Work Experience
Appian, Chennai Oct 2022 - Present
Senior Software Engineer Apr 2026 - Present
  • Evaluated multiple approaches for identifying the Latest Common Ancestor (LCA) across 5 distinct design-object types with heterogeneous underlying storage (K and RDBMS), and architected an extensible framework using SOLID principles, abstraction, the Strategy Design Pattern, and Spring Dependency Injection—decoupling object-specific logic to enable seamless extension to 20+ design-object types.
  • Designed and implemented a stop-button workflow for the Appian AI Copilot Dev Agent, enabling users to interrupt in-flight AI responses, safely terminate all ongoing tool operations, and return a clear interruption state confirming that execution has been stopped.
  • Optimized database sync performance by 90% resolving N+1 fetch problems in cross-database data synchronization.
  • Architected and led the development of a GenAI-powered ProcureSight SaaS platform, delivering semantic search and AI-generated vendor insights, generating $1M in Q1 revenue with $10M projected by EOP 2026.
  • Scaled search service capacity 4x (from 25 to 100 concurrent users), eliminating frequent >30 second timeouts and achieving stable performance of 200 requests/sec at 0.5 second latency.
Software Engineer II Oct 2022 - Mar 2026
  • Migrated Transaction Manager to Spring, reducing database connection usage by 50% across all environments, optimizing read/write traffic routing, and doubling system scalability validated by Locust load tests.
  • Led Avro Serializer integration and defined a Confluent Schema Evolution strategy for event consumers, enabling onboarding of three large beta customers processing 1800 events per minute.
  • Built a resilient, parallel-processing data ingestion orchestrator (SOLID design) that handles 36 daily jobs, ingesting ~20k records and 5k documents, with a real time monitoring dashboard ensuring data integrity and SOC2 compliance.
  • Automating the deployment process with GitLab Pipeline, ArgoCD, Liquibase, and SonarQube reduced deployment time by 75%, from 2hrs to just 30 mins, eliminating manual intervention.
  • Introduced an Episodic Memory approach for Vendor Award Summary generation (covering 1M vendors and 100M awards), which reduced LLM operational costs by 50% ($10K savings potential) and significantly simplified quarterly data reloads.
  • Accelerated Appian's multilingual app development by 90%+ with a new translation design object handling versioning, IA, IX, lozenge, compare and deploy.

Publicis Sapient, Bangalore Sep 2020 - Sep 2022
Associate Software Developer 1 & 2 Sep 2020 - Sep 2022
  • A Successful POC for a Global Experience Platform (GXP) supporting multiple Stellantis brand websites across APAC, the Middle East, and NA secured a $10M contract for product migration.
  • Eliminated weeks-long onboarding delays for new markets by integrating Model Compare and Financial Calculator pages with an extensible, no-code solution. Onboarded APAC and Middle East market in 2 days for validating, correcting the data.
  • Developed a utility to streamline data extraction from Product Catalog files (raw txt), and provided interface in AEM to address missing data. Reduced vehicle data generation time from a week to few minutes.
  • Boosted website traffic by 80% and sales by 50% within three months by integrating the Jeep APAC Build & Price configurator. Additionally, accelerated Middle East market onboarding to just 2 days by enhancing the configurator capabilities.
  • Automated advance booking process by eliminating manual intervention and processing time using PayU payments gateway and CarDekho.
