Hi, I am Saurav Kothari, a full stack engineer with 6 years of experience building full stack systems as both an IC and a Lead. I consider myself to be an engineer first, developer second; i.e, my goal is to solve problems and technology is one of the tools I utilize to solve them.

Over the past years I have had the opportunity to work across a wide range of business domains from SaaS to e-commerce. I have worked across the stack over components that have been internal facing as well as user facing and I believe I can empathize with the end consumer of my product.

My experience as a Product Engineer has expanded my horizon to understand business goals and how to tie them to tech goals to create a win-win scenario for everyone involved. This involved launching a product from scratch, building a team from the ground up and guiding them to be self sufficient in their contributions.

I have been fortunate to have worked with various languages and frameworks and feel comfortable learning new ones as needed and switching between them on the go.

Product Engineer, May 2019 - Aug 2020
Domain: Logistics, Supply Chain, Warehousing, Accounts Payable, Financial Reconciliation
Technology: Kotlin, TypeScript, Dropwizard, ReactJS, Kubernetes, Azure SQL, Cosmos Db

As a Product Engineer, my responsibilities involved taking ownership of the business goals of the problem area, to build a roadmap for execution and achieving business goals via tech and non-tech solutions.

  1. First Party Procurement
  2. We were building a product that would systemize the procurement process of goods at Udaan. We were purchasing and selling a lot of inventory but all the accounting was done outside the system. The goal was to build first class workflows around purchases, inwarding and reconciliation. This would help identify leaks and gaps in the financial process and prevent any potential for abuse.

    The architecture would include a product master, location master, vendor master, the layer to raise purchase orders for products to vendors, the layer to match the goods received at the Warehouse against open POs and subsequently trigger the relevant financial workflow(s).

    This was a massive overhaul of processes around warehousing, ordering, pricing and accounting. Key stakeholders across each domain were consulted and agreement was reached to roll out pan-india in phases over 6 months. The first warehouse was launched and the process stabilised in 1 month, 7 more were launched over the course of 2 months. Pricing and Ordering workflows were rolled out 100% across two categories with the rest to be ramped up in quick succession.

    • Each location was mapped to kind of goods being bought/sold at location and had an approval matrix that would allow actions to be monitored and approved/rejected centrally
    • Allow financial documents (po, credit notes) to be generated and sent directly to vendors via email
    • Map purchase orders to vendor + location and only allow inwards of matching goods
    • Every inward is checked against open POs for the vendor and only allowed if there is matching line item
    • All deviations from the PO are recorded, staged in warehouse and require additional approval to be inwarded
    • Every inward cycle to trigger the relevant financial workflows including vendor payments, adjustment notes, return notes etc
