Hire the Best Pentaho Developers in Buenos Aires, AR

I help companies eliminate manual work and connect their systems through automation, integrations, and data engineering built on solid cloud architecture. Over 5+ years building backend systems and cloud infrastructure for Fortune 100 clients, I deliver: Automation & Integrations: Custom n8n workflows, Stripe payment architecture, and REST/Webhook API connections that replace manual processes with reliable pipelines. AWS & Cloud Infrastructure: Scalable, serverless architecture (Lambda), infrastructure design, and cost/resource optimization. Data Engineering & Custom Software: High-performance ETL pipelines, database design, and tailored backend systems (Java/Spring Boot) built for production load. I work end-to-end - architecture, scoping, delivery, and handoff - with clear communication throughout. Tell me what's slowing your operations down, and let's automate it.

I am a Systems Engineer with more than 10 years of overall experience in different Business Intelligence-related roles. I have been involved on projects related to all technical aspects of a BI solution (from setting up a cloud server up to some basic visualization reports) and hope to apply this experience to solve concrete business questions or automation requests. Key skills and experiences: - Highly proficient in SQL, having worked part of my experience as Teradata DBA and the rest as a frequent user (from analysis to table design and performance optimization) - Experience with various ETL tools (Pentaho, Informatica PowerCenter, Ab Initio) and also with Python scripts used for integration purposes - Ability to design a BI solution end-to-end starting from the required KPIs and datapoints, and implement via an AWS setup (EC2, Amazon S3, Amazon Redshift, Amazon QuickSight) with one real-life success story - Acute business sense resulting from years of speaking with business stakeholders from various trades (financing, banking, online commerce) - Hands-on experience with Salesforce CRM (as an admin and some basic development/Apex) as a result of the integration with our BI setup in a previous role

I orchestrate and engineer the AI agents that build the complex engines that run businesses. After years as a full stack developer, I’ve learned that the hardest part of engineering wasn't writing code (we don't code anymore!), it’s architecting the system so it doesn't break six months down the line, due to bad decisions or AI slop. You are likely here because you’ve outgrown off-the-shelf tools or are tired of non-responsive junior devs. Maybe your data is trapped in silos, your manual processes are costing you money, or you have a development team that needs senior leadership to get a difficult project over the finish line. I act as a technical partner. I don’t just take tickets; I look at your business logic to understand your business and what is Really hurting, find the bottlenecks, and build the custom infrastructure required to fix them. What I actually do I specialize in high-complexity B2B environments where data integrity and workflow automation are critical. 1. Custom CRM & B2B Platforms Most businesses try to force their unique workflows into Salesforce or HubSpot and fail. I build custom CRM or custom apps for a known CRM using the API and SaaS platforms that fit your operations. I focus on scalable architecture, secure role-based access, and efficient databases that can handle heavy B2B transaction loads. 2. Connecting Systems (ETL & Integrations) Data is useless if it’s messy or stuck in the wrong place. I have deep experience building ETL pipelines to move, clean, and synchronize data between your legacy systems and modern cloud infrastructure. whether it’s a complex API integration or a massive database migration, I ensure your data remains accurate. 3. Real Automation (n8n) I’m a heavy user of n8n because it allows for sophisticated, self-healing workflows. I don't just "zap" things together. I build orchestrated automations with error handling and logic branches that replace entire manual departments, from invoicing and logistics to onboarding and reporting. 4. Applied AI I move past the hype of AI to build tools that actually work. This usually means integrating LLMs (any provider) into your existing data flow to parse unstructured documents (PDFs, emails), categorize leads, or build intelligent search agents for your internal teams. 5. Leading Your Tech Team If you already have developers but they lack direction, I step in as a Tech Lead. I implement code reviews, and architectural standards to turn a chaotic group of coders into a disciplined product team. My Tech Stack I believe in using the right tool for the job, but my core expertise lies in: Languages: [PHP/ Javascript-Typescript] Frontend: [React / Svelte] Databases: PostgreSQL, MySQL, Redis, SQLite. Tools: n8n, Docker, AWS, DigitalOcean, Cloudflare Workers/R2/D1 Git. How I Work I value clarity over complexity. When we start, I won't just say "yes" to every feature request. I will challenge assumptions to make sure we aren't building technical debt. We talk strategy: I need to understand the business goal, not just the code requirement. I architect first: We map out the data flow to ensure scalability. I build transparently: You get clean, documented code that you truly own. If you have a project that is too complex for a junior developer to handle, let’s have a chat.

I'm a Senior Software Engineer and Tech Lead with 10+ years building production-grade PHP/Symfony systems — from clean microservices to complex DDD backends with event sourcing, CQRS, and hexagonal architecture. I've worked across the full stack: APIs with API Platform, React Native mobile apps, Docker-based infrastructure, CI/CD pipelines, and observability setups. I know how to take a codebase from technical debt chaos to a well-structured, testable, scalable system. Some concrete results from recent roles: • Reduced GraphQL response payloads by 40% at Svitla Systems, cutting load times and improving UX. • Improved P99 performance by 70% at WeKnow through query optimization and custom EasyAdmin components. • Led a Symfony/PHP version migration at Chargebacks911, improving delivery speed and reducing bug rate. • Drove lead time under 5 days and time-to-market down to 1 week at Aper with AI-assisted code review (CodeRabbit) and static analysis tooling. • Designed a RabbitMQ-based messaging architecture at Linio that handled marketplace notifications with resilience and fault tolerance. I apply SOLID principles, write tests (PHPUnit, PHPSpec, Behat), and integrate tools like PHPStan (level 9), Rector, and ECS from day one — not as afterthoughts. If you need someone who ships clean, maintainable code and also understands the bigger picture (architecture, team workflows, CI/CD), let's talk.

Full Stack Developer with more than 11 years of experience, specializing in building robust and scalable web applications. I have a strong command of backend technologies like PHP (with frameworks such as Laravel and Symfony) and TypeScript (using Node.js with frameworks like Express.js and NestJS). This combination allows me to design high-performance server architectures, leveraging TypeScript's strict typing to build reliable APIs and microservices. On the frontend, my experience is centered on React and TypeScript, where I develop dynamic and intuitive user interfaces. I'm proficient in managing application state with libraries like Redux or Zustand, and I efficiently apply styling with Tailwind CSS or Styled Components to deliver high-quality user experiences. In addition to my development skills, I possess strong sysadmin and DevOps capabilities. My experience includes using Docker and Docker Compose for containerization and application deployment, as well as Ansible for configuration management and automation. My development stack is complemented by knowledge in Python for scripting and automation, as well as databases (SQL and NoSQL), the development of RESTful APIs and GraphQL, and version control with Git. I am a proactive professional, focused on problem-solving and delivering complete, efficient, and maintainable solutions. ----------- .
