i build the systems products run on — ingestion paths for petabyte-scale telemetry, transactional cores that hold at 140k RPM, and the alerting engines layered on top. eleven years of it across security, payments, e-commerce, and healthcare, owned end to end: schema, throughput, deploy, on-call.

founding engineer · svadhyay

  • live in private beta with ~50 users. learning communities have formed on their own — investing, startups — whose members open it daily and say it is what they now revise with. ios and android apps are in store review.
  • parents who cannot read or speak kannada use it to teach their children the kannada syllabus — the product carries the language the parent does not have.
  • took a childhood friend's unfunded idea to production alone — UI/UX, mobile and web clients, go + python services, test suites, kubernetes infra, and alerting.
  • answers stay grounded in the student's own textbooks — RAG over pgvector across PDF / EPUB / DOCX, langgraph agents for tutoring, illustration, and worksheet evaluation, on a fully self-hosted model stack (qwen · BGE · whisper).

staff engineer · netskope

  • made petabyte-scale device telemetry queryable at low latency — built the kafka pipeline streaming metrics and events into elasticsearch, and modeled the high-cardinality time-series underneath it for fast ingest.
  • gave every product in the suite one way to alert on live telemetry — owned the rule-definition layer and the worker-based monitoring platform whose rule engine evaluates streaming telemetry and fans out multi-channel notifications.
  • restored login for locked-out enterprise accounts — ABC supply, electric boat, westbank — by eliminating a standing class of SAML / OIDC sync bugs across the IDP platform (~200 tenants · ~500 users each · long-tail of 10k).
  • onboarded netskope as a first-class IDP provider, so netskope-issued identities authenticate across the broader product suite.

backend & devops lead · explorex technologies

  • scaled the orders service behind digital dine-in to 140k RPM at 20:80 read/write, without third-party lock providers, by architecting the multi-service platform underneath it. it carried ~₹1 crore of GMV per day.
  • eliminated aggregated-view stock discrepancies by modeling inventory as an append-only ledger, leading 6 engineers through the rebuild. hired and mentored an SDE-3 from first interview to core contributor.
  • restored auto-settlement — a flagship capability that had been broken — and made reconciliation a default rather than a chore, by redesigning payments and payouts end-to-end. integrated axis bank and phonepe; phonepe shipped in one week.
  • ended cross-service schema drift org-wide and cut the time to stand up a new service, by building shared SDKs and a protobuf-based global schema store that every service adopted.
  • established the engineering SDLC, on-call rotation, and the product–engineering alignment that ended ambiguous requirements — on AWS infra and CI/CD (argo cd / rollouts / events) with prometheus, grafana, jaeger, and EFK behind it.

sde 3 · cashfree payments

  • ended credential-sharing between merchants and partners by building the partner platform on OAuth-based merchant impersonation (kong OAuth plugin); onboarded ~50 partners, with referral payouts driven by a vertical-specific commission calculator.
  • led the typescript → go migration of the partner platform, rewrote the 3-way reconciliation engine (PG recon) for extensibility and resilience, and authored the shared go libraries underneath both.

sde 2 → sde 3 · halodoc technologies

  • increased consultation discovery throughput 10× by rewriting the bintan consultations search on elasticsearch — fixing doctor-listing scoring and ranking that algolia could not model. it has run unchanged since, and replacing algolia cut search costs outright.
  • cut policy reconciliation time by more than half on the misool insurance platform, splitting benefits and claims into dedicated microservices and leading the 6 engineers who built them.
  • led the migration of consultation services from EC2 to kubernetes alongside the devops team.
  • built platform SDKs for distributed caching (redis · hazelcast · caffeine) and locking (zookeeper · redis-lock) behind provider-agnostic interfaces; drove SDE-1/2/3 interview panels and started the internal tech-talk series.
dec 2016 — jun 2018 · bengaluru

software development engineer · FICO (fair isaac india)

  • cut bug-fix turnaround across the FICO DMS suite by building a java agent that captured variable values at the moment of exception.
  • cut compliance report generation by about a week for the FICO-tonbeller AML and KYC products by designing their ETL + kibana reporting pipeline; contributed to the T-mobile credit-scoring dashboard built on the same products.
jan 2015 — dec 2016 · bengaluru

intern → member of technical staff · sprinklr

  • owned the content management automation suite used by mcdonald's, coca-cola, and other large brands; delivered coverage for the newly launched pinterest channel integration.
  • built an automation testing commons library to abstract cross-cutting test concerns.
