Hire the Best Desk.com Developers

I build AI agents, automation systems, SaaS-style platforms, and API-driven web applications that help businesses automate operations, customer support, sales workflows, internal processes, and data-heavy tasks. I’m a Senior Software Engineer with 8 years of professional experience building backend systems, full-stack applications, REST APIs, microservices, dashboards, database-driven platforms, and third-party integrations. My focus is not just creating a quick demo. I build practical, production-ready systems with clean architecture, reliable backend logic, database integration, authentication, error handling, logging, deployment, and maintainable code. 𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 & 𝗦𝗮𝗮𝗦 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 I can also help with: • SaaS MVPs and internal business tools • Admin dashboards and customer portals • Full-stack web applications • Backend APIs and database design • Authentication, user roles, and payment workflows • Bug fixing, refactoring, performance improvement, and system cleanup 𝗔𝗜 𝗔𝗴𝗲𝗻𝘁𝘀, 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 & 𝗔𝗣𝗜𝘀 I can help you build: • AI agents for sales, support, operations, and internal workflows • AI chatbots connected to documents, websites, FAQs, CRMs, or databases • OpenAI / Claude API integrations • Workflow automation using APIs, webhooks, n8n, Zapier, or Make • RAG-based systems with document search and business logic • Custom API integrations with Stripe, Twilio, Gmail, Google Sheets, Airtable, Slack, Shopify, CRMs, and other platforms • Backend automation systems that reduce manual work and improve business operations My core stack includes Node.js, TypeScript, JavaScript, React, Next.js, REST APIs, PostgreSQL, MongoDB, OpenAI API, Claude API, Express.js, backend architecture, database design, API integrations, Docker, AWS, Azure, and Java/Spring Boot for enterprise-grade backend systems. 𝗪𝗵𝘆 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 𝗲𝗻𝗷𝗼𝘆 𝘄𝗼𝗿𝗸𝗶𝗻𝗴 𝘄𝗶𝘁𝗵 𝗺𝗲 • I think like a senior engineer, not just a tool operator • I can build both the AI layer and the backend system behind it • I understand APIs, databases, workflows, dashboards, and deployment • I care about reliability, security, performance, and maintainability • I focus on solving business problems, not just writing code Why so few reviews? Think of it like this — I’ve been cooking software for years, I just opened a new restaurant here 🙂 I completely understand that reviews matter, so we can start with a small “tasting menu” first. That way, you can sample how I work, communicate, and deliver before ordering the full course. If you need an AI agent, automation system, SaaS MVP, internal tool, API integration, or full-stack platform that actually works in the real world (not just in a demo video), I can help you build it properly — without the usual “it works on my machine” surprises.

SEO & AEO Specialist | Technical SEO | Google AI Overviews | LATAM & Global Google is no longer the only place your customers look for answers. They're asking ChatGPT, Gemini, Perplexity, and Google AI Overviews the exact question your business is meant to answer — and if your brand isn't part of that answer, a competitor's is. I'm José David Hernández. For 12+ years I've built SEO strategies that actually move revenue — and for the last several, I've been rebuilding those same strategies for a search landscape where AI systems, not just search engines, decide who gets found. 389+ completed projects. 20,000+ hours delivered on Upwork. Clients in 42 countries. 100% Job Success. Top Rated Plus. 216 reviews. THE REAL QUESTION TODAY It's not "how do we rank #1?" anymore. It's: when someone asks an AI which company to choose, does it mention yours? Answering that takes more than backlinks and blog posts — it takes entity clarity, structured data AI systems can parse, topical authority, and content built to be cited, not just indexed. The brands winning right now are the ones treating AI visibility as infrastructure, not an experiment. WHAT I DO 🔹 AI Search & Answer Engine Optimization (AEO/GEO) Visibility audits across ChatGPT, Gemini, Perplexity, and Google AI Overviews · citation and visibility gap analysis · entity and semantic SEO · question-based content architecture · conversational search research · AI search share-of-voice tracking 🔹 Technical SEO Full-site audits · crawlability & indexation · website architecture · Core Web Vitals · structured data / schema markup · JavaScript SEO · canonicalization · international SEO (hreflang) · site migrations · traffic-loss diagnosis and recovery 🔹 Content & On-Page SEO Topical authority strategy · content gap and competitor analysis · search-intent mapping · content briefs built for both readers and AI retrieval · commercial and service page optimization · internal linking strategy 🔹 Local SEO Google Business Profile optimization · multi-location strategy · citation building and NAP consistency · local landing pages · city/service keyword mapping · review strategy TRACK RECORD 🏆 12+ years in SEO, evolved into AI search 🏆 389+ completed projects 🏆 20,000+ hours delivered on Upwork 🏆 Clients across 42 countries 🏆 100% Job Success Score, Top Rated Plus 🏆 216 client reviews TOOLS & PLATFORMS Ahrefs · SEMrush · Screaming Frog · Google Search Console · Google Analytics · Google Tag Manager · BrightLocal · DataForSEO · WordPress · Shopify · WooCommerce · plus AI-driven tools for content testing, entity mapping, and AI-visibility tracking INDUSTRIES I'VE WORKED WITH SaaS and technology · eCommerce and DTC brands · real estate · law firms and legal services · professional services agencies · local and multi-location service businesses · healthcare and clinics · hospitality WHO I WORK BEST WITH SaaS and tech companies competing for category-defining searches, where organic and AI visibility directly influence the sales pipeline eCommerce brands that need stronger visibility across product, category, and AI-driven search Law firms, real estate, contractors, and other local or multi-location businesses competing through local search and AI-powered recommendations Agencies that want an experienced SEO/AEO specialist to work independently or plug into their existing team HOW I WORK No vanity metrics. My process is straightforward: Audit — I map your current visibility across Google and AI search engines, and where your competitors are outperforming you Strategy — a prioritized plan focused on the opportunities with the highest realistic impact, not busywork Execution — technical fixes, content, structured data, and entity building, done right the first time Reporting — transparent, business-outcome reporting: visibility, qualified traffic, authority, and citations — not just rankings I work independently or collaborate directly with your developers, writers, designers, and marketing team. Bilingual in English and Spanish, with deep experience across both the LATAM and global markets — so language and cultural nuance are never a gap in strategy or execution. HOW TO START Send me three things: Your website Your top 3 competitors The query, product, or service you most want your brand to own — in Google and in AI search I'll show you exactly where you're losing visibility and where the biggest opportunity is. If you need basic SEO, there are plenty of freelancers for that. If you want to be the answer AI systems give — and still dominate traditional Google — let's talk. WHY CLIENTS STAY I don't disappear after the audit. I stay hands-on through execution, adjust strategy as AI search evolves, and communicate clearly at every stage — no jargon, no guesswork, just visibility you can measure month over month. #SEO @LOCALSEO#AISEO #AEO #GEO #SEOExpert #TechnicalSEO #LocalSEO #GoogleAIOverviews
