Most backend systems work fine until real users arrive , then APIs slow down, automation breaks under load, and AI integrations that worked in testing fail in production. That's the gap I close.
I build backend systems, AI automation pipelines, and cloud infrastructure designed for real-world conditions from day one not patched together after the first failure.
Where I typically get involved:
AI automation systems replacing manual workflows — n8n, Make com, LangChain, and agent-based pipelines built for production scale
Backend architecture using Node.js and Python — API design, scalable systems, and microservices that handle real traffic
AI integration into existing products — OpenAI, LLM workflows, AI agents connected cleanly to backend systems
DevOps and cloud infrastructure — AWS, Terraform, Docker, CI/CD pipelines built for reliability
Data pipelines and web scraping — extraction, processing, and automation at scale using Python and Node.js
Full stack delivery when needed — MEAN/MERN stack with clean frontend-backend architecture
How I work:
Architecture first, no quick fixes. Every system I build is designed to scale, stay maintainable, and not create technical debt that costs more to fix than it would have to build correctly. I've maintained long-term client relationships because the first version doesn't need to be rebuilt six months later.
Tech Stack:
Node.js | Python | Django | MEAN Stack | MERN Stack
n8n | Make com | LangChain | AI Agents | OpenAI API
AWS | Terraform | Docker | CI/CD | DevOps
PostgreSQL | MySQL | MongoDB | REST APIs | API Integration
Data Scraping | Web Crawling | Scalable Data Pipelines
LLM Prompt Engineering | AI Implementation | Automated Workflows
If you're building something backend or AI-driven and need it to work reliably at scale, let's talk.

I'm a UK-based healthcare professional combining clinical expertise with strong written communication and a sharp eye for accuracy. I hold a Master's in Public Health from the University of Salford and a Bachelor's in Pharmacy, with hands-on experience across hospital pharmacy and NHS mental health settings — most recently at Pennine Care NHS Foundation Trust in Greater Manchester.
My combined background in clinical practice, pharmacology, and public health gives me something rare on freelance platforms: the ability to produce healthcare content that is genuinely medically accurate, written in plain English, and grounded in real-world clinical context — not just keyword-optimised filler.
𝗛𝗲𝗮𝗹𝘁𝗵𝗰𝗮𝗿𝗲 𝗖𝗼𝗻𝘁𝗲𝗻𝘁 𝗪𝗿𝗶𝘁𝗶𝗻𝗴
• Patient education articles on medications, mental health, chronic conditions, and preventative care
• UK-focused health blog posts and clinical content for clinics, telehealth services, and healthcare brands
• Pharmacy and medication FAQs, dosage guides, side-effect explanations, and patient information leaflets
• Care home, elderly care, and family-facing healthcare content (dementia awareness, end-of-life communication, daily living support)
• Mental health content with sensitivity and clinical awareness
• Plain English NHS-aware writing that reads naturally to a UK audience
𝗔𝗜 𝗗𝗮𝘁𝗮 & 𝗖𝗼𝗻𝘁𝗲𝗻𝘁 𝗤𝘂𝗮𝗹𝗶𝘁𝘆 𝗪𝗼𝗿𝗸
• LLM evaluation and response rating, particularly in clinical, medical, and pharmacy contexts
• Medical content review, fact-checking, and validation against current guidelines
• Healthcare-related data annotation and quality assurance for AI training datasets
• Search Quality Rating and structured evaluation work
• Strict adherence to detailed guidelines, ethical standards, and confidentiality requirements
𝗪𝗵𝘆 𝗖𝗹𝗶𝗲𝗻𝘁𝘀 𝗖𝗵𝗼𝗼𝘀𝗲 𝗠𝗲
• Genuine clinical credentials — not a general writer guessing at medical content
• UK-based and NHS-trained — content sounds naturally British, with appropriate NHS context
• Native English speaker with strong written communication
• Familiar with handling sensitive health information confidentially and responsibly
• Reliable turnaround, clear communication, and willingness to revise until the work is right
• Combine clinical accuracy with accessible writing — content patients and families can actually understand
𝗛𝗼𝘄 𝗜 𝗪𝗼𝗿𝗸
I treat every project as a collaboration. I'll clarify your brief upfront — target audience, tone, word count, required references, and any compliance needs — so the first draft lands close to what you want. I'm comfortable working independently on long-term content engagements or slotting into existing project frameworks for one-off tasks.
I deliver work that's been read, edited, and proofread before it reaches you. If revisions are needed, I'll handle them quickly and without fuss.
𝗔𝘃𝗮𝗶𝗹𝗮𝗯𝗶𝗹𝗶𝘁𝘆
I'm available to start immediately and open to both short-term tasks and ongoing contracts. I respond promptly to messages and respect deadlines.
If you're looking for a healthcare writer or AI content specialist who actually understands clinical material, I'd be glad to discuss your project.

