CORE SYSTEM PRINCIPLES

Architectural Philosophies & Engineering Principles

01 // HEXAGONAL_CORE
Clean & Hexagonal Architecture

Strict boundary isolation between domain logic, relational storage, and delivery protocols. Infrastructure migrations never compromise business rules.

02 // CONCURRENCY_RUNTIME
First-Principles Concurrency & High Throughput

Non-blocking Go worker pools, lockless channels, and memory reuse via sync.Pool. Hardware resources saturate efficiently without garbage collection latency spikes.

03 // ZERO_TRUST_DEVSECOPS
Zero-Trust Security & Shift-Left AppSec

Continuous secret detection in CI/CD, cryptographic TOTP/HMAC authentication, and automated access governance audited under SOC 2 and Vanta baselines.

04 // DATA_PIPELINES_RESILIENCE
OLTP/OLAP Decoupling & Streaming Resilience

Shielding transactional checkout databases by routing heavy analytics, telemetry, and reporting directly into Snowflake and BigQuery via asynchronous pipelines.

AI ORCHESTRATION & AGENTIC SYSTEMS

Production AI Engineering & Deterministic Toolchains

Schema-First
Spec-Driven Dev (SDD)

Formal architectural specs, system invariants, and strict type contracts defined before generative execution loops to prevent drift.

Zero Hallucination
Continuous Evals & Guardrails

Continuous evaluation and adversarial testing with Promptfoo and Langfuse to eliminate hallucinations and regressions before production.

MCP / Workflows
Context Protocol & Multi-Agent DAGs

Hierarchical task decomposition into structured graphs and external tool execution via standard Model Context Protocol (MCP).

Crash-Resilient
Stateful Daemon Supervision

Long-running daemon supervision with resilient session checkpointing and automated crash recovery for autonomous coding workflows.

Senior Backend Engineer

@LATAM Airlines
Oct 2026 - Present
  • Designing and scaling distributed Go microservices on Google Cloud (GKE) governed by strict contract-first gRPC and Protocol Buffers schemas across web and mobile channels.
  • Architecting globally distributed persistence with strong consistency and ACID transactions on Google Cloud Spanner for passenger domain data across multi-country operations.
  • Building real-time Change Data Capture (CDC) and event-driven streaming pipelines with Apache Beam / Dataflow into BigQuery for immutable audit trails and historical modeling.
  • Engineering zero-downtime mass data migration and coexistence with transactional backends, applying continuous cross-system reconciliation and progressive canary rollouts with feature flags.
  • Embedding privacy governance (PII protection, automated data subject rights) and end-to-end operational resilience (SLIs/SLOs, load and chaos testing) directly into platform architecture.

Senior Software Engineer - Core Platform & Security

@Leal
Sep 2025 - Jun 2026
  • Engineered an enterprise real-time anti-fraud engine from scratch in Golang utilizing the Strategy Pattern to detect cashier collusion and rolling-window velocity anomalies, delivering sub-50ms synchronous endpoints into POS checkout with cross-timezone normalization.
  • Architected and deployed mission-critical microservices in Golang adopting Clean/Hexagonal Architecture and Go concurrency primitives (Goroutines, channels, worker pools) on DynamoDB and Redis, enabling non-blocking execution across high-volume transactional flows.
  • Centralized the core authentication platform into a unified OTP/TOTP microservice, enforcing strict rate limiting, transactional failover to relational storage, multi-channel billing calculation (SMS, WhatsApp, Email), and secure legal document attachments.
  • Decoupled analytical workloads from operational OLTP databases by integrating native gosnowflake drivers into Go microservices, aggregating millions of marketing interactions (sends, opens, clicks, ROI) into real-time merchant dashboards.
  • Spearheaded DevSecOps compliance and CVE remediation across 10+ core repositories under Vanta / SOC 2 standards, hardening Alpine production containers with dumb-init, migrating to modular AWS SDK v3, and engineering Rust contactability pipelines with zero-downtime Unleash feature flags.

Senior Backend Security Engineer

@Mercado Libre
Aug 2024 - Sep 2025
  • Architected and deployed an internal risk evaluation and access governance engine in Golang and Python, correlating BigQuery telemetry, internal REST APIs, and cloud storage to continuously audit permissions and trigger automated policy mitigation across the enterprise.
  • Engineered distributed scanning pipelines for continuous secret detection and PII data minimization across code repositories, commit histories, and Google Cloud storage buckets, proactively preventing credential exposure.
  • Instituted shift-left preventive security controls by embedding automated compliance checks into pre-commit hooks and CI/CD pipelines, proactively blocking hardcoded secrets and guaranteeing strict adherence to corporate security policies.
  • Automated security incident triage and response workflows by integrating n8n orchestration with Go microservices and Bash scripts, streamlining ticketing operations and significantly reducing operational response latency.
  • Enforced Zero-Trust architecture principles across cloud infrastructure, establishing continuous security posture monitoring and least-privilege identity access management (IAM) guardrails.

Software Engineer - Identity & Trust Platforms

@Imagemaker
Dec 2023 - Aug 2024
  • Architected digital identity verification and authorization microservices in Golang and PostgreSQL for enterprise trust platforms (SOVOS Trust-Services), preventing fraudulent onboarding and ensuring strict regulatory compliance.
  • Engineered multi-modal biometric and authentication pipelines, integrating facial recognition, automated challenge-response Q&A flows, and real-time validation against government databases.
  • Implemented enterprise-grade OAuth2 authentication protocols and resilient, multi-channel dynamic OTP verification microservices, ensuring high availability during peak verification traffic.
  • Optimized relational database queries and indexing in PostgreSQL, sustaining sub-second response times during concurrent enterprise onboarding sessions.
