You don’t just need another developer; you need a business-first technical partner. Modern software development and enterprise AI aren't about running superficial prompt experiments—they require scalable architecture and a clear ROI. With 12 years of engineering experience (since 2014), I operate as a dedicated Technical Rescuer and CTO for my clients. I specialize in intercepting broken architectures, eliminating critical technical debt, and transitioning projects from a fragile "programmer mindset" to a robust, business-driven foundation across web, mobile, and AI domains. 🧮 How My Approach Mitigates Your Risk: I build enterprise-grade systems that cannot afford to fail. I focus on deterministic outcomes and risk mitigation: • Predictable Multi-Agent Systems: I design deterministic, error-free state machines that ensure AI agents behave predictably, moving beyond unreliable chatbot responses into true workflow automation. • High-Fidelity RAG & Vector Optimization: When building Retrieval-Augmented Generation (RAG) systems for confidential data, I utilize multidimensional vector optimization (Pinecone, pgvector) to guarantee high relevance and systematically eliminate model hallucinations. • AI-Assisted Development: My team and I leverage advanced, AI-assisted development workflows (Claude Code, Cursor, OpenClaw) to radically accelerate your Time-to-Market without sacrificing code quality or stability. ██ The Problems I Solve (And How We Solve Them) 🔧 Rescuing Broken Architectures & Full-Stack Development Inherited a failing project plagued by spaghetti code or unreliable vendors? I don't just patch problems; I restructure the foundation. From high-performance web platforms (React/Next.js, Node.js, Laravel) to cross-platform mobile applications, we build and rescue scalable, full-stack systems that perform under pressure. 🤖 High-Fidelity AI Voice & Omnichannel Concierges We engineer specialized, omnichannel AI voice stacks (Vapi, Retell AI, ElevenLabs) that drastically reduce administrative workloads. Combined with advanced RAG systems, these agents are secure, highly accurate, and directly tied to your operational workflows—whether on the web, mobile, or via telephony. ⚙️ Enterprise Scaling & ERP Unification When you outgrow your current setup, you need highly resilient cloud infrastructure. Following a strict architectural audit, we bypass unstable legacy workarounds. Whether we are building complex marketplace platforms like Shittest.me and Gryffin Inc., or executing deep process re-engineering using the Odoo platform, we unify your operations for maximum efficiency. 🛠 The Technology Stack • AI & Machine Learning: RAG Systems, Multi-Agent Workflows, LLM Fine-tuning, Vector Databases (Pinecone, pgvector) • Voice Orchestration: Vapi, ElevenLabs, Retell AI, Deepgram • Core Languages: Python, Node.js (NestJS/Express), PHP (Laravel) • Frontend & Mobile Architecture: React.js, Next.js, Vue.js, Mobile App Development • Infrastructure & Business Logic: AWS/GCP Cloud Architecture, Odoo ERP integration, API Architecture ██ How I Work I partner exclusively with businesses that view proper architecture as a long-term investment, not a quick hack. If you are dealing with technical bottlenecks that are slowing your growth, need to launch a complex web/mobile platform, or want to deploy a high-stakes AI system that absolutely cannot fail, send me a message with your current challenges and timeline. I will let you know honestly if I am the right fit, and we can discuss the most efficient path forward.

Full-stack developer and certified Bubble expert who takes AI-built MVPs to production. You vibe-coded your MVP with Claude, Cursor, or Lovable. It works beautifully, until real users show up. Then auth breaks, the database locks up, AI costs explode, and nobody on your team can read the code. I take broken AI-built MVPs to production, scale the ones that work, and build new ones that don't need rebuilding later. Bubble for speed, React or NextJS when you need full control. $100K+ shipped on Upwork across 47 projects. Top Rated Plus with 100% Job Success. Certified Bubble expert. I run an agency of 5 that has taken products from rough prototype to 10,000+ real users. Job portals, SaaS platforms, marketplaces, insurance tools, AI agents. ✅ What you hire me for 🔧 Rebuild AI-generated code to production standard. Take your Lovable, Cursor, Bolt, or v0 output and restructure it into real architecture. Proper auth, database design, testing, deployment pipelines. Your prototype keeps working while we rebuild underneath it. 🤖 AI agent and automation builds. Custom agents using Claude, OpenAI, n8n. Not chatbots. Real business workflows that eliminate 10 to 40 hours per week of manual work. One recent client saved $8K per month in operational costs. ⚡ Scale and optimize. Your MVP works but can't handle growth. Database indexing, caching, queue architecture, AI cost optimization, infrastructure migration. Fix bottlenecks before they kill your launch. 🏗️ Production-ready MVP from scratch. If you haven't vibe-coded yet and want to skip the prototype-then-rebuild cycle, I build MVPs that scale from day 1. Bubble when speed matters, React, NextJS, or Python when it doesn't. 🛠️ Tech Stack: Bubble | React | NextJS | Python | NodeJS | NestJS | FlutterFlow | OpenAI | Claude | n8n | Supabase | AWS | Docker | Stripe | PayPal 📋 My Process Discovery call → technical blueprint → weekly demos → launch → 30-day support.
