Carlos Lara Albir
Agentic Engineer
& Senior Backend Architect
Over 20 years designing resilient distributed architectures and high-concurrency systems that withstand real production load (Event-Driven with AWS SQS, SNS, and EventBridge, Node.js/TypeScript microservices, and mission-critical OTA synchronization). Today I multiply that track record with agentic AI: Claude Code in the terminal, custom MCP servers, and zero guesswork.
Core Strengths & Specialization
What I truly excel at after 20+ years in the backend trenches: resilient distributed systems, clean architecture, and exponential speed with AI.
Distributed & Event-Driven Architecture
Specialist in decoupling high-concurrency architectures using asynchronous messaging with AWS SQS, SNS, and EventBridge. Strict idempotency patterns, DLQ management, and fault tolerance ensuring zero event loss under extreme load spikes.
Mission-Critical Backend & Microservices
Designing, scaling, and modernizing legacy monolithic codebases into high-throughput microservices using TypeScript/Node.js and PHP. High-availability systems, real-time bi-directional synchronization with global travel leaders (OTAs), and PCI-DSS compliance.
Agentic AI Engineering & Tooling
Pioneering adoption of Claude Code, Antigravity, and custom Model Context Protocol (MCP) diagnostic servers. Strict Spec-Driven Development (SDD) and AI-augmented TDD: exponentially accelerating feature delivery while maintaining zero production reverts.
Data Modeling, Performance & BI
Deep data architecture across relational and NoSQL engines. Expert query tuning, index optimization, and aggregation pipelines on MongoDB and SQL Server, eliminating multi-gigabyte table scans, paired with Business Intelligence foundation from POSCRM.
Cool stuff I've built
High-impact projects: gnarly problems solved with clean architecture and resilient code.
Production MCP Diagnostic Server
Debugging multi-channel booking anomalies across 6 OTAs required manual multi-database log queries across gigabytes of data, consuming 15 to 60 minutes per incident.
Designed a dedicated Model Context Protocol (MCP) server with hexagonal architecture, granting AI assistants read-only access to MongoDB and SQL Server to reconstruct timelines automatically via natural language.
Availability Period Fixer
Detecting discrepancies between configured availability seasons and actual property bookings required manual data cross-referencing, causing slow investigations and diagnostic errors.
Built an internal tool that visualizes availability seasons and live bookings on an interactive graphic timeline, detects inconsistencies, and generates an automated repair proposal.
Real-time OTA Inventory Synchronization Engine
Preventing overbooking and rate desynchronization across millions of daily transactions with Booking.com, Airbnb, Expedia, and Vrbo.
Architected a highly resilient event-driven distributed system (EDA): TypeScript/Node.js microservices, asynchronous decoupling with AWS SQS queues and fan-out via SNS, strict idempotency handling, DLQ management, and PCI-DSS compliance.
High-Throughput Asynchronous E-Commerce Ingestion
Integrating heterogeneous real-time transactional feeds, clickstream data, inventory levels, and marketing telemetry at massive scale.
Decoupled asynchronous messaging topology using AWS SNS (fan-out) and SQS queues, paired with ultra-fast caching layers with Redis.
Personal Projects Orchestrated with AI
Hardware, embedded systems, local Edge AI, and native applications supercharged by autonomous AI agents (Claude, Gemma, and tailored prompts).
AgroAI — On-Device AI Agricultural Assistant
Delivering generative AI directly into the agricultural field where mobile signal is scarce or zero, with complete privacy and zero cloud dependencies.
Native Android app in Kotlin running Google's Gemma LLM locally on-device (Edge AI) to plan treatments, irrigation, and crop health 100% offline.
Hyundai / Kia Gen5W — Navigation Firmware RE
Investigating closed proprietary software in Hyundai/Kia Gen5W automotive navigation head units (SoC 'mango', European variant).
Reverse engineering multi-gigabyte firmware images orchestrated with AI assistants: squashfs/ext4 partition breakdown, magic bytes identification, unpacking scripts, and architectural docs with CLAUDE.md.
Ámbar — Touchscreen HiFi Media Launcher
Controlling audiophile playback (FLAC, MP3, streaming) on an ultra-wide secondary touchscreen (1920x720) without desktop UI friction.
Python/Flask kiosk app integrating Kodi (JSON-RPC) and Spotify (local SMTC + Web API) wrapped in a vintage VFD/amber UI with pywebview.
Career & Battles
Over two decades in the backend trenches: from bare-metal servers to event-driven microservices and agentic AI.
Senior Backend Developer & Connectivity Tech Reference
- Technical reference for Connectivity: deep domain and real-time PMS synchronization across the industry's leading holiday rental portals in order of expertise: Booking.com, Airbnb, VRBO, Expedia, Homes & Villas by Marriott, Feratel, and Google.
- Lead for Distributed & Event-Driven Architecture: designed decoupled asynchronous workflows using AWS SQS, SNS, and EventBridge, ensuring fault tolerance, strict idempotency, DLQs, and zero message loss under extreme traffic spikes.
- Built the entire backend for the internal Operations (OPS) platform used daily by 27+ teammates in support and account management.
- Full epic ownership without hand-holding: scoping with Product, designing the architecture, estimating, coding, and verifying in production.
- Championed and led AI-augmented engineering adoption across the team: Claude Code in terminal, custom MCP servers, SDD methodology, and productivity automations (including automated daily time-tracking correlating Jira, Google Calendar, and GitHub commits/PRs).
Backend Programmer Analyst & Business Intelligence
- Core development of the POSCRM platform: my launchpad into Business Intelligence (BI), analytical data modeling, and turning raw data into actionable business insight.
- Engineered complex SQL aggregations, stored procedures, and query tuning—establishing the analytical foundation I leverage today in operational data analytics and AI-driven diagnostics.
Founder & Full-Stack Engineer (360° Solutions)
- Engineered a bespoke PLM (Product Lifecycle Management) system from scratch for an automotive upholstery manufacturer supplying the Ford vehicle assembly plant in Almussafes: handling industrial traceability, bill of materials (BOM), and rigorous quality control.
- Founder wearing every single hat: corporate client relations, requirements elicitation, commercial budgeting, and end-to-end business operations.
- End-to-end full-stack execution: client-server systems architecture, backend APIs, frontend UI, relational database modeling, server deployment, and continuous technical support.
Backend & Cloud Systems Analyst
- Designed REST APIs for mobile applications and managed cloud infrastructure on AWS.
Early Engineering & Systems Administration
- Servicios Taurinos Serolo (2006–2009): Real-time online ticket sales and automated electronic turnstile access control on Microsoft SQL Server across major Spanish venues (Valencia, Albacete, El Puerto), sustaining sub-second reliability during massive box-office rushes.
