I build backend systems that stay boring in production. Seven years designing APIs, real-time platforms, and services for FinTech and EdTech — owned end-to-end, from the first schema to the 2 a.m. page.
I care about the unglamorous parts — the schema that scales, the query that stays fast, the service that simply refuses to fall over. Seven years across FinTech and EdTech, owning systems from API design through caching, deploys, and the on-call pager.
Today I run LevnTech, shipping Node.js and TypeScript backends for clients worldwide — and wiring in AI/LLM capabilities only where they genuinely earn their place.
Hover a node to see where it earns its keep.
Built and maintained CMS-driven web pages with secure client-side scripting, and managed source control across a distributed team.
Revamped e-commerce UIs with React, Redux and SCSS; +25% engagement, −15% cart abandonment, −30% initial load via lazy-loading and code splitting.
Built a real-time finance data-insight dashboard on Node/TS/Express/Socket.IO, streaming live market data with Redis hot-path caching and Dockerized HA deploys.
Owned the backend for a real-time K-12 student-monitoring platform — Socket.IO + Redis adapter for horizontal scaling, Kafka.js analytics, RBAC across three roles.
Ship Node.js/TypeScript backends for global clients end-to-end, integrate AI/LLM pipelines where they earn their place, and build LevnTools.
An Android app to generate, style and scan QR codes — a focused, on-device QR toolkit, published under LevnTools.
An Android app that compresses photos down to a precise target size in KB — for uploads with strict file-size limits.
