Reliable software, reliable teams, reliable returns.
Practical systems for engineering leaders, software teams, and investors to scale without surprises, built from 25+ years in engineering, including 8+ at Amazon.
What I do
I lead transformations across cloud, SaaS, e-commerce, supply chain, and healthcare—improving reliability, developer velocity, compliance, and cost structure.
Who this blog is for
- Engineering leaders (EM → VP) who own reliability, velocity, and outcomes
- Software development teams seeking calm, predictable delivery at scale
- Investors & founders focused on de-risking execution and capital efficiency
What I write about
- Platform & Reliability: SLOs, observability, incident response, error budgets, capacity planning
- Execution Systems: quarterly planning, dependency & risk management, roadmap credibility, KPIs/OKRs
- People & Culture: hiring, coaching, performance systems, psychological safety that scales
- Security & Compliance: IAM/VPC guardrails, data residency, secure-by-default mechanisms in product teams
- Modernization & Migrations: strangler patterns, deprecations, idempotency, backfills, change management
- Leader Toolkits: runbooks, post-mortems, decision memos, review templates, checklists you can reuse
- Reliability Economics (Investor-grade): de-risking delivery, cost controls, margin-aware architecture
Expect opinionated, context-aware notes. I’ll show the trade-offs, share templates, and change my mind when better evidence wins.
