Backend & Cloud Systems Developer
I build production-ready APIs, cloud infrastructure, and automation systems with Python, FastAPI, and AWS. Backed by 20+ years in operations management - systems that run reliably, without babysitting.
Production Systems
Systems I've shipped to production with direct business impact
- Backend performance optimization - Reduced page load time from 5s to under 1s through query optimization, caching layer, and asset-level improvements.
- WordPress security recovery - Secured a compromised corporate site the same day. Implemented access control, security patches, WAF rules, and login hardening.
- Workflow automation - Automated manual reporting processes with scheduled jobs and structured data pipelines. Eliminated 3+ hours of weekly operational overhead.
- Production backend architecture (AWS) - Designed, built, and deployed a FastAPI + PostgreSQL backend on EC2 and RDS. Running with zero downtime since launch.
- Production-ready web & dashboard systems - Built and deployed web applications and internal dashboards focused on performance, SEO, and responsive UI.
- API & system integrations - Built n8n automation workflows integrating multiple APIs and internal systems. Repetitive manual operations fully eliminated.
Work Process
Clear process, transparent communication, and reliable delivery from day one.
01
Discovery Call
I align on your requirements, technical scope, and timeline - no assumptions, no guesswork.

What I Do
I design, build, and
ship systems to production.
I handle the entire end-to-end process - including backend, APIs, automation, and cloud deployment.
Cloud & Infrastructure
AWS environments that are documented and reproducible. EC2, S3, RDS, IAM, Docker. No black-box configs that only one person understands.

About
I build modern backend systems, cloud infrastructure, and automation workflows.
I'm a remote Backend & Cloud Developer focused on building scalable APIs, workflow automation, and production-ready systems using FastAPI, PostgreSQL, Docker, AWS, and n8n - with an emphasis on stability and low operational overhead.
20+ years managing live operations in aviation and tourism - I understand system reliability, real-world constraints, and what downtime actually costs.
No agencies, no middlemen. Direct communication, direct delivery.
