Project details
Build a Scalable, High-Performance Social Ecosystem.
With 12+ years of Full-Stack experience, I architect high-performance social networks using the Next.js, Node.js (NestJS), and Socket.io stack. I don’t just build feeds; I build secure, real-time communities that scale.
What sets this project apart:
Real-Time Engine: No slow refreshes. I implement sub-second engines for instant messaging, live notifications, and dynamic activity feeds.
Media Optimization: I use AWS S3 and CloudFront for automated image/video compression, ensuring lightning-fast load times globally.
Security & Privacy: From JWT-based auth to encrypted private chats and RBAC, I ensure user data is protected from Day 1.
Clean, Scalable Code: I follow SOLID principles and provide full documentation, making it easy for your team to maintain or scale the platform.
Standard Features:
Personalized User Profiles & Follower Systems
Interactive Feeds (Likes, Comments, Shares)
Real-time 1-on-1 and Group Messaging
Advanced Search & Discovery Algorithms
Admin Moderation Dashboard
Stop using rigid "off-the-shelf" tools. Own your custom, enterprise-grade community today.

Senior GCP Platform Engineer - Cloud Infrastructure & DevOps
Kirit and the team at Flexgrew Technologies worked with us for over a year on a white-label social commerce platform, and honestly, they were one of the best teams I've worked with on Upwork.
The project was not small. We're talking a full social networking platform with real-time messaging, social feeds, media sharing, marketplace, groups, pages, user profiles, the whole nine yards. Kirit and his team handled all of it, frontend and backend, and they never once made me feel like the project was too big or too messy for them.
What I really appreciated is that they got what we were trying to build. They weren't just taking tickets and pushing code. They understood the product, asked the right questions, and more than a few times came back with solutions that were better than what I originally asked for. That kind of ownership is rare and hard to find.
A few things worth calling out. Their communication was solid the entire time. Over a full year, we never had a single miscommunication or dropped ball. They showed up, they delivered, and when something needed more time, they said so upfront instead of going quiet. That alone puts them ahead of 90% of the teams I've worked with.
Technically, the team is strong across the board. PHP, JavaScript, database work, API integrations, server configuration, UI, you name it. They moved between layers of the stack like it was nothing. And the code quality was consistently clean, which matters when you're building something you plan to maintain long term.
But honestly, the thing that stands out the most is just how easy they are to work with. No drama, no ego, no excuses. Just a solid team that takes pride in their work and treats your project like it's their own.
If you're looking for a full-stack team that can own a complex platform end to end and actually make your life easier in the process, Kirit and Flexgrew are the real deal. I'd hire them again without thinking twice.

— Upwork client, 395-hour social commerce platform build
That review captures how I work. I'm a senior full-stack developer with 14+ years of experience, specializing in social platforms, SaaS products, and real-time applications.
WHAT I BUILD:
- Social networking & social commerce platforms — feeds, messaging, marketplaces, profiles, groups, media sharing
- SaaS products — multi-tenant, billing, dashboards, APIs
- Real-time systems — WebSocket chat, live notifications, pub/sub architectures
- High-performance backends in Node.js and Go
- Modern frontends in Next.js, React, Vue
MY STACK:
Next.js, Node.js, Go (Golang), React, Vue, Laravel, PostgreSQL, MongoDB, Redis, WebSockets, AWS, GCP
OWN PRODUCT:
I co-built flexgrew.cloud — a production WhatsApp Business SaaS with AI chatbots, bulk campaigns, and multi-tenant architecture. I don't just build for clients. I operate my own SaaS too.
HOW I WORK:
- Senior-level only — I architect before I code
- Daily updates, no ghosting, no dropped balls
- I ask questions before writing code
- Available for US and EU hours
- I write code your next developer can read 6 months later
Send a message describing what you're building — I'll respond within a few hours with a clear next step.
Steps for completing your project
After purchasing the project, send requirements so Kirit can start the project.
Delivery time starts when Kirit receives requirements from you.
Kirit works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & System Architecture Design
We’ll define user stories, database schemas (PostgreSQL/MongoDB), and API endpoints. I’ll map the real-time architecture to ensure your social platform handles high concurrency and media scaling from Day 1.
Backend Engine & Real-Time Setup
I’ll build a secure Node.js/NestJS backend with JWT auth. I’ll integrate Socket.io for instant messaging and live notifications, plus AWS S3/CloudFront for optimized image and video processing.
