October 2021 — Present

VerSe Innovation · Dailyhunt, Magzter and Josh

Senior Director of Engineering

Leads backend, platform, applied-AI, and data responsibilities across major consumer products, working through senior leaders and architects.

  • Partnered with the CFO on a company-wide cost mandate that cut Dailyhunt's monthly infrastructure spend by 49%, creating approximately ₹260 million in annualized savings without compromising scale or reliability.
  • Set the engineering agenda as Dailyhunt matured beyond 350 million MAU, shifting focus toward efficiency, recommendation quality, and new revenue initiatives including Dailyhunt Premium and a short-stories format for tier-one audiences.
  • Dailyhunt put classification, summarization, and notification-title generation into production: classification abstracts location relevance (state, city, national, international) and notification relevance from an immediate-push perspective, with Qdrant serving as the system of record and Elasticsearch retired from that path.
  • Dailyhunt sustained millisecond-class latency above 50,000 requests per second during elections, IPL, and notification spikes; introducing Go services and GraalVM native builds cut compute cost by more than 30%.
  • Set technical direction across Dailyhunt and Magzter - integrating Magzter's premium content into Dailyhunt Premium, modernizing Magzter's backend through shared libraries and observability standards, directing build-versus-buy decisions for subscription products, and securing CFO funding for developer AI tooling.
  • Built leadership depth by coaching managers and senior engineers into broader ownership, delegating critical platform charters, and establishing succession coverage to sustain execution through organizational change.

  • Guided ranking strategy and execution that increased time spent per user by 35% while holding click-through rate and retention steady.
  • Dailyhunt moved more than 40 services and data stores from private infrastructure to Google Cloud, improving reliability and capacity predictability.
  • Ran roughly three live feed experiments per week using multi-armed bandit testing, expanding ranking signals from four facets to approximately 200 and lifting automated test coverage from 35% to 75% within 12 months through static analysis, coverage baselines, and a merge gate.

        Operating principles

        The defaults I fall back on when priorities conflict.

        Put scale in product context

        Technical decisions should connect to product experience and business outcomes.

        Design for repeatability

        Build durable engineering practices through clear ownership, observability, repeatable reviews, and reusable platform capabilities.

        Influence across boundaries

        Use transparent data and shared context to align engineering, product, infrastructure, and business teams.

        Technology landscape

        Tools and platforms used hands-on, not just managed from a distance.

        Selected work

        Independent projects built outside of any employer.
