Work Experience

Independent Software Consultant — Full-Stack & Systems AutomationApr 2024 – Present
Client Advisory & Independent Engineering · Remote (Prayagraj, India)
  • FirstCron Services Pvt Ltd (Mar 2026 – Present): Architected SyntraFlow, an enterprise regression automation infrastructure for Oracle Fusion ERP deployed across 50+ business entities.
  • Engineered a three-tier execution engine (Chrome MV3 extension + desktop runner daemon + headless Playwright service) with self-healing DOM locators, cutting regression cycles by 40%.
  • SamMegh Technologies (Apr 2024 – Feb 2026): Diagnosed database execution bottlenecks and refactored Spring Boot query paths, reducing end-to-end API response latency from ~800ms to <300ms.
  • Architected Spring Boot API gateways with role-based access control (RBAC), multi-tenant persistence, and query optimization eliminating N+1 bottlenecks.
Software Engineer — Platform & Enterprise RetailNov 2021 – Mar 2024
Reflexis Systems (Zebra Technologies) · Pune, India
  • Engineered and scaled enterprise retail workforce management platforms serving 150K+ daily active store associates across 400+ locations under strict sub-100ms API SLAs.
  • Refactored monolithic legacy services into domain-bounded Spring Boot microservices with isolated DB2 persistence schemas and clean REST contracts.
  • Maintained high-availability retail store services; diagnosed memory bottlenecks, analyzed heap dumps, and tuned G1GC parameters to increase transaction throughput by 30% during retail peak surges.
  • Overhauled automated Jenkins CI/CD deployment pipelines, cutting production release cycles from bi-weekly to under 2 days.

Key Projects & Systems

PracharFlow ↗ — Lead Enterprise Microservice (Deterministic Skia Canvas)Java 21 · Spring Boot 3 · Skija (Skia) · PostgreSQL · Flyway · Telegram API
  • Designed a deterministic graphic rendering engine in Java 21 / Spring Boot 3 replacing generative diffusion models for vernacular regional typography (Devanagari/Gujarati).
  • Achieved 100% deterministic pixel-perfect output rendering in under 150ms per creative asset on raster surfaces with zero GPU infrastructure overhead.
Workflow Studio ↗ — Full-Stack Multi-Agent Orchestrator (Next.js + Node Engine)React, Next.js, TypeScript, Node.js, SQLite, Atlassian APIs
  • Engineered an autonomous task decomposition engine computing dependency-ordered DAGs using Kahn's topological sort and cycle detection.
  • Implemented distributed task leases with monotonic fencing tokens to reject stale writes and prevent split-brain state across concurrent agents.
  • Decoupled the dispatch engine into @workflow-studio/core with strict Node-only tsconfig boundaries, powering the Web UI, CLI runner, and TradeSense terminal.
DealDekho ↗ — E-Commerce Price Discovery PlatformNext.js 15, React, TypeScript, PostgreSQL, Redis, BullMQ
  • Architected multi-aggregator product search and price tracking paired with client-side telemetry from the ShopLens browser extension, normalizing price variance across marketplaces.
