I've spent 5+ years building ML / AI systems that work in production, not just in notebooks. If you need a RAG pipeline that actually retrieves the right answers, an LLM integration that handles edge cases gracefully, or an AI agent that automates real workflows, that is exactly what I do every day at scale. Results from recent work: • Built LLM-based automation for one of the largest airlines in LATAM using LangChain and FastAPI, reducing human-hours on repetitive processes by ~40% • Developed a GenAI platform at a company serving millions of daily users (Rappi), including LLM fine-tuning that improved first response time by ~20% • Designed RAG systems with PGVector and ChromaDB for internal knowledge retrieval across enterprise teams • Implemented AI Automation workflows using platforms like n8n. • Deployed production microservices with FastAPI and Docker on GCP and AWS • 100% Job Success Score on Upwork. Every client rated 5 stars. What clients hire me for: • RAG systems and knowledge bases (document ingestion, hybrid retrieval, reranking) • LLM integration and fine-tuning (OpenAI, open-source models, domain-specific training) • AI agents and workflow automation (LangChain, LangGraph, tool-use pipelines) • Production ML microservices (FastAPI, Docker, cloud deployment) • AI strategy and architecture consulting Technical stack: • LLM/GenAI: LangChain, LangSmith, LangGraph, RAG, Prompt Engineering, Fine-tuning • ML/NLP: PyTorch, scikit-learn, sentence-transformers, embeddings, vector databases • Backend: Python, FastAPI, PostgreSQL, PGVector, Docker • Cloud/MLOps: GCP (VertexAI, Storage), AWS (S3), Apache Airflow • Data: SQL, Pandas, NumPy, Snowflake, BigQuery I work at a global consultancy (Thoughtworks), building AI solutions for enterprise clients during the day, and take on select freelance projects that align with my expertise. I bring the same production standards, documentation, and communication quality to every engagement. Published researcher (Springer, 2025). Two engineering degrees, including a B.Eng in Artificial Intelligence. Astronomer-certified in Apache Airflow. If your project involves LLMs, RAG, or production AI, send me a message with the details. I respond within a few hours and can usually scope a first milestone within 24 hours.

Computer Science Engineer, Full stack developer and AWS architect, a great enthusiast for TDD clean code and good software development practices, in search of challenging projects that allow me to expand my skills.

Most SEO audits end up gathering dust on a hard drive. Why? Most agencies identify the problems but lack the technical confidence to edit the code and fix them. I bridge that gap. I don't just report errors; I engineer the solutions directly into your infrastructure. If you are reading this, you are likely facing a specific, painful bottleneck: a sudden drop in organic traffic after a Core Update, critical crawl errors that developers can't resolve, a WordPress site failing Core Web Vitals, or the urgent need to adapt to AI Search (GEO). You don't need another generalist with a checklist. You need a Technical Partner who combines Data Science with Full-Stack Development. 💡 THE "DEV + SEO" ADVANTAGE I operate at the intersection of marketing and engineering. While others rely on basic plugins, I use Python, PHP, and SQL to perform deep-level optimizations: As a Developer: I manually refactor bloatware code (JS/CSS) to ensure your site is lightweight and passes Google's INP (Interaction to Next Paint) metrics. As a Security Specialist, I harden your server headers and database to prevent malware and negative SEO attacks that destroy rankings. As a Data Analyst: I use Python (Pandas/Advertools) to audit 100,000+ pages and uncover semantic gaps that tools like Ahrefs or SEMrush miss. 🚀 COMPREHENSIVE SERVICE CATALOG 1. ADVANCED TECHNICAL SEO & ARCHITECTURE I translate confusing error logs into a pristine, crawlable infrastructure that maximizes your Crawl Budget. Indexing Strategy: Resolving complex Canonical Loops, "Crawled - Currently Not Indexed" errors, Orphan Pages, and infinite 404/301 Redirect Chains. Crawlability Control: Advanced configuration of robots.txt, XML Sitemaps, and handling Faceted Navigation parameters to prevent index bloat. JavaScript SEO: Ensuring your React/Angular/Vue content is fully rendered and indexed by Googlebot (SSR/Prerendering solutions). International Growth: Precise implementation of hreflang tags and sitemaps for multi-language and multi-regional architecture. 2. WORDPRESS PERFORMANCE ENGINEERING (WPO) Speed is revenue. I optimize your site to hit the "Green Zone" (90+) in PageSpeed Insights without breaking functionality. Core Web Vitals Mastery: Fixing LCP, CLS, and the new INP metric via Critical Rendering Path optimization and asset minification. Server-Side Optimization: Configuring Object Caching (Redis/Varnish), GZIP/Brotli compression, and Cloudflare Enterprise rules (Workers/Page Rules). Database Hygiene: Writing custom SQL queries to clean wp_options, remove transient data, and reduce Time to First Byte (TTFB). 3. AI SEARCH & GENERATIVE ENGINE OPTIMIZATION (GEO) The search landscape is shifting to AI Overviews (SGE) and ChatGPT. I prepare your brand for 2025. Entity Stacking: Structuring your content around Topic Clusters and Entities to establish high E-E-A-T (Experience, Expertise, Authoritativeness, Trust). Structured Data: Coding custom JSON-LD Schema Markup (Organization, Product, FAQ, Review, HowTo) to help AI models understand your data and capture "Position Zero." Semantic Analysis: Using NLP (Natural Language Processing) tools to optimize content relevance for both users and Large Language Models (LLMs). 4. ANALYTICS & DATA INTEGRITY Server-Side Tracking: Implementing Google Tag Manager (GTM) Server-Side for accurate data collection in a cookie-less world. GA4 Configuration: Custom events, conversion tracking, and BigQuery integration. Reporting: Building automated Looker Studio dashboards that track real ROI, Revenue, and Lead Quality—not just vanity metrics. 🛠 MY TECHNICAL METHODOLOGY I don't guess; I test. My process is rooted in the scientific method. Diagnostic: I run a 200-point audit using Screaming Frog (Custom Regex extraction), Log File Analysis, and manual code review. Strategy: I prioritize fixes based on "Effort vs. Impact" to give you the fastest ROI. Execution: I deploy fixes in a staging environment first. I write the PHP functions, clean the CSS, and configure the server. Verification: I monitor GSC and server logs to confirm the fix is indexed and traffic is recovering. 💻 TECHNOLOGY STACK CMS: WordPress (Custom Theme Dev), WooCommerce, Shopify, Webflow, Magento. Languages: PHP, Python, HTML5, CSS3, JavaScript (Basic), SQL. Tools: Screaming Frog SEO Spider, Sitebulb, DeepCrawl (Lumar), Ahrefs, SEMrush, Moz, Majestic, Google Search Console, Google Analytics 4. Are you ready to stop patching problems and start engineering growth?
