About

Senior Software Engineer with 5+ years building and operating production backend, cloud, and AI systems — applied ML since 2021, production LLM agents today. Currently at NatWest, previously Technical Lead at Forwood Safety and full-stack engineer at Launchpad Fintech. I work day to day in Python, AWS, Terraform, Docker, and GitLab CI/CD, and I'm certified on HashiCorp Terraform, Claude, and AWS.

At NatWest I own the infrastructure behind our AI agent platform: MongoDB Atlas and Aurora PostgreSQL provisioned through reusable Terraform modules, services running on AWS ECS, releases moving through GitLab CI/CD. I've co-designed banking agents on OpenAI and Gemini that run in production, and cut roughly $10,000 a year from our AWS bill by fixing how those services scale.

I also built the team's accessibility tooling — a frontend code scanner and a GitLab CI/CD template that drops into any pipeline in three lines. Chosen as the strongest of three solutions built across the business, it now runs in 12 feature teams and has caught around 4,000 accessibility issues before they reached production. It's the work I'm proudest of: it makes the right thing the easy thing for every team that adopts it.

I've moved from full-stack developer to release manager to Technical Lead, so I've owned more than code — release cycles, mentoring, and architecture calls alongside product, mobile, and frontend teams. The part I enjoy most is the unglamorous part: making a system observable, predictable, and cheap to run. I've taken services from a whiteboard sketch to production, and I've been the person on call when they broke.

The work I want more of is exactly this — AI systems held to real engineering standards: observable, cost-aware, and boring to operate.

NatWest

Gurugram, India

  • Built the team's AI agent platform on AWS ECS, orchestrated with Terraform and GitLab CI/CD.
  • Co-designed production banking workflow agents — agent coaching and request flows, product requirements intake, and source of funds verification — in Python with OpenAI, Gemini, and LangChain.
  • Built Accessibility Checker, a Kiro skill that scans frontend code for accessibility issues and suggests fixes, alongside a dashboard for tracking them across services.
  • Packaged it as a reusable GitLab CI/CD template that drops into any pipeline in three lines, publishing issues, suggested fixes, and an HTML report as a build artifact.
  • Selected as the strongest of three competing accessibility solutions and rolled out to 12 feature teams across the Commercial & Institutional (C&I) business area, where it has caught roughly 4,000 accessibility issues before they reached production.
  • Implemented ECS auto-scaling that cut AWS spend by ~$10,000 a year.
  • Own the team's MongoDB Atlas and Amazon Aurora PostgreSQL infrastructure end to end, standardized through reusable Terraform modules published to a private module registry.
  • Led multiple production releases, including the tech go-live for the AI agents and a release shipping three agents with a Python and MongoDB backend service — owning CI/CD promotion, rollout validation, health checks, and post-release monitoring.

ShopHub · E-Commerce

Problem: Most e-commerce demos keep catalog and checkout glued to server-rendered pages, so there is no stable contract for a separate storefront, checkout is unsafe on network retries or double-submits, and session-style auth breaks down once the UI and API run on different origins.

Tech: Next.js 15 (App Router, TypeScript, Tailwind) storefront; Django 5 and Django REST Framework API; JWT auth; idempotent checkout; OpenAPI via drf-spectacular; optional Paytm handoff; SQLite by default with a PostgreSQL-ready path; backend and frontend tests.

Result: End-to-end flow from catalog and cart through signup, login, checkout, and order tracking, plus staff catalog APIs and architecture notes for split deploy (API vs storefront).

Cloud Cost Guardrail Analyzer

Problem: Cloud teams often miss idle resources, spend spikes, and owner-specific savings opportunities until costs have already increased.

Tech: AWS Lambda, API Gateway, EventBridge, Cost Explorer, CloudWatch, EC2, RDS, Terraform, FastAPI, Next.js, and CI validation.

Result: Detects idle EC2/EBS/RDS resources, shows month-to-date cost and top services, and sends owner-aware Gmail/WhatsApp alerts with remediation steps.

Live demo

KIMS Document Management System

Problem: KIMS University managed document approvals over email, with no audit trail, no role boundaries, and no way to see where a document was stuck.

Tech: Next.js and Django with PostgreSQL; role-based access control; WebSockets and Redis for real-time commenting; AWS SES for notifications.

Result: A full document workflow with role-scoped permissions, upload and approval APIs, live comment threads, and email notifications on every state change.

Freelance client project — deployment retired by the client.
