Tochukwu Nwosa
Fullstack Engineer
I build the whole thing — from database to UI. React and Next.js on the frontend. Node.js, NestJS, and MongoDB on the backend.
Currently: Brainzcode (full-time) + Kinplus (contract)
I'm a Fullstack Engineer with 3+ years building and shipping production web software — frontend to backend.
On the frontend: React, Next.js, TypeScript — pixel-perfect UIs and performance that moves the needle. On the backend: Node.js, NestJS, MongoDB, Supabase — API design, auth systems, and business logic built for real traffic.
Currently full-time at Brainzcode. I also built and run MyTreda — an inventory and business management platform with 80+ registered businesses and 1,400+ products tracked.
Recent wins:
- ✓Built and shipped MyTreda — full-stack product with 80+ businesses, 460+ sales records, 3,000+ activity logs
- ↑Improved LMS platform performance by 40% (4.5s → 2.7s), Lighthouse 65 → 92
- ↑Increased user engagement by 30% through UX and architecture improvements
- ✓Delivered 10+ client projects with consistent 98+ PageSpeed scores
Tech stack: React, Next.js, TypeScript, Node.js, NestJS, MongoDB, Supabase, Tailwind CSS
Open to remote fullstack engineering roles. GMT+1 — solid overlap with EU and US East Coast.
Featured Projects
Personal products and client work showcasing performance optimization, modern architecture, and user-focused design
MyTreda
Inventory & business management platform
Full-stack business management platform I built and currently operate. Handles inventory tracking, sales records, debt management, and daily business workflows for small businesses. I designed and built everything — the Next.js frontend, the NestJS REST API, MongoDB schema, authentication system, activity tracking, and deployment pipeline. Not a side project. A running product with real users.
ClaimMate
AI-powered insurance claim report generator
Built the full product — Next.js frontend, Supabase backend, OpenAI API integration for intelligent narrative generation, role-based authentication, and a PDF/Word export pipeline. Optimized with Next.js SSG for sub-2s load times and a 95+ Lighthouse score.
Tech LinkUp
Event discovery platform for Nigeria's tech ecosystem
Platform connecting tech professionals with events across Nigeria. Built a Supabase backend with real-time filtering, optimised database queries, and event submission workflows. Currently hosts 169 published events across in-person, virtual, and hybrid formats. Performance-first architecture with debounced API calls and virtualized lists.
Kinplus Technologies
Corporate website for engineering & construction firm
Modern corporate website with headless CMS integration for easy content management. Achieved 98+ PageSpeed through image optimization, lazy loading, and lean component architecture.
KondoHQ
Real estate platform — dashboard & application flow
Contributed as a frontend engineer on a real estate SaaS platform. Built the user dashboard, dashboard landing page, the full flow from viewing to applying for a property, the market insights page, and both user and admin settings pages. All implemented pixel-perfect from Figma designs using Next.js and TypeScript.
