I build web applications, internal tools, and the systems behind them.

Selected work

IBM · Professional experience

Internal products at IBM

I worked across interfaces, backend services and reporting pipelines for internal products. Some of that work involved AI workflows and assistants.

  • Built interfaces and backend workflows across multiple internal services
  • Connected internal services through custom API endpoints into one reporting pipeline
  • Built agentic workflows with watsonx Orchestrate, watsonx.ai and LangChain

Peer-to-peer commodity marketplace

I worked across the frontend and backend of Rootie, a peer-to-peer marketplace where businesses buy and sell commodities. I built product flows, forms and validation in Next.js against a GraphQL backend, and created a component library as the product grew.

  • Next.js frontend for a peer-to-peer commodity marketplace
  • GraphQL backend with Prisma and PostgreSQL
  • Complex forms and validation for marketplace workflows

Accessible communication platform

A communication platform for distributing information to blind and visually impaired people across Slovakia. I led a five-person team that built and deployed it on the client's own infrastructure.

  • A React Native app for iOS, Android and assistive devices like BlindShell and Corvus
  • A Next.js admin panel where staff compose and schedule messages
  • A NestJS REST API on Prisma and PostgreSQL, documented in Swagger

Also shipped

Commercial product site

MakeYourPod

A site for a custom pod manufacturer, with a configurator that updates the price as you change the spec. It emails the order and generates a PDF invoice.

Bachelor's thesis · Remote server monitoring & management

IISLabGuardian

My bachelor thesis: a system for monitoring and managing Linux and Windows servers. I built the agent that collects the data, the API that serves it and the dashboards administrators work in.

Performance rescue

Samtek

An Angular site that took about thirty seconds to load. I reworked how it fetched and handled data, refactored the legacy code around it, and got it under one second.

A little context

I'm Alex Vereš, a full-stack engineer in Košice, Slovakia. I've spent the last few years at IBM working on internal platforms, reporting pipelines and product tooling for data compliance and privacy.

I work comfortably at both ends of a product: shaping the interface and tracing a request through the backend. I care about accessibility, performance and software that remains understandable after launch.
