Jakub Čech — Custom Software Development

Services

What I can build for you

Whatever we build, I can cover the whole development cycle — analysis and scoping, implementation, production delivery, DevOps, monitoring, and long-term maintenance.

MVP and new products

From idea to a working product your first users can try. Together we trim the scope to what really matters, ship an early version, and iterate on real feedback. Production-ready from day one — CI/CD, monitoring, and a foundation that can grow with the product.

Backend & integrations

Reliable backend services that scale, built in Kotlin, Java, or Python. I connect the systems you already use — CRM, ERP, payments, third-party services — or expose your data through a clean, well-documented API.

Company websites

A fast, polished website that presents your company and turns visitors into inquiries — designed, built, and deployed.

Custom internal company applications

Tools tailored to how your company actually works — replacing spreadsheets and manual processes with software that fits.

AI integration & tooling

Bring AI into your product or internal workflows — practical automation that saves hours, not demos that impress once.

How I work

One process from idea to production — and beyond

We agree on what gets built before a single line of code. Then I deliver it — and keep it running.

Free intro call

You tell me what you need. I ask questions and tell you honestly whether I'm the right fit.

Analysis & scope

I dig into the problem first, write up exactly what I'll deliver, and prepare a proposal with a fixed price and a clear scope.

Build in the open

Milestone demos of working software and regular syncs. You see progress at every step, not just at the end.

Launch & operate

Deployed to production with CI/CD and monitoring in place. I handle the DevOps and ongoing maintenance to keep it healthy long-term.

Past work

Projects I've helped build

Contexi

2023 — now

Built the software side of a DNA-analysis company from zero — the web application, internal apps, backend services, and the infrastructure they run on. Architecture, DevOps, releases, and production monitoring, end to end.

Greenfield buildFull ownership

Whalebooks

2020 — 2023

Took over an existing product as lead engineer: shipped new features, kept it stable, and migrated the whole system to a modern technology stack without disrupting users.

RIXO

2019 — 2020

Designed and delivered several backend microservices for a system serving real customers — most notably an OCR service for automated data extraction from documents, and a Salesforce integration service.

2018 — 2019

Part of the team behind the high-throughput ad-delivery backend at one of the largest Czech internet companies — Kotlin services pushing thousands of ads per second to the Czech internet.

ČSOB

2017

Helped develop corporate internet banking for one of the largest Czech banks — software where reliability and security are non-negotiable.

Cleverlance

2013 — 2016

Early in my career, helped develop a telco billing platform — the system that turns calls, data usage, and tariffs into accurate customer invoices — used by multiple telco operators. Complex domain logic, high data volumes, and zero tolerance for billing errors.

About

Who you'll work with

I'm Jakub Čech, a software engineer based in Prague. I started out in enterprise software — banking, telco, high-traffic ad systems — where reliability isn't optional. Today I bring that same rigor to smaller, faster-moving projects where I own the result end to end.

Above all, I build and deliver — what counts is working software that moves your business, not hours logged. I'm goal-driven: value ships early and continuously, not at the end of the project. And you'll always get an honest answer from me, even when it's not the one you'd like to hear.

Why me?

13+ years building production systems.
From analysis through development to cloud and operations.
I don't start coding until it's clear what we're delivering.
No account manager between you and the developer.
