Hi There! 👋I'm Muru

Full Stack Engineer

I build B2B SaaS for regulated industries, using TypeScript end-to-end and event-driven services on AWS. As the founding engineer on HyperStart CLM, I scaled it from 0 to $300k ARR, and I now lead pharmacy automation with LLMs at MedMe Health.

Experiences

4 yrs 3 mos of experience across 2 companies

    MedMe Health

    December 2025 – Present · 11 mos · Toronto (remote)

    1. SWE 2

      Leading design of the fax-to-entry platform that automates pharmacy admin work at MedMe Health (YC W21).

      3 highlights
      • Led development of an LLM-based extractor that turns unstructured patient questionnaire answers into structured medication data. Working through its long tail of edge cases lifted fax-to-entry accuracy from ~60-65% to 95%+.
      • Drove HIPAA compliance: access-logged S3 buckets, PHI/PII scrubbing from logs, and server-side encryption of data at rest.
      • Made every service debuggable from one Grafana view, with vendor-agnostic OpenTelemetry traces and metrics across the platform.
  2. HyperVerge logo

    August 2022 – December 2025 · 3 yrs 5 mos · Bangalore (onsite)

    1. SDE 2

      April 2025 – December 2025 · 9 mos

      Owned core platform architecture for HyperStart, the company's contract lifecycle management (CLM) product.

      4 highlights
      • Cut infrastructure spend to a 10% MRR-to-server-cost ratio by profiling usage and reallocating resources over 3 months.
      • Built the event-driven job system on AWS SQS and EventBridge that runs all of the platform's async and scheduled work.
      • Led the architecture for CRM integrations (Salesforce, HubSpot) that prefill deal data to speed up the client deal-closure pipeline.
      • Mentored junior engineers and introduced a standard code-review process to raise code quality.
    2. SDE 1

      July 2023 – March 2025 · 1 yr 9 mos

      Founding engineer on HyperStart CLM, owning features from design through to customer outcome as the product scaled to $300k ARR.

      6 highlights
      • Architected an LLM-based pipeline that extracts metadata from signed contracts, one of the product's main selling points.
      • Cut contract-listing latency to under 5 seconds across 15,000+ records by restructuring responses and tuning queries.
      • Led VAPT and static code analysis for SOC 2 compliance, hardening API Gateways and Auto Scaling Groups.
      • Built an end-to-end testing pipeline in GitLab CI with Playwright and Docker that gates deployments.
      • Benchmarked an open-source PDF converter, then designed and deployed it as a production microservice.
      • Built a config-driven UI for stamp-paper procurement, so adding a new Article code is a single JSON change.
    3. SDE Intern

      August 2022 – June 2023 · 11 mos

      Built core ingestion and access-control foundations for the CLM platform.

      2 highlights
      • Built a Role-Based Access Control (RBAC) system, with database schemas and APIs that manage resource access through user groups.
      • Built Google Drive and OneDrive integrations that ingest PDFs for the AI extraction workflows.
  3. Samsung R&D Institute India logo

    Samsung R&D Institute India

    December 2021 – August 2022 · 9 mos · Part-time · Bangalore (remote)

    1. R&D Intern

      Applied machine learning to anomaly detection for security use cases.

      2 highlights
      • Built an unsupervised Isolation Forest model that detects anomalous user activity from IP, API URL, and MAC-address signals, an approach that also applies to fraud detection.
      • Generated synthetic training datasets and deployed the inference endpoint with Python/Django on Heroku.
