Hi, I am an AI and Full-Stack Engineer with over ten years of experience designing and building intelligent, scalable, and production-ready software systems. I help startups and growing businesses turn complex problems into simple, smart, and automated solutions. My goal is always to save time, improve decision-making, and create applications that scale effortlessly. I specialize in Python with frameworks like Django, FastAPI, and Flask for backend development. I write clean, maintainable code with a focus on performance, reliability, and scalability. I also work with React and Next.js to deliver smooth and responsive user interfaces. Alongside full-stack development, I specialize in natural language processing and Generative AI. I build applications using large language models, LangChain, and LlamaIndex. I develop retrieval-augmented generation systems, conversational AI, semantic search, knowledge base automation tools, and other AI-powered solutions that turn data into insight and workflows into intelligent automation. I have hands-on experience with transformer models such as GPT, LLaMA, Mistral, Claude, Gemini, and Qwen. I integrate them using fine-tuning, prompt engineering, embeddings, and custom API pipelines. I work with vector databases like Pinecone, Weaviate, FAISS, and ChromaDB to enable context-aware intelligence and fast data retrieval. I have delivered end-to-end solutions including AI-powered SaaS platforms, custom dashboards, automation systems, and text-to-SQL tools. I focus on strong backend architecture, intelligent AI logic, and seamless user experiences. I also have experience deploying applications on cloud platforms such as AWS, GCP, and Azure using Docker and CI/CD pipelines to ensure reliability and scalability.

If you're evaluating multiple developers, let me make your decision a little easier. Building software isn't just about writing code; it's about making the right technical decisions from the start. A poor architecture, the wrong tech stack, or shortcuts taken early can cost months and thousands of dollars later. That's where I come in. For the past 9+ years, I've been helping startups, founders, and businesses turn ideas into scalable digital products. Whether it's an AI-powered SaaS platform, a custom web application, or a mobile app for iOS and Android, my focus is always the same: build software that's reliable, maintainable, and ready for real users. I don't see myself as someone you hire to complete tasks. I work as a technical partner who takes ownership of the product, understands the business behind it, and helps make the right decisions throughout the development process. My Expertise: AI & Automation: AI Agents & AI Assistants Voice AI & Conversational Systems OpenAI, Claude & Gemini Integrations RAG Applications Workflow Automation AI-Powered SaaS Platforms Web & SaaS Development: React.js Next.js Node.js NestJS Laravel Python Multi-Tenant SaaS CRM & ERP Systems Admin Dashboards REST APIs Real-Time Applications Mobile App Development: React Native Flutter Native iOS & Android Firebase Supabase Cross-Platform Applications Technologies React • Next.js • Node.js • NestJS • Laravel • Python • React Native • Flutter • Swift • Kotlin • Firebase • Supabase • PostgreSQL • MongoDB • AWS • Docker • Kubernetes • OpenAI • Claude • Gemini • LangChain • Stripe • REST APIs • WebSockets What You Can Expect: Clean, scalable architecture Clear communication throughout the project Production-quality development Secure and maintainable code On-time delivery with long-term support A business-first approach, not just feature development I've worked on AI platforms, SaaS products, healthcare solutions, marketplace applications, CRM systems, business automation tools, and enterprise software. Every project is built with long-term growth in mind, so you don't have to rebuild as your business scales. If you're looking for someone who can take ownership, solve complex technical challenges, and help turn your vision into a successful product, I'd be happy to discuss your project. Let's build something great together.

Expert-Vetted (Top 1%) AI engineer — $1M+ earned building production AI agents, RAG systems and n8n/Make automations for US companies. Replies within hours. Recent: recovered 33% of lost Meta conversions for a DTC brand; cut a client's lead triage by 70% with a Claude agent. What I do best: - AI agents and RAG systems on Claude and OpenAI APIs — lead qualification, knowledge search, support triage, content — with guardrails and monitoring so they're reliable in production, not brittle demos. - Workflow automation with n8n, Make and Zapier, connecting HubSpot, Slack, Notion, Gmail and your CRM. - Full-stack builds in React, Next.js, Node and TypeScript on AWS, Supabase and Vercel — for when the AI needs an app around it. Recent results: - Recovered ~33% of lost Meta Purchase events for a DTC store by moving conversion tracking server-side (Meta CAPI). Match quality 95–100%. - Built a lead-qualification agent (Claude + n8n) that scored leads, enriched the CRM, and drafted follow-ups — cut manual triage by ~70%. - AI Intake & EHR integration for a telehealth platform — automated patient onboarding and reduced manual data entry. For larger projects I bring in my team at OpenSource Technologies, so you get continuity and coverage rather than a single point of failure. I also cover WordPress/WooCommerce/Shopify, Stripe/fintech, Web3/Solana, and security reviews when the work touches them. Forbes Technology Council member.

I design and build production-ready web and mobile products that are meant to be used, scaled, and relied on. For over 12 years, I’ve worked hands-on across SaaS platforms, internal systems, marketplaces, dashboards, and AI-driven features from architecture and integrations to deployment and long-term stability. My focus is simple: building systems that plug into real business workflows, work with the tools teams already use, and actually ship without becoming technical debt. I stay close to the code, close to the product, and focused on outcomes.
