Cloud architecture, CI/CD automation, and production-grade deployment systems
DevOps & Infrastructure
Overview
Beyond application development, I take ownership of production systems, ensuring applications are deployed reliably, monitored proactively, and secured properly.
Across 11+ shipped applications in healthcare and research, I've operated production deployments on AWS EC2, Heroku, Azure (Docker), and Cloudflare Pages, with manual SSH/zip release pipelines, GitLab CI auto-deploys, and signed App Store + Google Play submissions. In healthcare research environments where uptime, data integrity, and compliance are critical, I've designed infrastructure that supports high availability, secure deployments, and continuous delivery.
I approach DevOps as a reliability discipline, not just deployment automation.
That work includes production outage response, uptime monitoring, DNS and domain management, Cloudflare configuration, server and database setup, security patching, release readiness, and ongoing remediation across internal and client-facing systems.
In production
- Multi-platform deployment portfolio: apps live on AWS EC2 (Rails monoliths with Nginx + Puma + systemd), Cloudflare Pages (Create React App PWAs and Vite SPAs), Heroku (auto-deployed staging environments + small- team production sites), and Azure (Docker containers for headless Ruby pipelines). App Store and Google Play submissions for React Native apps, with signed Android keystores and Apple bundles.
- GitLab CI pipelines: multi-stage validation across lint (RuboCop / Biome / scss-lint / haml-lint), security scans (Brakeman, GitLab secret- detection, license_finder, package-audit), and full RSpec / Minitest test suites with Selenium-driven system tests against headless Chrome service containers.
- Operational hardening: Active Record encryption (mixed deterministic
/ non-deterministic by field for query-aware PII),
valid_email_2MX- record validation on admin email,lockbox+blind_indexfor chat content and admin identity at rest, full Devise stack (lockable + timeoutable + invitable + confirmable) on admin auth, JWT rotation with transparent refresh on mobile clients, and jailbreak / root detection with periodic re-checks. - Maintenance discipline:
package-audit-driven bi-monthly patch rounds with structuredMAINTENANCE.mdbefore/after audit logs that document CVE severity, outdated/deprecated counts, and remediation rationale per round. A client-facing transparency artifact unusual for small-team Rails apps. - Operational ownership: ongoing production support across internal and client systems, including outage investigation, uptime checks, DNS and domain changes, Cloudflare configuration, server/database setup, deployment support, and post-launch remediation.
Problems Solved with DevOps & Infrastructure
1. Reliable CI/CD & Deployment Automation
Manual deployments introduce risk. I implemented CI/CD pipelines that:
- Automate build, test, and deployment workflows
- Enforce branch-based Git strategies
- Reduce human error during releases
- Enable zero-downtime deployment strategies
- Support staging and production parity
This significantly improved release confidence and deployment speed.
2. Scalable Cloud Infrastructure
I managed and architected cloud infrastructure using:
- AWS EC2 for application hosting
- RDS for managed relational databases
- S3 for file storage and backups
- IAM for secure access control
- Docker for containerized environments
- Heroku for streamlined PaaS deployments
Infrastructure was designed for scalability, redundancy, and cost efficiency.
3. Database Reliability & Data Protection
For research platforms handling critical data, I implemented:
- Automated database backups
- Disaster recovery planning
- Read replicas for high-read workloads
- Query performance optimization
- Secure access control policies
Ensuring long-term data integrity and minimizing downtime risks.
4. Monitoring & Observability
Proactive monitoring prevents costly downtime. I set up:
- Application performance monitoring
- Server health monitoring
- Log aggregation and analysis
- Alerting systems for failure detection
- Uptime monitoring services
This enabled early issue detection and faster incident resolution.
5. Security & Compliance
In healthcare environments, infrastructure must meet strict standards. I implemented:
- SSL/TLS certificate management
- Secure server configuration (Nginx/Apache hardening)
- Firewall and network access rules
- Secure credential management
- Environment isolation
- Backup encryption strategies
Supporting HIPAA-conscious development practices and secure data handling.
6. DNS, Domains & Multi-Environment Management
I managed domain and DNS configurations across providers, including:
- Cloudflare
- GoDaddy
- AWS Route 53
- Pantheon-managed environments
Ensuring stable domain routing, SSL enforcement, and proper staging-to- production transitions.
This also includes domain audits, renewal and expiry tracking, transfers, nameserver changes, SSL/TLS setup, and keeping production traffic routed correctly during launches and maintenance windows.
7. Documentation & Operational Readiness
Reliable systems require clear operational processes. I created:
- Deployment documentation
- Incident response runbooks
- Infrastructure diagrams
- Environment setup guides
- QA and release-readiness checklists
Reducing onboarding friction and improving system resilience.
Why DevOps Matters
Strong infrastructure practices enable:
- Faster, safer deployments
- Higher system reliability
- Better security posture
- Improved developer productivity
- Reduced operational risk
For production systems serving real users (especially in healthcare), DevOps is not optional. It is foundational.
