Designed and implemented secure CI/CD infrastructure for a financial institution with 1,200+ repositories and 3,000+ build artifacts across 15+ technology stacks (Java, React, Salesforce, on-premise, mobile, and more). Built reusable pipeline libraries covering SAST, DAST, quality gates, policy-as-code, and container hardening — enabling consistent secure delivery across the entire engineering organization.

• → Standardized CI/CD pipelines across 1,200+ repositories and 3,000+ artifacts — 15+ build types including Java, React, Docker, Salesforce, Kubernetes, Cloud Run and on-premise
• → Reusable GitHub Actions libraries with SAST, DAST, quality gates, policy-as-code and secret management
• → Container hardening, dependency scanning and golden path templates reducing defects across multi-stack deployments
• → Security pipeline architecture ensuring regulatory compliance (CNBV/Banxico) for a regulated financial institution

Founded and led the Architecture Squad — a cross-functional governance body that defined architecture standards, maturity frameworks, and reference architectures adopted across 7+ engineering teams. Designed cloud-native solutions on AWS (CodePipeline, CodeBuild, ECS, Lambda, Glue) and built an Internal Developer Platform (IDP) on Kubernetes enabling self-service infrastructure. Drove organizational alignment through ADRs, C4 documentation, and a 5-level maturity model covering architecture, security, infrastructure automation, and observability.

• → Founded Architecture Squad — governance model with maturity matrix (5 levels × 8 dimensions) and technology catalog adopted by 7+ teams
• → Reference architectures (DDD, EDA, hexagonal) and ADR/C4 documentation standards rolled out organization-wide
• → Internal Developer Platform (IDP) on Kubernetes — golden paths, multi-stack self-service deployments, AWS CodePipeline + CodeBuild pipelines
• → Batch system processing 1M employment history records in under 3 minutes — AWS Glue Jobs + RDS + Feature Store integration for ML workloads
• → Karpenter dynamic node scaling, centralized authentication layer, and Dynatrace observability with SLO/SLI definition
• → OpenShift transition strategy and coached 7+ engineering teams on architecture practices and cloud-native delivery

Led architecture and delivery across 3 multidisciplinary squads building customer-facing and internal systems for retail operations spanning 100+ stores. Collaborated with an external consultancy on solution design, standardizing infrastructure on AWS and virtualized environments. Introduced observability practices and proposed a microservices improvement initiative that reduced critical incident recovery times.

• → Coordinated 3 squads delivering customer-facing optimizations and internal admin systems (React, TypeScript, Node.js)
• → AWS API Gateway + Docker deployments on virtualized environments — standardized across retail operations in 100+ stores
• → Grafana implementation for real-time process monitoring and proactive incident detection
• → Critical incident resolution — restored production services and reduced recovery time for high-impact retail systems
• → Proposed microservices architecture improvement adopted by engineering leadership

Led the end-to-end digital transformation of a multi-unit lending and collections platform across 3 business units, managing a 12-person team (9 engineers, 2 QA, 1 DevOps). Architected and delivered event-driven systems on Kafka processing 400K monthly credit applications and a payments circuit handling 200M transactions — over 1B MXN processed in a single quarter. Designed state machines for credit origination, collections strategy, and decisioning, while building the full digital sales and collections infrastructure from the ground up.

• → 400K monthly credit applications — event-driven origination platform on Kafka with state machines deployed across 3 business units
• → 200M payment transactions — full payments circuit: Oxxo, PayNearMe, OpenPay, card payments, STP, bank direct debits (BBVA, Santander, HSBC)
• → 1B MXN processed in 3 months across digital payment channels
• → Collections decision engine: 1M batch jobs processed in 40 seconds using Spark + Python
• → Led 12-person engineering team — credit origination, payments, collections, and mobile sales app (Android, Kafka, Firebase)
• → Credit bureau (Buró de Crédito) integration for national lending operations
• → Employee of the Year — consecutive awards, youngest team member to receive the recognition
• → Platform remains in production and served as the architectural foundation for the next-generation lending system

Developed and implemented a web-based car rental system that optimized payment and booking workflows. Led the design and development of a real-time reservation system enabling dynamic pricing and availability management, ensuring an efficient and user-friendly experience.

• → Web-based car rental system with optimized payment workflows
• → Real-time reservation system with dynamic pricing
• → Full-stack development and team leadership
