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

The internet is where my clients are. I'm picky about projects because bad fits waste everyone's time, including yours. Currently have room for 2, maybe 3 if the work is interesting enough to skip weekends. I once had a client cry over a business card. Another yelled at me because his website loaded in 4 seconds instead of 2. I count both as wins. That tells you everything. I care about how things feel in your hand and how they work under the hood. Most people pick one. I picked both because I couldn't stand watching good design die in bad development, or great code wrapped in ugliness. Started in 2012 with ink and paper. Packaging that sold products before anyone read the label. Logos that worked on billboards and favicons. Print taught me restraint: if it doesn't work at 1 inch, it doesn't work. Then screens ate the world. Clients started asking for "the same feeling, but online." I learned to build what I designed, not because I wanted to code, but because I couldn't trust anyone else to protect the details. Now I do both. One brain, no broken telephone between design and development. 🟍 The work: ▶ Visual identity → logos, packaging, print systems that actually get printed (I know paper weights, color profiles, which printers won't ghost you) ▶ Digital presence → websites that load fast, rank higher, convert visitors. WordPress, Shopify, Squarespace, Webflow, Wix (I know which one fits your actual life, not my preference) 🟍 Recent scars & wins: 🙮 Rebranded a Houston coffee roaster → new bags on shelves, Shopify store for wholesale, owner stopped answering 2am reorder emails... 🙮 Law firm that looked like every other law firm → custom typography, real team photography, green instead of navy, WordPress site that loads before you blink... 🙮 Yoga instructor who wanted "just a logo" → full identity with texture and breathing room, Squarespace site that felt like her classes: grounded but floating What I actually do: Translate what your business is into what people see, then make it work everywhere. Print, screen, phone, packaging. No "strategy decks." No handing you off to a developer who ruins the spacing. I design it, I build it, I answer when it breaks. Send me your mess; visual, digital, or both. I'll tell you what's salvageable and what needs to burn. menos

But when was the last time you used something that made you think, "This actually gets me"? That's the gap we're closing. We Build Products People Actually Want to Use. Not because they have to. Not because it's "good enough." But because it solves a real problem so elegantly that going back feels impossible. Web apps. Mobile apps. AI-powered automation. SaaS platforms. WordPress sites that convert. WooCommerce stores built to sell. SEO-optimized content that ranks. Banner and web designs that stop the scroll. Whatever you need — we build it to feel intuitive, perform flawlessly, and scale without falling apart. From pixel-perfect HTML/CSS interfaces and Node.js backends to cloud-computed data pipelines and WordPress/Elementor builds — our stack is as broad as your ambition. We handle everything from WordPress Design and SEO Writing to full-scale SaaS architecture and AI automation, all under one roof. Our Philosophy Simple beats complicated. Every time. We strip away the noise so your users focus on what matters. Your business drives the tech — not the other way around. Innovation should be invisible: the best technology doesn't announce itself, it just works faster, smarter, and more reliably than anything before it. What We Actually Do We partner with businesses to build new products from the ground up, modernise legacy systems, automate intelligently with AI, launch scalable SaaS platforms, optimize for search with data-driven SEO strategies, and connect everything — APIs, cloud services, third-party tools — seamlessly. We don't just write code. We ask the hard questions, challenge assumptions, and iterate until the solution feels obvious all along. Why We're Different The market is drowning in agencies churning out generic MVPs. What's rare? Teams who genuinely care about craft — balancing innovation with practicality, speed with reliability, and function with feeling. We're obsessed with building software and digital experiences that don't just check boxes — they earn loyalty. Who We're For If you want a quick fix or the cheapest option → We're not your team. If you want a product, a website, or a digital presence that starts strong and gets better over time — one your users, your team, and your investors are proud of — let's talk. menos
