The Genesis

Two engineers.
One goal.

We started CZ Dev because we kept seeing the same problem: founders with real workflows stuck using tools built for someone else.

Two founders in discussion

“Software should be a silent partner, not a noisy obstacle.”

Precision Engineering

Every line of code is written with the same care an architect gives to a load-bearing wall.

brush

Editorial Design

We believe software should be as beautiful as a high-end journal. Sophisticated, quiet, and intentional.

Direct Partnership

No project managers. No middlemen. You work directly with the builders of your vision.

Tamas Czaban

Co-Founder & Backend Engineer

location_onBudapest, HU

Tamas leads the Python backend, data layer, and security review at CZ Dev. Day job: vulnerability threat management analyst at Citi, where he built the GEM Dashboard in two months, shipped the Firewall and Load Balancer Vulnerability Dashboard solo, and wrote the email composer that cleared Apache Tika XXE and Oracle HTTP Server RCE L0 incidents inside their 48-hour windows, replacing a 4-hour manual mail-merge with a 12-minute pipeline. Before Citi: on-call for critical OpenStack infrastructure at Ericsson (95% on-time delivery, 90% queue utilization on concurrent cases) and reporting under intra-day SLAs at BlackRock (200+ daily reports, 30% direct ticket reduction). At CZ Dev he ships VitalRegistry v1 and v2, KEV Explorer, and Advisory Composer, and leads security review across the portfolio. Stack: Python, TypeScript/React, Firebase. BSc in Business IT, Budapest Business School.

location_onKecskemét, HU

Zsombor owns the React frontend, UX, and visual system at CZ Dev, and shares the Go and TypeScript backend with Tamas. Three years of full-stack enterprise: at GE Healthcare he was one of three core engineers taking a Customer Onboarding Tool from proof-of-concept to Milestone 1, building on a Go backend and TypeScript/React frontend with REST API integrations. Before that: Taboola's e-commerce recommendation stack and 1.5 years as a Junior ServiceNow Developer at BitKnights. CZ Dev is his second B2B SaaS launched from scratch, shipped in 5.5 months with two pilots and a mid-flight frontend framework change. Pursuing an MSc in ICT Innovation across Aalto University and the University of the Aegean, with a minor in Entrepreneurship. BSc in Computer Science, ELTE University. Stack: Go, TypeScript, React, Python, Docker, Kubernetes, AWS.

Philosophy

Foundational
Ethics

Engineering with intent means building on a foundation of clarity, ownership, and precision. We reject the ephemeral in favor of the enduring.

A lone fisherman in a canoe on still backwater at first light

Structure determines destiny.

Every line of code is a brick in a digital legacy. We treat technical debt as a moral failure.

lock_open

You own the code

No vendor lock-in. Every line we write is delivered with full IP rights. Your infrastructure should be your sovereign territory.

Ownership
architecture

Small is sharp

Senior-only squads. Avoiding the bloat of large agencies. We favor surgical precision over brute force headcount.

Intentional Architecture

We build for longevity, not trends. We choose boring technology that works reliably over the hype of the month.

Longevity
visibility

Radical Transparency

From budget allocation to git commits. You see what we see. No mirrors, no smoke, just engineering truth.

Truth

How an engagement works

Most projects start with a single call and ship within 4–8 weeks.

Architecture is destiny

“Engineering is not just code; it is the curation of logic into art.”