Bridging the gap between rigorous Quality Assurance and cutting-edge Machine Learning, I am a technical specialist focused on the end-to-end lifecycle of intelligent systems. My expertise lies in architecting automated testing frameworks for AI-driven applications, specifically focusing on Large Language Models (LLMs), Voice AI, and real-time Computer Vision systems. With a background rooted in QA Engineering and a deep pivot into AI development, I ensure that complex, non-deterministic models meet production-grade standards for reliability, accuracy, and performance.
Core Competencies
1. AI & Machine Learning Integration
I specialize in the deployment and validation of advanced neural networks. My technical stack is centered on Computer Vision, particularly the YOLO (You Only Look Once) ecosystem, including versions v8, v11, and the latest v26. I have successfully moved multiple CNN models from local development to production environments using Hugging Face and Gradio, ensuring that the underlying inference logic is both sound and scalable.
2. Intelligent Automation & LLM Testing
Testing LLMs and AI Bots requires a departure from traditional "pass/fail" logic. I implement evaluative frameworks that test for:
Model Hallucination & Factuality: Validating LLM outputs against ground-truth data.
Latency & Throughput: Optimizing real-time object detection and voice response times to ensure seamless user experiences.
Edge Case Robustness: Using deliberate repetition and "overlearning" methodologies to identify failure points in bounding box logic, tracking IDs, and classification confidence scores.
3. Advanced Technical Stack
Programming & Frameworks: Expert-level proficiency in Python, OpenCV, and PyTorch.
Infrastructure: Extensive experience in building and optimizing local AI workstations (utilizing high-VRAM NVIDIA hardware) for training custom datasets, reducing reliance on cloud-cost volatility.
QA Automation: Designing robust CI/CD pipelines that integrate automated test suites with ML training workflows.
Strategic Approach
My methodology is defined by a commitment to technical mastery through depth. I don't just test software; I dissect the architecture behind it. Whether it is a vehicle-and-people counter or a security-focused weapon detection system, my approach involves a rigorous "bottom-up" validation process—ensuring the raw data input, the neural layers, and the final UI output are perfectly aligned.
I thrive in high-intensity, focused environments where the goal is to solve "impossible" technical hurdles. By combining the precision of a Manual/Automated QA Specialist with the innovative mindset of an ML Developer, I deliver AI solutions that are not only functional but resilient.
Key Project Highlights
Medical Imaging AI: Developed and validated classification models for lung pathology and pneumonia with high-precision confusion matrix results.
Real-Time Detection: Engineered tracking systems using YOLOv11 for complex environment monitoring, focusing on ID persistence and spatial accuracy.
Production Deployment: Streamlined the pipeline for deploying custom-trained models to public-facing platforms, ensuring high availability and optimized inference.

Tlanslator/AI Translation Reviewer with 15+ Years of Editorial Experience | Japanese Language Specialist
With over 15 years of experience as a professional writer and editor in the Japanese publishing industry, I bring a sharp editorial eye and deep language sensitivity to AI-generated translation review. I specialise in refining machine-translated Japanese content into text that reads naturally, accurately, and with cultural nuance—ensuring the final output resonates with native speakers.
My work spans lifestyle, parenting, and travel journalism, but what truly sets me apart is my ability to elevate content beyond correctness. I don’t just fix awkward phrasing—I bring clarity, tone consistency, and human warmth to every sentence. Whether reviewing AI outputs or polishing bilingual content, I treat each assignment with the same precision and empathy that have guided my writing career.
Notable highlights include:
• Leading the editorial production of HAPPY MINIMALIST LIFE (SHUFUNOTOMO CO., LTD., 2025), a feature book built on real voices and intentional living
• Regular contributions to ESSE Online, developing lifestyle content from pitch to final layout
• Strong background in adapting content for diverse audiences with speed, structure, and reader-focused tone
I am especially well-suited to projects requiring Japanese fluency, editorial judgment, and the ability to spot nuance in AI translation that non-native speakers might miss. Based in Japan and preparing for relocation to New Zealand, I am eager to support clients seeking high-quality Japanese content review with a human touch.
Let’s work together to make your AI-assisted content truly shine.
