Solutions Architect
I architect and design scalable, secure, production-ready systems combining Generative AI, RAG, microservices, and distributed architectures. 10+ years building high-impact solutions for fintech, startups, and enterprises worldwide.
Featured work
alt.bank · novücard
Joined as Senior Engineer (2021), promoted to Tech Lead (2022), now Solutions Architect (2026). Lead solution architecture for credit and issuer platforms — multi-tenant, cloud-native, event-driven designs covering integrations, observability, security, and compliance. Architected credit decisioning systems and issuer flows, migrated issuer systems to a modern card processor, and helped position alt.bank as a Credit & Card-as-a-Service B2B provider. Scaled platforms supporting 90k+ users. Lead trade-off analysis across technology stacks and cloud architectures, and drive architectural POCs to validate new product features. Design and implement RAG pipelines that ground code generation in internal codebases and standards, power incident monitoring and on-call response with contextual runbook retrieval, and surface documentation, policies, and compliance requirements to reduce hallucinations in regulated contexts. Establish AI governance frameworks preventing data leakage and unauthorized exposure of sensitive financial information, and build LLM observability and guardrail layers tracking latency, cost, prompt drift, and output quality in production. Build autonomous and semi-autonomous agents for code review, incident triage, and documentation, with tool-use and human-in-the-loop checkpoints.
IT4process GmbH
Built hospital workflow automation platforms used by doctors, nurses, and administrative teams. Developed secure medical data processing services compliant with EU healthcare regulations. Delivered clinical web and mobile systems for B. Braun and RWTH Aachen University Hospital, with high-availability and strict security and audit requirements.
Scale Systems · DIVI.hub
Automated financial workflows, reducing manual work by ~80%. Improved the reliability and engagement of core platform modules.
Distributed Systems Laboratory · UFCG
Integrated Lenovo XClarity with Red Hat CloudForms for hybrid-cloud automation.

About
I'm a Solutions Architect with 10+ years of experience designing production-grade systems at scale. I specialize in Generative AI, distributed architecture, and fintech platforms, with hands-on expertise building SaaS products and AI-driven infrastructure. Former Tech Lead with strong soft skills in team building, mentorship, and cross-functional collaboration.
My recent work focuses on advanced AI applications: multi-provider LLM orchestration (Claude, OpenAI, Gemini), code-aware RAG systems, incident resolution automation, and production AI infrastructure. I've architected systems handling high-scale microservices, vector search, and complex billing/credit systems—all with enterprise-grade safety and compliance.
I thrive in multicultural environments, fluent in English, Portuguese, and German. My approach combines deep technical execution, strategic thinking, leadership skills, and focus on measurable business impact.
