Web applications
Product-grade web apps from first commit to production: interfaces, APIs, data models, deployment and everything that keeps them running.
Software engineering consultancy
Software that ships,
built by one engineer
who stays accountable.
ET Consulting is the practice of Edin Terzic. Web applications, mobile applications and integrations — designed, built and maintained with the technology that actually fits the problem.
Services
What I take on
Mobile applications
Cross-platform and native mobile apps built to ship — offline behaviour, releases, store submissions and long-term maintenance included.
Integrations
Connecting systems that were never designed to talk: payment providers, ERPs, CRMs, third-party APIs, webhooks and data pipelines.
Engineering support
Embedded senior engineering for existing teams — code review, architecture decisions, untangling legacy code and getting stalled projects moving.

About
Edin Terzic
I'm a software engineer who works directly with the people who own the problem. No account managers, no handoffs — the person you scope the work with is the person writing the code.
Projects run in short, visible increments: you see working software early, decisions get made with real context, and nothing is hidden behind a status report. When a project ends, you get a codebase your own team can pick up.

Tell me what you're working on and what's in the way. I'll come back with an honest read on scope, timeline and whether I'm the right fit.
