Building the systems that determine how enterprise brands appear in ChatGPT, Gemini, and the next generation of AI agents sits exactly at the intersection of my +20y background in full-stack software engineering and my recent work on AI-native platforms, LLM integrations, and web-scale content analysis. - -A representative example is my independent project, Rodado, the biggest Brazilian data platform maintaining and exposing ~730 Brazilian public datasets for analytics and AI. It manages approximately 1TB of Parquet data on S3-compatible storage, integrates DuckDB for analytics, provides REST APIs and semantic search, and includes an LLM-powered natural-language-to-SQL interface exposed through MCP tooling — making the entire platform directly consumable by AI agents. Building it required scalable ETL pipelines, robust metadata management, secure APIs, query optimization, and designing for exactly the kind of AI-driven discovery that brand visibility in AI experiences demands. - -I work AI-natively day to day: AI coding agents such as Claude Code are a core part of my development workflow, and I have built agentic systems end-to-end, including an autonomous framework that closes the loop between knowledge, hypothesis, experiment, and analysis. On the visibility side, my HelvetiScan project scanned and mapped 2.5M+ Swiss .ch domains — HTTP, DNS, TLS, WHOIS, and content — with sector classification and scoring, which is web presence analysis at national scale and the same class of problem as reasoning about brand visibility data across SEO/GEO platforms. - -Throughout my career, I have designed and delivered production systems using Python, TypeScript, Ruby, SQL/NoSQL databases, REST APIs, cloud infrastructure, CI/CD, and modern software engineering practices. At Swisscom, I helped modernize mission-critical internal platforms and CI/CD pipelines supporting high-availability telecommunications infrastructure. Previously, at EDGE Empower, I led a multidisciplinary engineering team, redesigned a Python monolith into a parallelized TypeScript architecture that reduced processing time by 98%, and shortened CI/CD pipelines from 14 minutes to 4 minutes — automated quality gates that scale without relying on individual discipline. - -I enjoy operating in ambiguity: as an independent consultant I drove 40+ projects from unclear briefs to shipped products, and I like sharing what I learn through mentoring, documentation, and teaching. I hold a Bachelor's degree in Computer Science, a Master's degree in Information Systems focused on knowledge representation and reasoning — a foundation that maps naturally onto how LLMs represent and retrieve knowledge about brands — and additional postgraduate studies in Data Science. - -I am based in Basel, immediately available, hold a Swiss B permit and a Portuguese passport. - -Thank you for your consideration. - -Kind regards, -Rafael Polo -14-July-2026 -extrapolo.com / linkedin.com/in/rafaelpolo / github.com/rafapolo diff --git a/motivation1.md b/motivation1.md deleted file mode 100644 index 07dbe01..0000000 --- a/motivation1.md +++ /dev/null @@ -1,21 +0,0 @@ -Dear Roche hiring team, - -I am applying for the Principal Software/Data Engineer position in Basel because the role fits the work I do best: designing secure, scalable production systems that connect data, software architecture, AI-enabled workflows, and product delivery. I am based in Basel, hold EU citizenship, do not require a work permit, and bring more than 20 years of software engineering experience across Switzerland, Germany, Greece, Brazil, and Portugal. - -My background combines platform engineering, data pipelines, front-end interfaces, back-end APIs, CI/CD, and production operations. Most of my systems have used PostgreSQL or compatible relational database patterns, and I am comfortable designing schemas, query paths, APIs, and operational safeguards around live data. I have built React/TypeScript interfaces, Python/Ruby/TypeScript back ends, Docker-based deployments, AWS services, Kubernetes environments, and CI/CD workflows. - -A strong example is my independent project rodado/baseldosdados: a production data platform around one of the largest Brazilian public-data mirrors exposed through MCP-style tooling. It covers hundreds of public datasets, approximately 675 GB of Parquet+zstd data, DuckDB, S3-compatible object storage, semantic table search, an LLM natural-language-to-SQL workflow, a programmatic SQL API, and read-only access controls. The system handles domains such as health, education, elections, companies, public contracts, employment, and demographic indicators. Building it required partition-aware query design, join-key modelling, result validation, credentials isolation, logging, reproducible schema metadata, and careful handling of personal identifiers such as CPF/CNPJ. - -This is the same engineering pattern I would bring to Roche: robust software architecture for data- and ML-driven products, reliable APIs and pipelines, usable interfaces for complex outputs, and disciplined production practices. I understand the difference between a promising prototype and a system that teams can trust, operate, monitor, and extend. I also enjoy the product side of that work: balancing technical trade-offs with user impact, business value, maintainability, and delivery speed. - -At Swisscom, I worked on modernization of mission-critical internal platforms and CI/CD pipelines for high-availability telecom infrastructure. At EDGE Empower, I led a small engineering and UX team, built a PayTool that reduced processing time by 98%, and shortened a CI/CD pipeline from 14 minutes to 4 minutes. Across consulting work, fintech/KYC systems, civic data platforms, and investigative data tools, I have collaborated with UX designers, product managers, researchers, journalists, and technical teams to translate ambiguous needs into working software. - -I also match the academic and communication requirements: I hold a Bachelor in Computer Science, a Master in Information Systems focused on knowledge representation and reasoning, and a postgraduate degree in Data Science for Finance. I am used to explaining complex systems clearly, mentoring others, documenting reusable patterns, and working across cultures in English, Portuguese, Spanish, and German B1. - -While I have not worked directly inside clinical development, I have worked in regulated and sensitive-data contexts including Swiss data protection, fintech/KYC, telecom infrastructure, and public-sector data. I understand the importance of auditability, reproducibility, access control, privacy, and conservative engineering when software supports important decisions. I would bring that mindset to Roche's Product Development Data Sciences environment and learn the clinical and GxP-specific context with discipline. - -What attracts me most is the Innovation Accelerator's position between strategy, experimentation, and production. I enjoy exploring emerging technologies, validating them through real use cases, and making the engineering decisions that allow pilots and MVPs to become secure, maintainable products. - -Sincerely, - -Rafael Polo diff --git a/tasks/to-update.md b/tasks/to-update.md index d10656d..0b464b4 100644 --- a/tasks/to-update.md +++ b/tasks/to-update.md @@ -1,108 +1,16 @@ # CV & application materials — to update -Audit date: 2026-07-27.
