Alex Tričković

CTO @ Deadline Funnel·Belgrade, Serbia

I build software that holds up in production.

I’m Alex, a hands-on CTO. I’ve spent 14 years building SaaS products, leading engineering teams, and turning product ideas into software customers rely on. These days a lot of that is AI agents, and I build them for real products, not demos.

01 Now

What I’m working on these days.

  1. Running engineering at Deadline Funnel

    I own architecture, infrastructure and product engineering across the full stack for a marketing automation SaaS.

  2. Building AI agents

    Mostly with the Vercel AI SDK: tool calling and agent workflows, in production and on side projects. I’m currently going deep on evals, observability and RAG.

  3. Engineering with AI in the loop

    I work with AI in the loop: Claude Code and Cursor, shared skills, PRD templates, and AFK + human-in-the-loop patterns.

02 How I work

Applied AI, with the responsibility left where it belongs.

Agents write code. I own it.

Claude Code and Cursor help me plan, implement and review. They make me faster, but I still read the code, question the decisions, and own the result when it ships.

Production over demos.

A demo that looks great for five minutes doesn’t interest me much. I care about systems that run in production and solve a real customer problem.

Close to the product.

I like being in the room from the first product conversation, through implementation, and into production.

Still hands-on.

I still spend my days shaping architecture, reviewing pull requests, working through product decisions, and helping a team ship.

04 Writing

Recent writing.

  1. One-piece flow for AI coding agents

    A lean manufacturing experiment with 10 envelopes, the tracer bullets idea from The Pragmatic Programmer, and the prompt I use to apply both to coding agents.

  2. Why learn to code when AI can write it?

    Generated code becomes your code when you ship it. Why reading and judging code matters more now that coding agents write so much of it.

06 Contact

Let’s build something that actually works.

I’m always up for a conversation about applied AI, SaaS engineering, or running a team that ships with agents in the loop. LinkedIn is the fastest way to reach me.
