SSE @ Serko / Product Platform Engineering / Indie Game Dev

About

A generalist engineer with deep backend experience and a strong interest in game programming. Professionally, I work on distributed backend systems & creatively I explore game tech and simulations. Currently I'm working at Serko, where I'm part of platform engineering team. I’ve also led and coordinated teams of game developers and artists on multiple indie projects under the label "Bugless Bytes", owning technical direction and driving development from ideas to shipped releases (including a few failures). This has been a long running pursuit that began during my school years and has continued alongside my engineering career. I publish indie games under the label Bugless Bytes (buglessbytes.itch.io). Currently building > conquesta.io [Multiplayer RTS browser based game]

Cloud & Platform Modernization: Driving contributions to platform modernization, operational ownership transitions, and cloud-native infrastructure workflows across Kubernetes and Azure Kubernetes Service (AKS) environments. 3. Data Engineering & Migration: Contributing to large-scale production data migration initiatives, gaining hands-on experience with modern data engineering and medallion architecture patterns while designing reliable approaches for migrating data between live production applications with different database technologies. Working extensively with Azure Data Factory, dbt, NRQL (New Relic Query Language), and data engineering workflows at scale. 4. AI-Assisted Engineering: Building POCs for an AI-assisted OpenAPI mapping and code-generation orchestration workflow, leveraging LLMs and an LLM-as-a-Judge design pattern to evaluate mapping accuracy and generated code quality, with a focus on automating and accelerating API integration workflows.

Software Engineer 2 at 7-Eleven Global Solution Center – India, Aug 2024 - Nov 2025 · 1 yr 4 mos, Bengaluru, Key Contribution: Involved in the design & development efforts for a scalable backend layer for a Master Data Project, being developed from scratch in-house where I've: 1. Contributed to development of initial POC for Data Ingestion flow and optimization by reducing ingestion time by ~95% (from ~15minute to less than 30 seconds for 50K records) for data based on complex business rules & also participated in design discussions for a production grade implementation of DI pipeline for supporting ingestion at scale. 2. Contributed to architecture design & development of business critical features, involving granting exclusive ownership of resources to users for limited time, and ensuring information is broadcasted in realtime to all live users over a websocket connection. 3. Contributed to design and development of event-driven & scalable data ingestion flow involving complex business rules, to manage periodic ingestion of data in the database, as well as ensuring data availability and consistency for the other external systems that consumes the data and any associated changes for the same. 4. Designed and implemented an authorization system for a hierarchical data model, enabling admins to grant permissions at multiple levels of granularity across the feature set. Built support for wildcards and efficient tree-traversal algorithms to evaluate access quickly and reliably. Key Tech: NodeJS, AWS , PostgreSQL , MongoDB, Kafka 19-Aug-2024 - 14-Nov-2025

Software Engineer at Falabella India, Jun 2022 - Aug 2024 · 2 yrs 3 mos, Bengaluru, Contribution: 1.
