Experience— 4 yrs and counting
  • Full Stack Engineer @ Scimplify — Bangalore, IN (Dec 2023 — Present)
    • Designed and built an Electronic Lab Notebook (ELN) from scratch for R&D chemists — a stage-gated Feasibility → Optimization → Validation batch workflow with golden-batch lineage, QC automation, and sample dispatch — now used daily by 20+ chemists in the Hyderabad lab, processing 343+ batches to date.
    • Shipped the ELN backend as an ~1.5k-line FastAPI service with 11 REST APIs and 5 MSSQL tables (stages, batches, QC, documents, dispatch), automating QC pass/fail evaluation against project requirement parameters.
    • Built and maintained a FastAPI backend spanning catalog, manufacturer, order, and marketing modules, deployed across dev/stage/prod environments with role-based access control.
    • Designed product and manufacturer search on MongoDB and Elasticsearch/OpenSearch with location-based filtering and category/industry taxonomy.
    • Built PubChem-based chemical enrichment pipelines (SMILES, InChI, GHS, molecular weight) with bulk CSV/CAS upload and background job processing.
    • Hardened production APIs with rate limiting, honeypot anti-crawler middleware, activity/security logging, and Docker + Jenkins CI/CD for GCP Cloud Run deployments.
