technologies * Medical AI projects involving radiology-focused large language model applications * Scientific and technical writing for healthcare organizations, medical technology companies, and academic teams Whether you need a physician to review an AI application, annotate medical datasets, write regulatory or technical documentation, validate clinical workflows, or translate complex medical concepts into clear documentation, I bring both clinical insight and technical precision to every project. I value clear communication, reliable delivery, and documentation that developers, clinicians, researchers, and regulatory teams can all understand.
