Hi, I am

Mohd Touseef JamalFull-stack Engineer& Mobile Developer

I started my career as a freelancer, building complex ERP systems that saved businesses more than $1,000 per month in operational costs.
Over 5+ years, I've built ERP systems, CRM systems, LMS platforms, e-commerce solutions, and mobile apps.

Beyond engineering, I take product ownership, contribute to business growth, work across product management, partner directly with clients, and lead technical decisions.

Previously, I helped scale InterviewReady (opens in a new tab) across engineering, content, marketing, product, and UX/UI.

Most recently, at The Product Highway (opens in a new tab), I led the development of CastFast (opens in a new tab), a multi-tenant ERP platform, and GrayPorter (opens in a new tab), an AI-powered e-commerce platform.

Services

What you can hire me for.

Whether you need a product built from scratch or an existing one improved, here's where I add real value.

01

Website Design & Development

Full-stack web products, from wireframe to deployed.

02

Mobile App Development

iOS & Android apps built with React Native — one codebase, store-ready.

03

UX/UI Design & Improvement

Audits, redesigns, and new interfaces users actually enjoy.

04

Project Management

End-to-end ownership: timelines, sprints, stakeholder updates.

05

Team Leadership

Building and leading dev/design teams that execute with clarity.

06

Technical Consulting

Architecture review, tech stack decisions, or just a second opinion.

Experience

Where I've shipped.

Companies and teams I've built with — from startup velocity to enterprise scale.

Apr 2025 - Oct 2026 (1 Year 6 Months)

  • CastFast (Multi-tenant ERP Platform) - Owned front-end architecture and delivery as the client-facing engineer, leading a 4-member team and design review, working directly with the German founding team from requirements to launch, in 8-9 months.
  • E2E Testing & Error Monitoring - Integrated Playwright suite for auth, RBAC controls and critical workflows; configured Sentry for error monitoring and real-time alerting, reducing regression overhead and mean time to detection.
  • Migrated a legacy sub-module directly into the main repository; resolved React version conflicts, and eliminated external dependency.
  • Built a session-based access-locking mechanism to prevent concurrent access and multi-tab conflicts, ensuring data integrity.
  • GrayPorter (E-commerce Platform) - Led the end-to-end revamp of the storefront, driving product research, design reviews and front-end architecture.
  • Built an AI-powered voice shopping interface by integrating an internal RAG and tool-calling platform, enabling customers to ask product questions, fetch live pricing, get camera recommendations, and receive order assistance.
  • Re-architected server state using React Query (handled request deduplication, background sync, stale-while-revalidate), eliminated SSR hydration inconsistencies and removed duplicate in-flight requests to serve from cache instead of re-hitting APIs.
  • Reduced bundle size from 4.2MB → 2.8MB & improved Time-to-Interactive by 30% by deferring non-critical module loading.
  • Improved product page Lighthouse performance (23 → 64): LCP 5.2s → 2.4s, and TTFB 2.7s → 1.1s, with FCP and CLS gains.
  • Mixpanel integration to instrument product features and user flows, giving the team visibility into how customers move through the store and where they drop off.

Oct 2022 - Apr 2025 (2 Years 7 Months)

May 2021 - Sept 2022 (1 Year 5 Months)

    The Logging Rollercoaster: How My Tiny Node.js Project Turned Into a Monster

    In any production system, logging is your eyes and ears into the App behavior. From tracing API requests and catching database operation failures to monitoring external service responses and tracking business logic errors, a proper logging strategy with tools like Winston helps you understand exactly what is happening in your system.

    Video Transcoding Service using node.js

    We will be learning how to convert video into different resolutions and break them into chunks and support adaptive streaming. A video transcoding service primarily converts video files from one format or encoding to another. It includes changing codecs, adjusting bitrate, changing resolutions, or modifying frame rates and so on.

    Hosting node.js backend on a custom server using Nginx

    Few days ago, I have to host a node.js backend written in TypeScript on a custom server of my client (no aws & no other hosting provider). I have to setup everything from by myself and it took me almost 2 days to host it properly. I have read many blogs and watched many YouTube videos about nginx, http caching, load balancing, api gateway, reverse proxies, ssl certificate, ssh, port forwarding, url redirection, etc but never have I ever implemented these concepts in a real project.

ACCEPTING NEW WORK
