DevSecOps

Securing applications, infrastructure, and game pipelines — from cryptographic key management to anti-tamper systems.

Application Security

›

OWASP Top 10 threat modeling and secure code review across Web3 backends (Golang, Node.js) and game clients (C#, Unity)

›

Penetration testing methodology covering API endpoints, smart contracts, and client-side attack surface

›

SAST/DAST integration into CI/CD (Semgrep, Trivy, SonarQube) for automated vulnerability detection

›

Dependency scanning (Dependabot, Renovate) with automated PRs for critical CVEs

›

Secrets management (AWS Secrets Manager, Vault, GitHub Secrets) with rotation policies and access audit trails

Game Security

›

Anti-cheat and anti-tampering systems for multiplayer games (memory protection, integrity verification, speed-hack detection)

›

Reverse-engineering prevention: control flow obfuscation, string encryption, symbol stripping for Unity (Mono/IL2CPP) assemblies

›

Asset bundle protection: AES-256 encryption, HMAC signing, signed URL delivery with expiration policies

›

Client integrity: jailbreak/root detection, debugger detection, code hooking prevention, certificate pinning

›

Secure progression storage with server-authoritative state validation and anomaly detection

Cryptography & Key Management

›

Cryptographic key hierarchy design: hot/cold wallet separation, quorum-based signing for high-value transactions

›

Key storage: AWS KMS, Secrets Manager, hardware-backed keystores, envelope encryption patterns

›

HSM integration and software fallback with audited key rotation policies

›

Transaction security: pre-flight simulation, replay protection, rate-limited RPC endpoints with request signing

Cloud Security (AWS)

›

IAM: least-privilege policy design, permission boundaries, role-based access across multi-account organizations

›

Container security (ECS/EKS): security groups, pod security policies, encrypted task definitions, image scanning in ECR

›

Network security: VPC isolation, private subnets, security group micro-segmentation, NAT gateway architecture

›

Monitoring & compliance: CloudTrail, Config rules, GuardDuty, Security Hub, automated incident response

›

Infrastructure as Code security: Terraform state locking, policy-as-code (Sentinel/OPA), drift detection

CI/CD Security

›

Secure pipeline design: branch protection, required reviews, signed commits, gated approvals for production

›

Build-time security scanning: dependency vulnerabilities, secret leakage prevention, container image scanning

›

Artifact signing and provenance attestation for deployable artifacts

›

Deployment security: canary releases, rollback automation, post-deployment validation

Tools & Technologies

›

Static Analysis: Semgrep, SonarQube, Trivy, Checkov

›

Secrets: AWS Secrets Manager, HashiCorp Vault, GitHub Secrets

›
