DAMIAN MILEWSKI

00 Node.js · TypeScript · Angular developer

I build web applications
and system integrations
that can keep growing.

I help companies, software houses and startups ship software — from architecture design through to deployment.

Let's talk about your project See what I can do

01 Clients

Who I work with

  • 01 Small and medium companies processes · integrations · tools

    A manual process eats your team's time, or your systems do not exchange data. We talk about the business problem, not the technology.

  • 02 Software houses senior · separate module

    I step into an existing codebase, follow your standards and deliver tests and documentation alongside the code.

  • 03 Startups first version · validation

    I build the first version so that after validation you can keep developing it instead of starting from scratch.

02 Services

What I can do for you

  • 01 Web applications Angular · NestJS · PostgreSQL

    Admin panels, internal systems and customer-facing applications — from architecture to deployment.

  • 02 System integrations REST · SOAP · OAuth2 · RabbitMQ

    Payments, CRM, ERP, partner services. Authentication, data mapping, error handling and retries.

  • 03 Backend and architecture Node.js · NestJS · Redis · BullMQ

    Module boundaries, queues, caching, query performance. Code your team can change without fear.

  • 04 Deployment and DevOps Docker · GitLab CI/CD · nginx

    Containers, pipelines and reproducible environments. Releasing stops being an event.

  • 05 Application modernisation C#/.NET · TypeScript · Node.js

    Moving legacy applications step by step, without stopping the system that is running.

03 How I work

Predictably, stage by stage

  1. 01

    Conversation

    I learn the problem, the goal and the constraints. You check whether I am the right person.

  2. 02

    Scope and quote

    You get the work split into stages, with a quote. You know what you pay for and when you see results.

  3. 03

    Delivery

    Short iterations. After each stage you see working software, not a progress report.

  4. 04

    Deployment

    I deploy, hand over documentation and stay available once the system runs on real data.

04 About
