I build production web, mobile and desktop applications end to end — and I ship fast, because AI tooling is part of how I work, not something I bolt on afterward. What I've shipped in the last two years: • A multi-clinic European healthcare platform — I own the Billing, Messaging and Accounting modules end to end, architecture through production. Multi-tenant with role-based access control, audit logging and full GDPR compliance, serving hundreds of clinicians daily. • A React Native app live on both the App Store and Google Play. I built nearly the entire application: authentication, offline state, push notifications, CI/CD and post-launch monitoring. • Integrations with three national government health systems — the first product to activate all three simultaneously, with official recognition from each. • react-auto-i18ner — my own published npm package. A CLI that turns a multi-day React internationalization migration into a single command. • Full product builds for US and UK clients — NestJS APIs, React Native apps, Next.js admin dashboards, data pipelines processing gigabytes of records. What I work with: Web — Next.js, React, TypeScript Mobile — React Native, Expo, EAS build and store submission Backend — Node.js, NestJS, Express, Fastify, Python, FastAPI Databases — PostgreSQL, Supabase, MongoDB, Firebase, Redis Desktop — Electron.js AI — OpenAI API, LangChain, CrewAI, RAG pipelines, AI agents, Hugging Face, Ollama for local models Infrastructure — AWS, Docker, GitHub Actions, CI/CD How I work: I take ownership. Tell me the outcome you want and I'll handle the architecture, the build, the deployment and the parts nobody thought to scope. You'll get plain-language updates without having to chase me for them. I'm a good fit if you need: • A SaaS platform or web app built properly from scratch • A mobile app taken from idea to live on both stores • AI features — agents, chatbots, RAG, automation — added to a product you already have • One developer who owns the whole stack, instead of coordinating three specialists Tell me what you're building and what "done" looks like. If I'm not the right person for it, I'll say so.

I build SaaS products and AI automation agents end-to-end. Django backend, Next.js frontend, LLM pipelines. 15+ apps shipped for founders who needed it done right the first time. Most founders learn this the hard way — after hiring someone who built a prototype that couldn't handle real users or real data. I'm the developer you hire to avoid that problem. I'm Numan — a full-stack developer specializing in Django/Python backends, React/Next.js frontends, and AI automation systems. 3+ years, 15+ production SaaS products shipped across fintech, AI tooling, health tech, geospatial systems, and e-commerce. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HERE'S WHAT I'VE ACTUALLY BUILT: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ Hectar Labs — commodity trading platform processing 97,546+ shipments across 189+ ports. Built the full trade lifecycle API, automated P&L engine, and AI market intelligence. Reduced trade creation time from 30 min → 5 min. ▸ Mappex — real-time geospatial collaboration system. Built the web platform AND the React Native mobile app. ▸ Foxing Fit — AI workout script generator with coach-defined rules, not generic prompts. ▸ Hural.pro — AI resume SaaS with per-job tailoring. CyberVisionaries — AI video prospecting tool for B2B sales. ▸ Plus: classified marketplaces, fintech dashboards, and 8+ multi-tenant SaaS products. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT I BRING: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✔ Full ownership — backend, API, frontend, AI agents, and deployment. No handoffs between specialists. ✔ I've already solved the hard SaaS problems — auth, billing, multi-tenancy, real-time sync, AI pipelines, and LLM workflow automation. You're not paying for my learning curve. ✔ I build AI agents that actually work in production — not chatbot wrappers. Multi-step reasoning, tool use, document pipelines, automated decision workflows. ✔ I ask why before I ask how. ✔ Professional English. Available for calls. Deadline-driven. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ MY STACK: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Backend → Python, Django, DRF, PostgreSQL, Redis, Celery Frontend → React.js, Next.js, TypeScript, Tailwind CSS Mobile → React Native (iOS + Android) AI/LLM → OpenAI, Anthropic Claude, Gemini, Hugging Face, LangChain Infra → AWS, GCP, Docker, Nginx, CI/CD ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ BEST FIT FOR: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ → SaaS platforms that need to be built right, not rebuilt later → AI agents and LLM workflow automation → Fintech, trading, or data-heavy applications → Full-stack projects where one person owns the whole thing If your project fits — send me a brief description. I'll tell you honestly if I'm the right fit and what building it would realistically take.

Hi, I am Robert Marian Iurea, an AI and Full-Stack Engineer based in Cluj-Napoca, Romania. I help startups, scale-ups, and product teams turn ambitious AI ideas into real, revenue-generating applications. Over the past several years, I have designed, developed, and launched production-ready systems across healthcare, cloud education, event technology, marketplaces, and media. I manage the full development lifecycle, including system architecture, back-end services, front-end development, automation, cloud deployment, monitoring, and monetization. Clients work with me when they need one engineer who can take a project from an empty repository to real users without passing the work between multiple specialists. My main strength is integrating modern AI models into scalable and user-friendly platforms. I work directly with large language models such as Google Gemini and Hugging Face Transformers, computer vision tools including YOLOv8, OpenCV, TensorFlow, and TensorFlow.js, and speech recognition models such as Distil-Whisper. I always consider privacy, speed, cost, reliability, and the product’s path to monetization. One of my latest projects is DermaVision, a skin lesion analysis platform for smartphone and dermoscopic images. I created a unified dataset of 53,813 images from nine dermatology sources, built the annotation and data-processing workflows, trained segmentation and classification models, and developed the PTN++ image-processing pipeline. I also integrated the models into a browser-based application and tested an ensemble with my previous MoleScan model. Other results include a video accent analyser that runs 1.46 times faster than the standard Whisper baseline and identifies nine accents with 85 to 90% accuracy, and an AI wedding optimisation suite that reduced manual planning time by more than 90%. I also build LLM-powered content curation and social media automation pipelines using n8n, Gemini, Node.js, and Telegram bots, helping marketing teams reduce repetitive work. On the full-stack side, I work with Python, TypeScript, and JavaScript across Next.js, React Native, Expo, Node.js, Express, Streamlit, and Progressive Web Apps. I build APIs and data layers using PostgreSQL, Prisma, Firestore, Convex, and MySQL. I also integrate services that real products need from day one, including Stripe, Google Play Billing, Clerk authentication, Firebase, Sentry, Resend, UploadThing, Spotify, LinkedIn, and Telegram Bot APIs. Cloud and DevOps are part of my delivery process. I have experience with Google Cloud Platform, Docker, CI/CD pipelines, DigitalOcean, Firebase, and Streamlit Cloud. I hold the following Google certifications: Google Professional Cloud Architect Google Cloud Digital Leader Google TensorFlow Developer Certificate I also completed the Generation UK Google Cloud Engineer trainee programme in London. This combination of AI, product development, and cloud experience allows me to build systems that are intelligent, reliable, secure, and ready to scale. Whether you need an AI feature added to an existing product, a new MVP with subscription billing, a mobile app published on Google Play, or an internal automation system that saves your team time, I bring a practical and results-focused approach. I communicate clearly, document important decisions, and work with short feedback cycles so you always know what is being delivered next. If you need an engineer who can take an AI or full-stack product from idea to production, including architecture, development, automation, deployment, and monetization, I would be happy to discuss your project. Send me a short brief with your goals, timeline, budget range, and preferred technologies, and I will respond with a clear plan, realistic milestones, and recommended next steps. I am available for fixed-price MVPs, ongoing retainers, and focused consulting projects.
