Hi there! I’m Muhammad Usama, a Senior Full Stack Engineer from Pakistan with 5+ years of experience building scalable web and mobile apps using TypeScript, React, Next.js, NestJS, Python, and Node.js. I’ve led end-to-end development of multiple production systems, boosting API performance by up to 50%, lowering bug rates by 35%, and trimming app load times by 40%.\n\nI bring a strong backend architecture background, caching strategies, database optimization, and a track record of collaborating effectively with product managers, designers, and QA in remote-first environments. I enjoy shaping architecture decisions, mentoring junior engineers, and delivering solid technical solutions that align with business goals.

Project Overview
Lively Pencil is an ambitious social platform for the literary and blogging community. Think: book lovers, microbloggers, and digital creators, all in one vibrant space—built on React Native and powered by a modern backend.
But while the vision was strong, the frontend architecture was a bottleneck.
The Challenge
When the team brought us in, they were dealing with a frontend that was holding back their ambitious literary platform. The app had great potential but was struggling with:
Critical Issues
Unstable user interface with frequent crashes
Poor performance affecting user engagement
Inconsistent design patterns across the app
Difficulty adding new features due to technical debt
Limited scalability for the growing user base
Our Approach
We didn’t just patch the problems—we reimagined the entire frontend architecture. Our goal was to create a platform that would grow with the literary community and provide a seamless experience for writers, readers, and bloggers.
Phase 1: Analysis & Planning
• Comprehensive code audit
• User experience analysis
• Architecture planning
• Technology stack evaluation
Phase 2: Rebuild & Optimize
• Complete frontend rewrite
• Modern component architecture
• Performance optimization
• Testing implementation
Project Overview
TalkieTotz is an intuitive, parent-guided mobile app designed to help bilingual families teach their toddlers a second or heritage language, regardless of the parent’s fluency level. Built as an MVP, the app offers a flexible, step-by-step language learning plan tailored to children under 4.
When the founder approached us, they already had a clear purpose: help parents through engaging, lesson-based content—available via a seamless mobile experience.
What they needed was a partner to bring their detailed Figma designs to life, advise on what makes a smart MVP, and execute across the entire product lifecycle: front end, back end, admin tooling, and deployment.
Like many early-stage founders, they didn’t just need code—they needed guidance, ownership, and speed.
MVP Reimagined for Data-Driven Learning
Instead of launching with in-app purchases, we proposed analytics tools to gather rich usage insights.
✓Built a Fully Custom Admin Panel
Clean, intuitive dashboard for managing lessons, tracking users, and updating content in real time.
✓Robust Backend in NestJS + MongoDB
Modern, scalable backend architecture allowing rapid iteration without compromising structure.
✓End-to-End Type-Safe API Integration
Using RTK Query with codegen for fully type-safe API requests from frontend to backend.
The client came to us with a simple ask: improve some screens and boost performance. The app worked—but just barely. Users were frustrated by slow load times, clunky transitions, and unexpected crashes. The backend hadn’t been touched in years, and the team struggled to build confidently or ship quickly.
We performed a deep audit, and it was clear: surface-level fixes wouldn’t cut it. If they wanted to grow, they needed to modernize from the ground up.
So we pitched a bold move: rethink the stack, rethink the future. They said yes. We got to work.
Our Solution
We implemented a comprehensive modernization strategy that included:
Complete architecture overhaul - Rebuilt the app with modern React Native best practices
Performance optimization - Implemented lazy loading, image optimization, and memory management
UI/UX redesign - Created smooth, intuitive interfaces that users love
Backend modernization - Updated APIs and database structure for better performance
Testing infrastructure - Established comprehensive testing to prevent future issues
