Who I am

A quick look at my background, what drives me, and how I approach building software end to end.

3+Years experience
40%Latency cut
385+DSA problems

M.Tech graduate from MNNIT Allahabad with 3+ years in the industry - including 10 months at SAP Labs and 2.5 years as a Full Stack Developer at Nagarro - I like building things that real users actually depend on. Full Stack AI Engineer with 3+ years of experience building scalable web systems across video streaming, enterprise analytics, and cloud-native applications. Improved video startup latency by 40% using HLS-based adaptive streaming, reduced database query latency by 30%, and enhanced UI performance by 20% through Angular rendering strategies. Strong in system design, distributed systems, and AI-powered features.

1

Improved video playback startup time by 40% via serverless HLS adaptive streaming (S3 → Lambda → FFmpeg)

2

Enhanced frontend performance by 20% TBT reduction using Angular OnPush strategy - 60 FPS under high data load

3

Architected a rail asset management backend serving 170K+ assets with sub-second real-time updates at Nagarro

कर्मण्येवाधिकारस्ते मा फलेषु कदाचन । मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि ॥“You have the right to perform your actions, but never to the fruits thereof. Let not the fruits of action be your motive, nor let attachment be to inaction.”

A multiplayer debate platform where players join rooms, argue for or against a motion, and get scored by an AI judge - with optional human judges whose reliability is itself scored. Supports two debate modes: Alternate (structured turn-by-turn) and Buzzer (grab-the-mic free-for-all). Live audio runs over WebRTC; everything else flows over Socket.IO.

Proud to have built alongside great teams

Companies and teams I've been part of along the way.

Full Stack Web App - React, Angular, Node.js, AWS

Freelance Services

Full-stack engineer available for client projects - from a professional online presence to production-grade SaaS platforms. You're not just paying for code - you get architecture, integrations, secure deployment, scalability, and professional execution that AI tools alone can't deliver.

What I build
React / Angular / Next.js frontends with clean, responsive UI
Node.js + Express REST APIs and authentication systems
Database design & integration - PostgreSQL, MongoDB, or any publicly available database
AWS / Vercel / Netlify deployment with CI/CD pipelines

  • Responsive, SEO-ready UI
  • Custom design & branding
  • Cloud deployment & domain setup
  • -Authentication & user accounts
  • -Database & admin dashboard
  • -Payments & subscriptions
  • Full source code ownership
  • Everything in Launch
  • Authentication & user accounts

  • Everything in Growth
  • Scalable, multi-tenant architecture
  • Payments & subscriptions
  • Analytics & monitoring
  • AI-powered features (optional)
  • Performance & security hardening
  • Full source code ownership

All pricing shown is a starting estimate. Final cost depends on project complexity, integrations, business requirements, third-party services, and deployment needs.

Quick Services

Don't need a full build? I also take on small, one-off jobs - fix a bug, add a single feature, or get your site audited. Pricing scales with the work, and you always get an exact quote before anything starts.

Bug Fixing
From ₹1,500priced per bug

Something broken on your live website or app? I diagnose and fix it. The cost scales with how deep the bug goes - a quick UI or logic fix sits at the lower end, trickier backend, data, or integration issues cost more.

New Feature
From ₹5,000scoped per feature

Need to add just one thing to an existing site or app - a new page, form, integration, dashboard widget, or API endpoint? Final price depends on the size and complexity of the feature, quoted before we start.

Bug Audit & QA
From ₹3,000per site / app

I go through your website or app, hunt down bugs, broken flows, and edge-case issues, and hand you a clear report. Fixing the findings is available on top, quoted by severity.

Why Work With Me?

You're paying for architecture, deployment, integrations, scalability, and ongoing maintainability - not just generated code.

Frequently Asked Questions

How I Work

I work on your project following the steps below. Revisions may occur after the delivery date.

01
Requirement Gathering

Client purchases the project and shares all requirements, references, branding details, content, and feature expectations.

02
Service Agreement

Once requirements are clear, we lock them into a simple service agreement - scope, deliverables, pricing, timeline, revisions, and payment terms - so both sides are aligned before any work begins.

03
Planning & Wireframing

I analyze the requirements, finalize the project structure, and create wireframes or UI concepts for approval.

04
Design & Development

I develop the website/application with responsive design, required features, animations, integrations, and optimizations.

05
Review & Feedback

Client reviews the delivered work and shares feedback or revision requests if needed.

06
Revisions & Final Delivery

I implement the requested revisions, perform final testing, and deliver the completed project files/live deployment.

07
Deployment & Support

I assist with deployment, hosting setup, bug fixes, and post-delivery support if included in the package.
