My core focus is designing, building, and deploying AI-driven systems—from LLM-powered agents and voice assistants to data-aware automation pipelines that integrate seamlessly with production applications. I work extensively with large language models (LLMs), retrieval-augmented generation (RAG), vector databases, embeddings, tool-calling frameworks, and agent orchestration patterns to create systems that reason, act, and scale reliably. On the backend, I build high-performance APIs and services using FastAPI, Flask, Node.js, and Django, with strong experience in async architectures, background workers, and event-driven systems. I regularly work with PostgreSQL, MySQL, Redis, MongoDB, and Neo4j, and design robust data layers using SQLAlchemy, Prisma, and ORM/DAO patterns. For AI workloads, I integrate OpenAI, Anthropic, Ollama, ElevenLabs, and custom inference pipelines, alongside Qdrant, Pinecone, FAISS, and hybrid search setups. On the frontend, I build modern, scalable interfaces using React, Next.js, Vite, Tailwind CSS, and TypeScript, with a strong emphasis on UX for AI-powered tools (real-time streaming, agent state visualization, conversation flows, and admin dashboards). For mobile, I work with React Native and cross-platform architectures to bring AI features directly into user-facing apps. Automation is a major part of my work. I design end-to-end business automation systems using Make.com, n8n, webhooks, cron jobs, message queues, and direct API integrations. This includes automating CRM workflows, email systems, call routing, lead qualification, reporting, and data synchronization across platforms like Twilio, Slack, Google Sheets, Stripe, Shopify, and internal tools. I’m highly experienced in AI voice agents and real-time systems, integrating Twilio, speech-to-text (STT), text-to-speech (TTS), streaming APIs, and conversational state management to build production-ready voice and chat agents. I also work on computer-vision and multimodal pipelines, combining vision models, tracking, and sensor data for advanced use cases. From an infrastructure and MLOps perspective, I deploy and scale systems using Docker, Linux servers, cloud VPS, CI/CD pipelines, and GPU-accelerated environments. I care deeply about observability, logging, error handling, security, and cost optimization in AI systems. Above all, I love turning business problems into automated, intelligent systems—reducing operational friction, increasing efficiency, and building products where AI is not a feature, but a core capability. If you need AI agents, automation pipelines, or full-stack systems that actually work in production, that’s exactly what I build. menos -

I’m a full-stack developer with strong expertise in Artificial Intelligence (AI), Machine Learning (ML), and Large Language Models (LLMs). I build smart, data-driven applications that integrate intelligent automation, natural language processing (NLP), and predictive analytics to deliver innovative, scalable solutions for businesses.

On the frontend, I develop modern, high-performance web and mobile applications using ReactJS, React Native, Swift/SwiftUI for iOS, and Kotlin/Jetpack Compose for Android. I also specialize in custom WordPress development, from theme and plugin creation to full-scale, tailored CMS solutions, ensuring functionality matches your exact needs. My UI/UX toolkit covers HTML, CSS, JavaScript, jQuery, and Bootstrap, with a focus on clean, user-friendly design. Beyond application development, I have hands-on experience with Blockchain-based applications, Cloud management (AWS, Azure, Google Cloud), and DevOps workflows (CI/CD pipelines, containerization with Docker/Kubernetes, and server automation). My approach is to combine technical expertise with an understanding of business goals, delivering high-quality, scalable, and future-ready solutions that not only meet but exceed client expectations. menos -
