What I'm looking for

Passionate Full Stack Engineer open to Software and Mobile Application Developer roles. I use React, Next.js, TypeScript, and Node.js to build scalable apps. Experienced with REST APIs, databases (MongoDB, Redis), OpenAI APIs, and Embedding-based search to build high-performance, SaaS, and AI solutions

At Cosmemporium Limited, I build and maintain eCommerce and SaaS platforms, from Next.js and React storefronts to the NestJS and Node.js services behind them. I designed REST APIs for payments, inventory, and order fulfillment, and integrated Stripe, Shopify, and client ERP systems.

I added OpenAI-powered product search, recommendations, content generation, and document processing. To improve response times under production load, I tuned PostgreSQL queries and indexes, cached hot reads in Redis, and moved slow work into background jobs.

At Omnisoft, I built SaaS features with React, Next.js, ASP.NET Core, and NestJS. I implemented role-based authentication, payment integrations, real-time messaging, and background workers, and introduced embedding-based search and OpenAI-powered summaries.

Earlier, I developed web platforms and APIs at Venre and VisNext, and built Flutter apps at Tech Hunter and Bitlogicx. My selected projects include CarSpot NL, four websites for an Australian disability and mobility services client, and product synchronization tools for Seagulls Industrial.
