Experience
Full-Stack Engineer — Markets Post-Trade | Barclays Bank Plc, PuneCurrent
- Configuration Server (Java Spring Boot, greenfield): Designed and built a multi-tenant UI configuration microservice from scratch — application owners define toolbar, AG Grid, and stepper form configs through an admin UI; configs persist to SQL Server with full versioning, rollback, and editor audit trail. Deployed on OpenShift via GitLab CI/CD.
- Recursive Nested Config Engine: Engineered a self-referential config resolution model where each record carries component type, render metadata, field validations, and a chain pointer to the next nested config — enabling zero-redeployment UI changes across all downstream trading applications.
- React Component Library (active contributor): Contributing to the internal Shadcn + AG Grid component library used across Barclays Markets Post-Trade — custom grid wrappers, stepper forms, and toolbar builders consumed by multiple live trading applications.
- Cards & Loans Platform (112K+ customers, €26.9M+ payments): Led React/Zustand frontend revamp on AWS ECS, improving LCP/FCP by 30%. Scaled backend test coverage to 80%+ (JUnit, Mockito) and UI to 90%+ (Jest, Karma). Reduced sprint cycle time by 25% through reusable component libraries and standardised API contracts.
- Design System & Accessibility: Built standardised, accessible design-system components (CSS, Storybook, responsive layouts), reducing UI defects by 40%, improving responsiveness by 60%, and accelerating feature roll-out speed by 20–30%.
- Headless CMS Migration: Transformed Adobe AEM-managed content into reusable React Native components, reducing rewriting overhead by 80% and significantly improving long-term maintainability.
- API Analytics Pipeline: Engineered a Jenkins + Node.js pipeline replacing manual reporting with dynamic Chart.js dashboards for real-time API performance insights — reducing manual intervention by 100%.

- Visual No-Code Builder Suite (Next.js + NestJS + MongoDB): Architected five drag-and-drop builders — Workflow, Website, Template, Form, and Pipeline. Every design serialises as a JSON schema persisted to MongoDB; schemas reconstruct full UI state on fetch, including component trees, layout, validations, and nested component relationships.
- Event-Driven Workflow Execution (SQS + Lambda): Designed the workflow execution engine where each DnD step-node supports if/else and switch branching configured through UI. Execution payloads pushed to AWS SQS, consumed by designated Lambda functions per processor type — enabling async, parallel step processing decoupled from the main server.
- Loyalty & Rewards Engine: Built a customer loyalty system on NestJS — 1 point per ₹4 spent, with automatic tier promotion (Bronze 25K · Silver 50K · Gold 100K pts). Points accrued transactionally on purchase events; full ledger history in MongoDB for audit and redemption.
- S3 Media Pipeline + Auth: Pre-signed URL upload flow (browser → S3 direct, no server bandwidth cost). Passport.js + JWT auth with RBAC across all builder APIs. AWS Comprehend sentiment scoring on reviews, cutting moderation effort by 60%.
- Serverless Migration: Re-architected monolith to Lambda + API Gateway + Redis, reducing monthly infra cost by 20% (₹12K → ₹9.6K).

- Dynamics 365 Migration Tool: Node.js Azure Function + React UI for Excel-to-Dynamics 365 ingestion with intelligent entity mapping, eliminating manual errors across 10,000+ records.
- Agricultural Data Portal: Vanilla JS + Power Automate portal automating post-submission processing, reducing manual data-handling time by 40%.
