You will get Full Stack Engineer | Built platforms for 10,000+ Concurrent Users
Project details
Most backend developers write code. I build systems that survive real-world pressure.
I architected a cloud platform managing 8,000+ screens across India and the US — 99.9% uptime, 10,000+ concurrent users, built on Node.js, NestJS, and AWS. That was production, at scale, with zero tolerance for failure.
What sets this apart:
▪ Team Lead-level engineer — I've led teams of 6 and delivered enterprise systems from scratch, not a junior learning on your budget.
▪ AWS Certified — deployment, scaling, and CI/CD are included, not an afterthought.
▪ Daily updates — you always know what's built, what's next, no radio silence.
▪ Clean tested code — Jest tests, 80%+ coverage, TypeScript throughout.
▪ Cross-industry experience — HIPAA healthcare systems, Stripe payments, WebRTC real-time communication.
If your project needs to work reliably and scale gracefully — let's talk.

Full Stack Engineer | Built APIs for 10,000+ Concurrent Users
Surat, India - 5:49 pm local time
I've been that engineer.
I'm Neha, a Senior Full Stack Developer and Team Lead with 5+ years building enterprise-grade systems using Node.js, NestJS, Next.js, and AWS. I don't just write code — I architect systems that stay alive under pressure.
What I've actually built:
▪ A cloud-based digital signage platform managing 8,000+ screens across India and the US — running at 99.9% uptime on AWS ECS + Cloudflare, serving 10,000+ concurrent users with zero tolerance for downtime.
▪ HIPAA-compliant healthcare backend systems with PostgreSQL, TypeORM, and JWT authentication — built to the strictest data security standards required by US healthcare law.
▪ A real-time WebRTC voice support system using Twilio that increased customer satisfaction by 15%.
▪ A role-based SaaS subscription platform with Stripe payments, serving 1,000+ active users with zero unauthorized access incidents.
My core stack:
Node.js · NestJS · Next.js · TypeScript · PostgreSQL · MongoDB · Redis · React.js · AWS (ECS, Lambda, S3, RDS, API Gateway, CloudFront) · Docker · CI/CD
AWS Certified Developer. HackerRank Certified React Developer.
I've led teams of 6 engineers, run CI/CD pipelines, integrated AI-assisted code review tools, and delivered systems that enterprises trust with real data and real users.
Who I work best with:
Founders and engineering teams who need someone who takes ownership — not someone who waits to be told what to do. If you need a reliable senior engineer who communicates clearly, delivers on time, and genuinely cares about your product working — let's talk.
What happens when you hire me:
✓ I read your requirements carefully before writing a single line of code
✓ I ask the right questions upfront so there are no surprises later
✓ I deliver clean, documented, tested code — not just "works on my machine"
✓ I stay available and communicate progress proactively
Drop me a message describing your project. I'll tell you honestly whether I'm the right fit — and if I am, I'll show you exactly how I'd approach it.
Steps for completing your project
After purchasing the project, send requirements so Neha can start the project.
Delivery time starts when Neha receives requirements from you.
Neha works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & requirements review
I start by thoroughly reviewing your project requirements, asking the right questions to understand your goals, users, and technical constraints. No assumptions — everything is clarified upfront before a single line of code is written.
Architecture & technical planning
I design the system architecture — database schema, API structure, authentication flow, and cloud infrastructure plan. I share this with you for approval so we're aligned before development starts. No surprises mid-project.
