Engineering Specialization

Four tightly integrated disciplines built for production stability.

01 • WORKFLOW ORCHESTRATION
n8n Self-Hosted

Automated Event Pipelines

Design and maintenance of complex multi-branch DAGs, webhook ingestion, HMAC validation, automated retries with exponential backoff, and stateful CRM/ERP synchronization.

Architecture Pattern: Idempotent Webhook Consumer
Error Handling: DLQ + Instant Alerting
n8n Webhooks REST APIs Docker
02 • BACKEND
Go / Java 21

High-Throughput APIs

Microservices built with Go goroutines and Spring Boot 3 virtual threads for sub-millisecond data processing under high load.

Thread Pool: Non-blocking
Caching: Redis Distributed
03 • ERP OPS
Python / py3o

Odoo ERP Architecture

Custom business logic modules, procurement workflows, dynamic ODT/PDF templating, and bi-directional external API syncing.

Doc Engine: py3o dynamic
Integrations: XML-RPC & REST
04 • CLOUD & DEVOPS

Zero-Trust Linux VPS & Automated Deployments

Staging environments locked behind private Tailscale WireGuard mesh, Nginx reverse proxy with SSL termination, UFW firewall restrictions, and automated Docker rollouts with zero public administrative exposure.

SSH / Management: Tailscale Only (No 22 Open)
Container Runtime: Docker Compose & Networks
TLS Encryption: Automated Certbot Let's Encrypt
