You will get MERN Stack Web Application — MongoDB, Express, React, Node.js (Your Spec)
Project details
Most MERN apps look fine on day one - then fall apart when real users arrive. I build them to last.
I'll develop your full-stack web application using the MERN stack (MongoDB, Express.js, React, Node.js) based on your spec, your features, your vision.
What I deliver:
✔ React frontend — TypeScript, Tailwind CSS, responsive, VITE
✔ Node.js + Express.js REST API — clean, documented
✔ MongoDB data layer — schema design, indexing, aggregations
✔ JWT authentication + role-based access control
✔ File uploads, real-time (WebSocket), third-party APIs
✔ Admin dashboard (Advanced tier+)
✔ Deployed — Vercel + Railway/Render or your preferred host
✔ Source code, README, Loom walkthrough on delivery
Reference: TypingBolt - 50K+ users, full platform rebuilt in 1 month on this exact stack. Running stable in production for 12+ months.
You bring the idea. I handle architecture, code, and delivery - end to end.
📌 Share your feature list to get started.

About Siddharthkumar
AI-Native SaaS Engineer | NestJS | Next.js | Multi-Tenant Systems
Surat, India - 1:13 am local time
50K+ users handled. 11M records migrated. 5 production systems shipped. AI-native. Architecture-first.
Most apps work at the start then fall apart when users, integrations and workflows grow. I get the architecture right from day one so you don't waste months rebuilding.
─── What I've shipped ───
Kavlo (live)
Enterprise contract intelligence SaaS. Multi-tenant with dual-layer isolation (Supabase RLS + app-level filtering — zero cross-tenant leakage). AI document pipeline: PDF → FastAPI/Celery → LLM parsing → PostgreSQL JSONB → validated UI. Vendor workflows triggerable from Slack, Claude or Teams via MCP server. Zero-downtime CI/CD on Azure Container Apps.
TypingBolt (live · 50K+ users)
Rebuilt an entire platform solo in 1 month. Migrated 50K+ users and 11M+ records from MySQL to MongoDB — zero downtime, zero data loss.
AI-personalized learning via LLM. Running stable in production for 12+ months.
Network File Search (github: sidvekariya510)
Distributed file search system across 25TB+ of data. Sub-second search. Built solo in 20 days using Go + Node.js + React.
─── How I work ───
I don't just write code — I design systems.
Architecture, scalability and code quality handled end to end. AI helps me move faster. Every decision and review is done by me.
→ You get the speed of a small team
→ With the accountability of one senior engineer

Steps for completing your project
After purchasing the project, send requirements so Siddharthkumar can start the project.
Delivery time starts when Siddharthkumar receives requirements from you.
Siddharthkumar works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements Review & Architecture Planning
I will review your provided specs, wireframes and business logic. Before writing any code, I will design the database schema (MongoDB) and finalize the system architecture to ensure we are building for scale from day one.
Frontend UI/UX Development
I will build the responsive, interactive frontend using React.js/Next.js. This includes establishing a clean component structure, setting up state management and ensuring pixel-perfect alignment with your design references.
