I design and ship cloud-native fintech & Web3 infrastructure: high-availability payments backends, AWS KMS–backed signers for EVM/Tron, and production CDK stacks on AWS.

• 🌏 Hong Kong / Singapore / Malaysia • 🕸️ mikeng.io
• 🔭 Currently building: Trustless (programmable card on Oasis Sapphire), ZKS – ZK Storage, and LookCard (crypto-collateralized debit/credit rails)
• 🎯 Interests: secure key management (HSM/KMS), PCI-ready architectures, ZK proofs in real systems, SRE/Platform reliability

AWS Serverless WordPress (CDK, Fargate, Aurora Serverless v2)
Highly scalable WordPress on AWS with CDN, EFS, Memcached, X-Ray.
Repo

AWS KMS Signer for Ethereum & Tron (TypeScript)
Use AWS KMS to sign EVM & Tron messages/transactions; no plaintext keys.
Repo • npm i aws-kms-signer-nodejs

AWS Parsec Gaming Rig (CloudFormation)
One-click GPU gaming/streaming rigs on AWS (G, G3, G4dn).
Repo

• Cloud: AWS (ECS Fargate/EC2, ALB/NLB, CloudFront, Route53, EFS, ElastiCache, RDS Aurora Serverless v2, Lambda, CDK, SSM, IAM, KMS)
• Backend: TypeScript/Node.js, Go (selective), Python; REST/GraphQL; event & queue design
• Security/Compliance: KMS/HSM patterns, key isolation, mTLS/TLS, authN/Z (NextAuth, FusionAuth), PCI-ready patterns
• Web3: EVM, Solidity, Oasis Sapphire (TEE), ZK proof flows, KMS-backed signers, bridging (LayerZero/Celer)
• SRE/Platform: observability (OpenTelemetry → Grafana/Tempo/Prom), GitHub Actions CI/CD, IaC (CDK/Terraform), cost/perf tuning

• Built CDK-based serverless WordPress architecture adopted/cloned by others (92★ / 43 forks and counting)
• Implemented AWS KMS signer for EVM/Tron to remove plaintext private keys from apps
• Designed GPU cloud rigs with cost guidance and launch templates (Parsec project)
