Pablo Albaladejo — Senior Backend + AI Engineer

I build high-scale backend platforms and production-grade Generative AI systems (Agentic Workflows + LLM Ops). 15+ years across SaaS (B2B/B2C), including CTO / technical co-founder roles.

About

  • Current focus: bridging robust backend engineering and Generative AI (agent assistance, automation, and data-to-insight pipelines).
  • Strengths: event-driven / serverless architectures on AWS, platform reliability & cost efficiency, and pragmatic product execution.
  • Fun fact: triathlete (I like long runs—both in code and on the road).

Highlights

  • Scale: designing systems processing 1M+ daily call transcriptions with low-latency requirements for real-time agent assistance.
  • LLM Ops: production observability for quality/cost/performance (incl. Braintrust) + feedback loops for continuous improvement.
  • Cloud modernization: migrating legacy systems to event-driven, cloud-native architectures (AWS Lambda/Fargate/DynamoDB/CDK).
  • Product & leadership: 15+ years building SaaS in HealthTech, HR, and Telecoms; experience as CTO / technical co-founder.

What I work on

  • Agentic workflows: tool-using assistants, orchestration patterns, and backend primitives that make agents safe and useful.
  • RAG & data pipelines: turning raw conversation data into actionable insights, with strong guardrails and traceability.
  • Backend architecture: Hexagonal Architecture, event-driven systems, domain modeling, and pragmatic APIs.
  • Production engineering: observability, performance, reliability, cost controls, and CI/CD that teams can trust.

Tech (most used)

  • Languages: TypeScript/Node.js, Go, Python (and past experience with Java).
  • AWS: Lambda, Fargate, DynamoDB, API Gateway, EventBridge, CDK.
  • Architecture: Event-Driven Architecture, serverless, microservices, Hexagonal Architecture.
  • AI / LLM: Generative AI, Agentic Workflows, RAG, prompt engineering, evaluation & observability (Braintrust).
  • Tooling: Docker, Kubernetes, GitHub Actions, GitLab CI, Swagger/Postman.
