The line manager role is disappearing faster than you think

Mohit Ranka — Tue, 21 Jul 2026 10:00:00 +0530

The line manager role is disappearing faster than most career plans assume. Meta has already moved toward one senior manager for roughly every fifty developers. That is not a distant forecast. It is an operating choice already in the market. If you lead engineers — or want to — the useful question …

Near-real-time is a product promise, not a Kafka cluster

Mohit Ranka — Thu, 16 Jul 2026 10:00:00 +0530

“Near-real-time” is often used as a synonym for “we bought a streaming stack.” On GTM data platforms, that confusion is expensive. The product promise is about whether a decision-maker can trust a number in time — not whether an event log is busy. At LinkedIn, the Enterprise Data Platform (EDP) was …

The platform team’s real job is interfaces

Mohit Ranka — Thu, 13 Nov 2025 10:00:00 +0530

At LinkedIn, the Enterprise Data Platform (EDP) was meant to be the centralized way GTM teams managed and consumed datasets. On paper, that is a clear platform charter. In practice, a platform is only real when its interfaces get adopted — including by teams that already have a path that “works …

When I still choose a relational database

Mohit Ranka — Thu, 13 Mar 2025 10:00:00 +0530

In 2013 I wrote RDBMS vs. NOSQL? as a pushback against fashion. The fashion changed costumes — document stores, wide-column, NewSQL, "Postgres is fine," "everything in the lakehouse" — but the underlying mistake did not: picking a datastore from a blog post instead of from access patterns and failure modes.

A relational …

Freshness SLOs: the metric product teams actually feel

Mohit Ranka — Thu, 11 Jul 2024 10:00:00 +0530

API latency SLOs changed how we run services. GTM data work taught me the sibling idea the hard way: product teams do not experience your job-success chart. They experience a dashboard that is late, wrong, or disagrees with another “official” number. At LinkedIn, BI teams on Power BI and Tableau …

Saying no as a platform EM without becoming the villain

Mohit Ranka — Wed, 08 Nov 2023 10:00:00 +0530

Platform engineering managers do not run out of good ideas. They run out of capacity to say yes to every reasonable request without wrecking the shared system. The skill is not blunt refusal. It is no with a path — specific enough that partners can actually execute, firm enough that your …

Identity systems fail socially before they fail cryptographically

Mohit Ranka — Wed, 08 Mar 2023 10:00:00 +0530

When people talk about identity and SSO, they reach for algorithms: token lifetimes, key rotation, SAML vs OIDC, session fixation. Those details matter. In systems I have built and operated, the outages and near-misses that hurt most started earlier — as social and product failures wearing security clothing.

Identity systems often …

What “led the web launch” taught me about constraints

Mohit Ranka — Wed, 06 Jul 2022 10:00:00 +0530

At Postman, “put the product on the web” was not a greenfield rewrite. It was a constraint problem: a desktop-native API tool used by millions of developers, enterprise pressure for browser access, browser security that blocked the old execution model, and a conference date that would not move. I was …

Incubating 0→1 beside a mature product

Mohit Ranka — Tue, 15 Jun 2021 10:00:00 +0530

When I was at Postman, the core product was already the default API client for a huge HTTP/HTTPS world — on the order of tens of millions of developers on desktop. That success created a sharp problem: how do you explore what comes after HTTP without slowing the product everyone …

How I review a distributed design in 45 minutes

Mohit Ranka — Wed, 03 Mar 2021 10:00:00 +0530

The most expensive design reviews I have run were not missing a box on a diagram. They were missing a decision. One of them froze delivery on an EDP self-serve portal for about a month while two strong engineers disagreed in public about monolith versus microservices — and ownership quietly collapsed …

Introducing on-call without burning the team

Mohit Ranka — Tue, 10 Nov 2020 10:00:00 +0530

At Postman, my team owned a large-scale platform surface used by millions of developers. What we did not own — formally — was a predictable operational response. Production issues and public GitHub noise were handled ad hoc. Someone jumped in, or everyone hesitated. Retrospectives lacked a clear accountable role. The system worked …

GTM datasets need data contracts

Mohit Ranka — Wed, 01 Jul 2020 10:00:00 +0530

When a go-to-market dashboard is wrong, nobody says “the warehouse is eventually consistent.” They say the number is wrong — and they stop trusting the platform. On LinkedIn’s Enterprise Data Platform (EDP) work, the failure mode was rarely a missing chart type. It was informal truth: datasets without clear producers …

RDBMS vs. NOSQL?

Mohit Ranka — Sat, 29 Jun 2013 00:16:00 +0530

From our own experience designing and operating a highly available, highly scalable ecommerce platform, we have come to realize that relational databases should only be used when an application really needs the complex query, table join and transaction capabilities of a full-blown relational database. In all other cases, when such …
