NEXA is a 90-day mentorship for React and Angular developers who want to add backend skills, build real systems, and land full-stack roles.
Watch Adil explain exactly who NEXA is for and what you will achieve in 90 days.
No commitment. 30 minutes. Walk away with a clear path forward.
Does This Sound Like You?
Stuck in Frontend
You are great at React or Angular but keep losing full-stack roles to developers who know backend.
Salary Has Plateaued
Full-stack engineers around you are earning significantly more. You can see the gap and it is growing.
Self-Learning Did Not Work
You tried Node.js tutorials on YouTube. You built nothing real, lost momentum, and moved on.
No Backend Portfolio
Even if you learned something, you have nothing to show employers to prove it.
No Structure or Accountability
Without a clear roadmap and someone to hold you accountable, progress never sticks.
NEXA was built specifically to solve every one of these problems in 90 days.

Most courses teach you theory and leave you on your own. NEXA gives you a structured backend curriculum, real projects you actually build, working professionals mentoring you through every phase, and placement support until you land the role. Everything is designed around one outcome, getting you hired as a full-stack engineer.
NEXA does not start from zero. It starts from where you already are. Your React or Angular skills are your foundation and we build the backend layer on top of that.
You will be trained by working professionals currently employed in full-stack and backend roles at top companies. They bring real problems, real codebases and real standards into every session.
No todo apps. No throwaway exercises. You build production-grade backend systems that go straight into your portfolio and give you something concrete to show in every interview.
NEXA does not end when the 90 days end. You get mock interviews, resume reviews, referrals and active placement support until you land your full-stack role.

See If NEXA Is Right For You →The Curriculum
NEXA covers the complete backend stack that companies actually hire for. Every topic is taught by working professionals through real systems, not isolated exercises.
Understand how the backend actually works. Learn the V8 engine, NPM, CommonJS modules, built-in Node modules, streams, buffers and how to build your first HTTP server from scratch.
Build production-grade REST APIs with Express. Learn routing, middleware, route grouping, controllers and global error handling the exact structure companies expect in a backend codebase.
Design and manage real databases. Learn collections, CRUD operations, schema design, validation, population, middleware hooks and how to connect your database to a live application.
Implement complete auth systems with password hashing, bcrypt, JWT access and refresh tokens, role-based access control and protected routes. A non-negotiable skill for every full-stack role.
Go beyond the basics with pagination, search, filtering, file uploads with Cloudinary, websockets with Socket.io, Redis caching, rate limiting, XSS protection and NoSQL injection prevention.
Learn how real backend codebases are structured. MVC pattern, services layer, repository pattern, environment configuration, logging with Morgan and Winston and performance optimization.
Work the way modern engineers work. Use GitHub Copilot and AI debugging tools to write better code faster and solve problems the way top companies expect you to.
What You Will Build
Learning without building is just theory. In NEXA you ship real projects that go straight into your portfolio and straight into your interviews.
Build a fully structured API with controllers, routers, middleware, database integration, error handling and Postman tested endpoints. Your first production-grade backend.
Build signup, login, JWT access and refresh tokens, protected routes and role-based access from scratch. Every full-stack interview will test you on this and you will have already built it.
Build a live feature using websockets and Socket.io. Broadcasting, real time updates and event-driven backend logic that shows employers you can handle modern application requirements.
Your final project combines everything. A complete backend connected to your existing frontend skills, deployed live, with auth, database, APIs and clean architecture. This is the portfolio piece that gets you hired.
Your Journey
NEXA is not a dump of videos and topics. Every week is structured with a specific goal so you always know where you are, what you are building and what comes next.
Node.js and Server Foundations
You start by understanding how the backend world actually works. The V8 engine, NPM, core Node modules, streams, buffers and building your first HTTP server. By the end of Week 2 you will have moved from frontend thinking to backend thinking.
Express.js and REST API Development
You learn to build clean, scalable APIs with Express. Routing, middleware, controllers, route grouping and error handling. Week 4 closes with your first milestone, a fully working CRUD API built and tested with Postman.
🏁 Milestone 1: Build and test a complete REST API with full CRUD operationsMongoDB, Mongoose and Database Design
You connect your APIs to a real database. Schema design, validation, population, middleware hooks and querying strategies. By Week 6 your API is talking to a live MongoDB Atlas database.
Authentication, Authorization and Security
You implement a complete auth system from scratch. Password hashing with bcrypt, JWT access and refresh tokens, role-based access control and protected routes. Week 8 closes with your second milestone.
🏁 Milestone 2: A complete authentication and authorization system, live and testedAdvanced Backend Features and Clean Architecture
You go deeper into what separates junior backends from senior ones. Pagination, file uploads, Redis caching, websockets with Socket.io, XSS protection, rate limiting and clean MVC architecture with a services layer.
🏁 Milestone 3: A real time application with advanced backend features and clean architectureCapstone Project and Deployment
You build your final full-stack capstone project combining everything you have learned. Backend APIs, authentication, database, real time features and a frontend you already know how to build. Then you deploy it live.
🏁 Milestone 4: A fully deployed, production-grade full-stack capstone project in your portfolioInterview Preparation and Placement Support
Mock interviews, resume building, LinkedIn profile review, referrals and active placement assistance. This phase does not have an end date. It continues until you land your full-stack role.
🏁 Milestone 5: Your first full-stack job offerYour Outcomes
Every outcome from NEXA is something concrete you can show, use and build your career on from day one.
You graduate with a fully deployed, production-grade capstone project that shows employers exactly what you can build. Not a certificate. Actual working software with your name on it.
Node.js, Express.js, MongoDB, authentication, authorization, file uploads, real time features, clean architecture and deployment. The exact skills full-stack job postings ask for.
Multiple mock interviews, an ATS-friendly resume, polished LinkedIn profile and practiced technical and HR rounds until you are genuinely confident walking into any interview room.
You are not on your own after the program ends. You get job referrals, application support and active placement assistance from the Sidillus team until you land your full-stack role.
Beyond the capstone you will have built multiple backend systems across the 90 days. A REST API, an auth system, a real time application. Each one backs up everything on your resume.
You walked in as a frontend developer. You walk out as a full-stack engineer. That is a completely different set of opportunities, salary brackets and career trajectories open to you.
Everything above is what NEXA is designed to deliver. The only thing missing is you.
