Software architecture, taught and built.

01 — Training

Workshops delivered

Ten years of building production systems, translated into programs that can be taught. Every workshop integrates theory and practice, with a deliverable lab per session and a capstone project at the close.

  Web application development with Spring Boot

  Five days · Eight modules and a bonus

  A REST API with Spring Boot 4 on Java 21, from container to deployment. The domain is not a toy: it is built on PEI, the integrative project evaluation platform, whose event has an eight-phase lifecycle — the same one used by science and entrepreneurship fairs.

  Modules

  1. 01Introduction and workshop objectives
  2. 02Containers, Compose and devcontainers
  3. 03Spring ecosystem fundamentals — IoC and DI in depth
  4. 04Web and REST — the request cycle, Jackson, the pattern underneath
  5. 05Persistence — JPA, Hibernate and Spring Data: who is who
  6. 06Security — OAuth2, your API as a Resource Server
  7. 07Images and deployment — layers, Dockerfile, RUN vs CMD vs ENTRYPOINT
  8. 08Microservices — Conway's Law, modular monolith, the eight fallacies
  9. 09Bonus — browser application and the role matrix

  Stack

  • Spring Boot 4
  • Java 21
  • PostgreSQL
  • Docker Compose
  • Devcontainers
  • OAuth2
  • OpenTelemetry
  • Grafana Tempo

  Nobody installs Java or Maven: they live inside the container. Each day has a start and an end branch, so anyone who gets stuck can keep going. Slides are written in Marp and delivered as PDF.

  Serverless architecture and voice computing with Alexa

  Five modules · Capstone project

  Voice interface design and real serverless architecture. How a user who speaks thinks differently from one who looks at a screen, and what building on ephemeral functions actually implies: cold starts, timeouts, secrets out of the code.

  Modules

  1. 01Voice computing fundamentals — VUI, intents, utterances and slots
  2. 02Serverless architecture with AWS Lambda — lifecycle and handlers
  3. 03Consuming public APIs from Alexa — caching, retries, circuit breaker
  4. 04Private APIs and security — Account Linking, OAuth 2.0, Secrets Manager
  5. 05Persistence and integration — DynamoDB, CloudWatch, APL and publishing

  Stack

  • Alexa Skills Kit
  • AWS Lambda
  • Node.js
  • DynamoDB
  • CloudWatch
  • OAuth 2.0

  The capstone integrates the Skill with the UTXJ science fair system (PEI): querying projects, categories and schedules by voice.

Programs adapt to the curriculum and the level of the group. They can run as an intensive workshop, a semester course, or ongoing mentorship, and new ones are designed around the specific need of the institution.

Where I have built

Technical architect at Tech Mahindra since 2022. The banking, media, and publishing projects are client engagements through that firm: systems where failure is measured in money or in credibility.

   Client engagement via Tech Mahindra

   Cross-team architect across developer tooling and fraud prevention. Designed the end-to-end fraud detection flow with real-time alerts, ACID integrity, and sub-second latency at peak volume.

2. Apr 2022 — Oct 2023

   Dow Jones Virginia and New York, USA

   Java Technical Architect · Framework Creator

   Client engagement via Tech Mahindra

   Designed a configuration-driven backend framework adopted across multiple squads. Real-time analytics platform processing over 2 million events per hour. Promoted to architect on the strength of that integration.

   Tech Mahindra Mexico City

   Technical Architect

   The firm I contract through. Alongside architecture on client engagements, I lead onboarding programs for international teams, pair programming sessions, and architecture deep-dives. This is where the teaching side of my work formally began.
