Consulting

I help engineering teams modernize platform architecture, improve reliability, and accelerate delivery - across cloud-native backend systems, DevOps pipelines, and blockchain-native products.

Who I help

Services

Platform modernization

Monolith decomposition, service boundaries, API compatibility, and incremental migration strategies.

  • Clear migration roadmap with preserved external contracts
  • Reduced coupling and faster release cycles
  • GitOps-ready deployment pipelines

Distributed systems & workflows

Event-driven architecture, Kafka pipelines, Camunda BPMN orchestration, and high-throughput transaction systems.

  • Reliable async processing at scale
  • Workflow test automation with BDD patterns
  • Performance improvements on critical paths

Reliability & observability

Datadog consolidation, actionable alerting, incident automation, and production support efficiency.

  • Reduced alert noise and faster triage
  • Standardized monitor and incident routing
  • Improved on-call experience for engineering teams

Technical leadership

Team hiring, mentoring, architecture governance, and delivery execution for platform engineering teams.

  • Stronger engineering culture and standards
  • Better cross-functional collaboration
  • Predictable delivery on complex initiatives

Blockchain & Web3 engineering

End-to-end blockchain product engineering from wallets and smart contracts to DeFi, chain integration, and production node infrastructure.

  • Secure wallet and custody architecture with operational guardrails
  • Smart contract and protocol design with audit-ready patterns
  • Cross-chain, DEX, and DeFi systems built for throughput and reliability
  • Indexer, validator, and node ops aligned with production SLOs

Cloud, DevOps & security

Production cloud architecture, container platforms, DevOps automation, and applied cryptography for secure, scalable systems.

  • AWS-first designs with portable patterns for GCP and Azure
  • Container and serverless platforms ready for production traffic
  • IaC-driven environments with stronger IAM and encryption posture
  • Cryptographic foundations for custody, signing, and data protection

Blockchain expertise

Hands-on experience across wallet platforms, DeFi, cross-chain infrastructure, and chain ops - from architecture through production delivery.

Capabilities

  • Wallet development (custody, hot/cold storage, HSM, multi-sig)
  • Smart contract development and security review
  • Chain integration and cross-chain messaging
  • DEX and DeFi protocol engineering
  • Blockchain indexing and event-driven pipelines
  • Node, validator, and chain infrastructure management
  • Bridge and forwarder architecture at production scale
  • BaaS platform design (Ethereum, Hyperledger Fabric, multi-cloud)

Cloud & DevOps expertise

Production cloud architecture and DevOps delivery across AWS, Google Cloud, and Azure - from networking and containers to data, ML, and secure operations.

Capabilities

  • Container orchestration with ECS, EKS, and Fargate
  • Serverless and event-driven architecture with Lambda and API Gateway
  • Load balancing, VPC design, and secure network segmentation
  • IAM policies, KMS encryption, and secrets management
  • GitOps, CI/CD, and infrastructure-as-code (Terraform, GitHub Actions)
  • Managed data and messaging: RDS, DynamoDB, S3, ElastiCache, MSK
  • ML platform setup and operationalization with SageMaker
  • Confidential computing patterns with AWS Nitro Enclaves
  • Multi-cloud delivery on Google Cloud and Azure equivalents

Cloud platforms

AWSGoogle CloudAzure

Hands-on with equivalent services on Google Cloud and Azure for compute, storage, networking, identity, and managed data platforms.

Cryptography expertise

Applied cryptography for secure systems - from wallet custody and key management to integrity, signing, and encryption at scale.

  • Digital signature algorithms for authentication and non-repudiation
  • Asymmetric cryptography (RSA, ECC, key exchange, PKI)
  • Symmetric cryptography (AES, key derivation, envelope encryption)
  • Hashing algorithms (SHA-256, SHA-3, HMAC) and integrity verification
  • Applied in wallet custody, HSM integrations, and secure key management

Engagement models

Architecture review

Focused assessment of platform architecture, deployment model, and operational readiness with actionable recommendations.

Delivery leadership

Embedded technical leadership for high-stakes migrations, platform builds, or reliability initiatives over 3-6 months.

Advisory

Ongoing strategic guidance on team structure, engineering practices, and technology choices.
