About me

Full Stack Developer & AI Automation Specialist, 10+ years experience. I build scalable web apps, SaaS platforms, and production-grade AI systems (agents, RAG, voice automation) not demos, real systems that run reliably. I combine solid engineering with AI to solve real business problems.

10+ Years Experience | 250+ Successful Projects | Trusted by Fortune 200 Companies & Funded Startups
Over the past 10+ years, I've built scalable web applications, SaaS platforms, and more recently production-grade AI systems, carrying each one from architecture through to deployment.
My work sits at the intersection of two specialties: solid full-stack engineering, and modern AI agent, RAG, and voice automation. Most clients today don't need one or the other they need a real product with AI woven into it from the start, not bolted on afterward. That's the gap I fill.
What I Build
Full Stack Web & SaaS Development
From multi-vendor e-commerce platforms to subscription-based SaaS products and headless CMS builds, I work primarily in Laravel, PHP, React, Vue.js, Node.js, Python, Django and WordPress, choosing the stack based on what the project actually needs, not habit.
AI Agents & Multi-Agent Systems
I design agentic workflows with LangGraph, CrewAI, LangChain, and MCP systems that can reason across multiple steps, use tools, retain memory, and carry out tasks with minimal supervision.
RAG & AI Knowledge Assistants
When a business needs its own data turned into answers, I build retrieval-augmented systems on LangChain, Pinecone, Qdrant, and pgvector semantic search, document Q&A, and citation-grounded responses that stay accurate to the source.
Voice AI Agents
Using LiveKit, Vapi, Retell AI, and Deepgram, I build real-time conversational agents that handle support calls, book appointments, and qualify leads without sounding like a script being read aloud.
AI-Integrated Web Systems
Rather than treating AI as a bolt-on feature, I integrate it directly into CRMs and business systems — lead scoring, automated responses, and dashboards that actually think, not just display data.

Why Work With Me
I don't build in isolated pieces. The web application, the data layer, the AI logic, and the deployment pipeline are designed as one system from day one which is why projects tend to move from idea to production without the usual rework. Whether you're starting a SaaS MVP from scratch, modernizing an existing platform, or adding AI to something that already works, I'll scope it around what you actually need, not what sounds impressive on paper.
Send me your current stack, your goal, and your data sources — I'll map out the simplest, most reliable way to get there.

Built the AI engine and platform behind Mipria, a French wellness brand offering AI-personalized herbal remedies for humans and pets, blending traditional phytotherapy with AI-driven personalization.

• Designed safety constraints specific to natural remedies, including age limits (users as young as 3), species differences for pets, and known ingredient interactions, keeping recommendations both personalized and safe.
• Built recommendation logic that stays strictly within wellness guidance, never presenting as medical advice.
• Built subscription and recurring-cure infrastructure (7-day, 15-day, 1-month, 2-month plans) plus the e-commerce layer for the general wellness shop.
• Treated privacy as a first-class requirement throughout, given the sensitive health-related data users share.
• Architected the system to scale to new ingredients and wellness categories without manual reconfiguration.

Built an AI Care Coaching Platform delivering personalized digital care coaching, end-to-end, owning both the AI engine and the full-stack application it runs inside.
• Built a conversational coaching agent that interprets user check-ins, maintains context on each user's progress over time, and generates personalized guidance and nudges dynamically, rather than pulling from a fixed content library.

• Built the backend architecture and APIs connecting user data, check-in history, and coaching state.
• Built the front-end experience end-to-end so the AI coaching engine, data layer, and interface work as one coherent system rather than separate pieces bolted together.
• Architected the platform to extend to new coaching domains without a system rebuild, keeping the coaching logic and product experience tightly aligned as it grows.

• Built a recommendation engine suggesting homes tailored to each user's browsing and saved-property behavior.

• Architected the backend so the AI automation layer plugs directly into the booking and calendar system in real time, rather than running as a disconnected notification service.
• Built the automation layer to scale across every business on the platform without manual per-client setup, and to support adding new AI-driven risk signals over time without rebuilding the core booking system.
