Full Stack Developer · APIs & scalable back-ends · 5+ yrs · Ahmedabad, India

Hi, I'm Satish — I build fast, scalableback-ends & APIs.

Full Stack Developer with 5+ years — most of it deep in the server layer, architecting and scaling RESTful APIs and microservices in Node.js and Express, backed by MongoDB, MySQL, and Redis caching. I design reliable, low-latency back-ends (sub-200ms responses, 99.9% uptime) for high-traffic platforms with 100K+ users, then pair them with clean React and Next.js front-ends to ship features end-to-end.

What I do

  • Backend APIs & Microservices

    Design and build RESTful APIs and microservices in Node.js/Express — clean contracts, sensible boundaries, and sub-200ms responses at 99.9% uptime.

  • Performance & Scaling

    Redis caching, MongoDB/MySQL query tuning, and load hardening for high-traffic platforms — cutting latency and database load under peak demand.

  • Full-Stack Feature Delivery

    Ship features end to end — pairing reliable back-ends with clean, responsive React and Next.js front-ends, from wireframe to production.

  • Payments & Integrations

    Secure Stripe payment workflows (PCI-DSS) and resilient third-party integrations — SendGrid, analytics, and external APIs that don't fall over.

  • API Security & Reliability

    JWT auth, rate limiting, input validation, and logging/analytics instrumentation so services stay secure and observable in production.

  • Code Review & Mentorship

    Raise team standards through code reviews, refactoring, and mentoring juniors — cutting duplication and delivery time while keeping quality high.

How I work

  1. 01

    Understand the problem

    Start from the users and the numbers — traffic, latency budgets, failure modes — before writing any code.

  2. 02

    Design the contract first

    API-first: clean REST contracts, sensible service boundaries, and data models that stay fast as they grow.

  3. 03

    Build for production

    Auth, rate limiting, input validation, and logging from day one — secure and observable by default, not bolted on later.

  4. 04

    Measure, then optimize

    Profile hot paths before tuning. Redis caching and query optimization go where the data says — that's where the ~35% latency cuts come from.

  5. 05

    Ship & raise the bar

    Zero-downtime CI/CD deploys, code reviews, and mentoring — leave the codebase and the team faster than I found them.

Common questions

Are you available for work?

I'm not actively job-hunting right now, but I'm always open to interesting problems, contract conversations, and networking. Email is the fastest way to reach me.

What's your core stack?

Node.js and Express on the back-end with MongoDB, MySQL, and Redis, paired with React and Next.js on the front-end. Most of my depth is in the server layer — APIs, microservices, and performance.

Do you work full-stack or backend only?

Both. I spend most of my time architecting and scaling back-ends, but I ship features end to end and regularly build the React/Next.js front-ends that sit on top of them.

What kind of projects do you take on?

High-traffic platforms that need reliable, low-latency APIs — payments, real-time features, data-heavy dashboards, and SEO-friendly Next.js front-ends.

Where are you based?

Ahmedabad, India — I currently work remotely with a Pune-based team. I've worked with distributed teams across time zones and I'm comfortable collaborating async.
