Gurmeet Singh Sethi

I architect and ship scalable web and mobile products—pairing strong system design with hands-on execution across React, Node.js, GraphQL, and AWS serverless. Fourteen-plus years delivering for teams that care about performance, clarity, and sustainable engineering practices.

  • Stack leadership: end-to-end ownership from UI and APIs to AWS backends and DevOps trade-offs.
  • Real-time & cloud: GraphQL, AppSync, subscriptions, Lambda, DynamoDB—built for scale and operability.
  • People & quality: mentoring, code review, and leading multi-disciplinary teams without sacrificing delivery speed.

How I articulate value

Skills on a resume tell recruiters what tools you know; these pillars describe how you apply them—architecture, delivery, leadership, and breadth.

Architecture & AWS serverless

Design enterprise-scale cloud-native systems: microservices, high-performance GraphQL APIs, Lambda and AppSync backends, and infrastructure tuned for reliability and cost.

Full-stack product delivery

Ship end-to-end products with React, Node.js, and TypeScript—from responsive UIs and reusable components to REST and GraphQL services, including real-time features via subscriptions and Apollo Client.

Leadership & engineering excellence

Own technical strategy and system design; mentor engineers and run rigorous code reviews. Experience leading a 15-person cross-functional team and clearing backlogs to accelerate delivery.

Mobile, integrations & security-minded delivery

Build React Native experiences for iOS and Android; integrate payments and SMS workflows; apply secure patterns (AWS Parameter Store, environment-based config) across stacks including PHP, Java, and .NET when needed.

Technical expertise

Organized by depth and responsibility—not every skill is used every day, but together they describe the systems you can own, migrate, or improve.

Primary stack — where I go deepest

Day-to-day ownership across the product surface: UI, APIs, and cloud backends.

Frontend & client architecture

Component-driven UIs, performance-conscious rendering, and patterns that scale across teams.

React.jsTypeScriptJavaScriptHTML5SCSS

Backend, APIs & real-time

Schema design, subscriptions for live updates, and services that stay observable and maintainable.

AWS & infrastructure

Serverless-first backends, event-driven flows, and pragmatic use of managed services.

Platform, data & delivery

Everything that keeps systems running predictably from commit to production.

Data stores & caching

Modeling for query patterns, migrations, and the right store for the job.

DevOps & quality gates

CI/CD, repeatable deployments, and collaboration rituals (Agile/Scrum) that protect velocity without sacrificing quality.

DockerKubernetesGitHub ActionsJenkinsGitJira

Breadth — polyglot & mobile

Comfortable jumping into varied codebases and integration-heavy environments.

Additional languages & frameworks

Maintain and extend legacy services, integrate third parties, and deliver mobile apps where product demands it.
