Example engagements that illustrate how I work with teams on architecture, reliability, deployment, and operational readiness.
A B2B SaaS company with 40+ Lambda functions and growing AWS costs needed an external architecture review. The engagement produced a risk assessment, service boundary recommendations, and a phased migration roadmap that reduced cross-service coupling and cut Lambda cold starts by restructuring function packaging.
Scope: 2-week architecture audit
Focus areas: Lambda sprawl, service boundaries, cost optimization, deployment strategy
An engineering team building on EventBridge and SQS was experiencing message loss and duplicate processing in their order pipeline. The review identified missing dead-letter queues, absent idempotency checks, and unclear retry policies. Deliverables included a redesigned event flow, DLQ alerting setup, and idempotency implementation patterns.
Scope: 1-week focused review
Focus areas: Event-driven reliability, idempotency, dead-letter handling, observability
A platform team managing a serverless monorepo with 12 services had deploy times exceeding 45 minutes and frequent rollback failures. The engagement delivered a restructured CI/CD pipeline using selective deployment, improved Serverless Framework configuration, and a canary deployment strategy for high-risk services.
Scope: 2-week advisory engagement
Focus areas: CI/CD, monorepo deployment, rollback strategy, deploy time optimization
A startup preparing to onboard its first enterprise customer needed confidence that their serverless infrastructure could handle the load and meet SLA requirements. The review covered failure modes, observability gaps, IAM security posture, and incident response readiness, producing a prioritized remediation plan executed over 3 sprints.
Scope: 1-week production readiness review + 2-week follow-up advisory
Focus areas: Reliability, observability, security, incident readiness, SLA preparation
