Web and mobile apps for energy clients, including TAURON

Senior Frontend Software Engineer Rzeszów, PL · Hybrid Aug 2025 — Present

THE CHALLENGE

Keep Angular web and Capacitor mobile apps moving in parallel for energy-sector clients — dashboards, ops tools, and an AI chat — while the rest of the product team ships around you.

CONTEXT

I work on the frontend at ONHSR: Angular for the web, Capacitor for mobile, same codebase where it makes sense. A big chunk of the work is for TAURON — reports, operational screens, and a chatbot on OpenAI / AWS Bedrock. Deploys go out through GitHub Actions to S3 and CloudFront.

WHAT I BUILT

Shared web & mobile

Angular + Capacitor with PrimeNG and Tailwind. One app surface for web and mobile, maintained with the team.

Dashboards & ops screens

Reporting and day-to-day tools used in energy workflows, mainly around TAURON.

AI chat in the product

Chatbot features hooked up to OpenAI and Bedrock — not a demo, something users actually open.

Release pipeline

GitHub Actions → S3 + CloudFront, so builds land without a manual dance.
