Systems that don't topple under 10×.
Architecture, delivery, and developer-facing GTM — the boring parts that make your product fly.
I'm Mayank Sanghvi — a senior systems architect who also publishes essays and video breakdowns to 650K+ technical minds a month. Fractional CTO, architecture audits, and sponsored deep-dives for dev-tool & cloud brands.

Senior architect who also writes & ships in public.
Most consultants either don't build or don't publish. I do both — every week. That means the recommendations you get are already road-tested against 650,000+ readers, engineers, and founders who dissect them publicly.
Postgres, Kafka, Redis, edge runtimes — I know where the dragons live because I’ve fought them.
Dev-tools hate being sold — they love being explained. I write the explanation buyers actually read.
Between hires, after a re-org, or during a launch window — I slot in cleanly without the org thrash.
Most clients stay 3–9 months. The first two weeks tell you everything; we keep it honest.
Three ways we can work together.
All engagements are remote, scoped in writing, and cancelable after 30 days with no penalty. Bespoke pricing per project scope.
