About

Professional summary

I am a full-stack engineer with over three years of production experience, transitioning my career focus toward DevOps and cloud infrastructure. I build, deploy, and operate reliable systems with an emphasis on automation, security, and operational readiness.

I have hands-on experience with AWS services including EC2, VPC, ECS Fargate, EKS, ECR, ALB, S3, CloudFront, Lambda, DynamoDB, ElastiCache, IAM, CloudWatch, SNS, and Secrets Manager. I use Terraform and Ansible to provision and configure repeatable infrastructure across staging and production environments.

I design CI/CD workflows using GitHub Actions and Jenkins, incorporating automated testing, security scanning, Docker image publishing, approval-based promotions, and rollback protections. I work with OIDC-based cloud authentication to avoid static credentials and improve deployment security.

I am experienced with Docker, Docker Compose, Kubernetes, Linux administration, Nginx reverse proxies, TLS configuration, and production deployment workflows. My monitoring and reliability toolkit includes Prometheus, Grafana, Loki, CloudWatch, Sentry, and LogRocket.

Alongside infrastructure work, I continue to build backend and full-stack systems with Node.js, Express, TypeScript, MongoDB, PostgreSQL, MySQL, Redis, and Next.js. I have supported fintech and billing platforms, delivered high-volume transaction features, and implemented caching, authentication, backups, health checks, autoscaling, and operational runbooks.

I am seeking DevOps and cloud infrastructure opportunities where I can apply my production engineering background to improve deployment safety, observability, scalability, and system reliability.

Experience

Career history

Full-Stack Engineer PriceEstimator.ai

I set up GitHub Actions CI/CD pipelines with linting, type-checking, and build gates for pull requests, plus tag-based staging-to-production promotion. I containerized the application through multi-stage Docker builds and maintained environment-specific Nginx reverse-proxy configurations.

I build and optimize Node.js and Express services for a production billing platform using MongoDB and Redis. My work includes database-load reduction through caching, JWT authentication, Zod-validated APIs, Microsoft Graph API single sign-on, and automated Microsoft 365 mailbox data ingestion.

I keep deployment configurations, environment variables, and operational documentation current across staging and production environments.

Software Engineer SmartCrowd

I monitored a fintech platform serving more than 10,000 active users using Sentry and LogRocket. I triaged alerts daily, investigated production issues, and helped drive incident resolution.

I led end-to-end delivery of the Share Transfer Facility for a high-volume transaction system, releasing it with zero major post-release production issues. I was promoted to Software Engineer in just over two years for leading architecture improvements and delivering fintech product features.
