Data
Terraform · AWS · CloudFront · WAF · Route 53 · Auto Scaling · RDS
Production-grade multi-region setup across eu-central-1 and eu-north-1. Route 53 health-checked DNS failover, Auto Scaling groups behind ALBs in both regions, cross-region RDS read replicas, CloudFront with WAF (rate limiting, common rule sets), and static site delivery from S3 via OAI. Everything in Terraform with KMS encryption on all storage.
AWS services used: Route 53, CloudFront, WAF, ALB, Auto Scaling, EC2, RDS (cross-region replica), S3, KMS, ACM
Terraform · AWS · CloudTrail · Security Hub · IAM · KMS
Full security monitoring stack. IAM lockdown with enforced MFA, multi-region CloudTrail encrypted with KMS, CloudTrail Lake with 10 SQL-based threat hunting queries, Security Hub running CIS and FSBP benchmarks, CloudWatch-to-SNS alerting pipeline. Deployed on a real AWS account, ran attack simulations, and verified detections end to end.
AWS services used: IAM, STS, CloudTrail, CloudTrail Lake, Security Hub, CloudWatch, SNS, KMS, S3
Go · gRPC · Lexer/Parser · AWS SDK · Protocol Buffers
Custom IaC language with a full compiler pipeline (lexer, AST, semantic validation, code generation). AWS provider plugin handles VPC, EC2, and RDS provisioning. State management via .tbstate files. Published as a Homebrew tap with a VSCode syntax extension.
Go · Fiber · AWS Textract · Rekognition · Docker
Takes an ID photo and a selfie, runs Textract for document validation, then Rekognition face comparison at a 70% similarity threshold. Returns pass/fail with confidence scores. Deployed as a Docker container.
AWS services used: Textract, Rekognition
Terraform · AWS
Reusable module used across 3+ projects. VPC with multi-AZ public/private subnets, cost-effective NAT instances (not NAT Gateway), IMDSv2 enforcement, dynamic EC2 provisioning with per-instance security groups, encrypted EBS by default. Published to the Terraform registry.
AWS services used: VPC, EC2, EBS, IAM
Python · FastAPI · Docker Compose · PostgreSQL · Anthropic Claude API
Multi-session backend for browser-based task automation via Claude API. Async request handling, SSE streaming, stateless tool-proxy architecture for concurrent multi-user sessions.
