PASSION FOR PROGRAMMING

CAN DO

My name is Cezary Siwa and I believe
that quality of my work should never be compromised.

About Me

I'm a web programmer with over 10 years of commercial experience. My first job was PHP programming for Actinet.pl and my main responsibility was integration layouts delivered by a designer with company's bespoken CMS solution. For a next 5 years I worked for several digital agencies in Poland like GoldenSubmarine, RedExperts or Playsoft. Most of my work was related to web development, the skills I learnt during these days was PHP, HTML, CSS and JavaScript.

After that I became a full time freelancer on UpWork platform. I specialise in Wordpress themes and plugins development. I also created a few plugins for CodeCanyon, which is quite a challenge due to standards they have and verification process. I love to be proud of the work I do, this is why I always put an extra effort to make the project even better. There is always a way to make things better: additional cool effect, making the website load faster or use less bandwidth, optimisation of the pictures. That's what I do, raising the standards each time.

Skills

Wordpress

Wordpress

Most of the projects I do are Wordpress related. I create custom themes from scratch and also a plugins. I use minimal amount of plugins to increase the performance. Typical website I do has ACF plugin for custom fields, Contact Form 7 or Gravity Forms or Formidable to handle contact form submission and that's all what we need! To make the website multilang, I use WPML or Polylang, and if you need ecommerce, I'll use WooCommerce.

I use Bootstrap for CSS, to make the website responsive and perfect on all browsers. jQuery is the JS library I use in Wordpress projects. I merge CSS and JS files to reduce the number of requests and make the website load faster. Theme's pictures are optimised with tinypic.

After 5 years if intense Wordpress development I produced my own way and standards which are very liked by my clients (see testimonials below).

PHP

php

It's impossible to know Wordpress without PHP. Before I became a Wordpress specialist, I developed custom PHP solutions.

I used many PHP frameworks like Symphony, Kohana, CakePHP or Laravel (and this one seems to be the best). Apart from bespoken CMS solutions, I developed many tools for image processing, web crawlers or XLS/DOC/PDF generation.

Node.JS

Node.js

Node.JS is a super fast backend solution, it's very often used as backend for mobile apps or React/Angular/Vue.JS frontend apps.

With Express.js we can create easily and fast RESTful API endpoint, Socket.io gives us real-time engine, works perfectly with Node.

I did a few projects with Node and I keep on looking for more, I believe it will become more popular in near future.

Mobile Apps

Mobile Apps

I develop mobile apps for both iOS and Android platforms. I know native solution for Android (java) and hybrid for both (React Native, Cordova).

A few of my apps has been accepted my marketplaces so I know the process.

React.js

React

React is a modern frontend JS library designed to develop one page apps and interfaces. It runs very smooth and gives an impression like if we're using an app, not a website.

I tried a few frontend frameworks like Angular or Vue.JS and in my opinion React seems to be the best due to performance and learning curve. It also seems to be the most popular.

Portfolio

AppToolTester

The scope of this project was to translate the designs delivered by a client into fully responsive custom Wordpress theme. The theme contains many page templates to handle required functionalities. There are two types of apps comparison pages, the app review page was also quite a challenge. Content edition is possible via custom fields created with ACF.

Technology: HTML, CSS, Wordpress, WPML, ACF

Collabary

This was another successful design 2 Wordpress transition. Once again the design was delivered by a client and my job was to create custom theme. Creating a nice administration zone and responsive HTML/CSS was not the only task, there was a few animations to implement as well.

Technology: HTML, CSS, Wordpress, ACF

Preventing Food Waste

It was a pleasure to integrate this nice and clean design (delivered by a client) as a Wordpress theme. This time there were requested extra animations which made the website vivid and delightful.

Technology: HTML, CSS, Wordpress, ACF

Aneden Consulting

Modern, one page company website - just like mine. There are just 4 sections, but the layout is adjusting to the size of your screen. The main reason why I don't want to go back in time is because we didn't had CCS3 back then. This website looks simple, but wouldn't be created few years ago.

Technology: HTML, CSS, Wordpress, ACF

Premier SOS

Wordpress websites is not the only thing I do. This time I did a native Android app which gives quick and easy access to the emergency contact details and medical info of participants. The app basically gets the data via API and displays it to the user. Simple, but very nice position in my portfolio.

Technology: Java, Native Android

Zone7

This is an another example of successful design 2 Wordpress transition. Apart from stuff I do everyday: perfect PSD 2 HTML/CSS transition, custom fields to manage the content, responsiveness, this website has slanted lines in the layout. I did them with pure CSS, which minimised the amount of pictures used by the theme.

Technology: HTML, CSS, Wordpress, ACF

Equova

Client delivered me this modern and clean design to integrate it with Wordpress. This one required many new CSS3 solutions like flexbox, transforms and also some animations. All parts of the website are easily editable with custom fields system I created.

Technology: HTML, CSS, Wordpress, ACF

Leung Gallery

Bilingual art gallery website. Client delivered me a very modern and clean design to implement it with Wordpress. The website has many effects and modern CSS3 solutions. Flexible and intuitive admin zone was made with ACF plugin and build-in Wordpress functionalities like custom post types and taxonomies.

Technology: HTML, CSS, Wordpress, ACF, Polylang

Cezary helped me a lot on the job i had assigned to him, being patience and working precisely also in an uncomfortable situation: situation not created from him or our part. Cezary skills are strong, and he is really present and helpful in every part of the job. I really recommend Cezary: great job! Claudio Bizzotto
From the outset Cezary was knowledgeable and highly professional. I'm sure we'll work together in future WP projects. I would hire him again in a heartbeat. Outstanding! Tom Edmonds
Cezary has been extremely flexible and accommodating on these two complex custom Wordpress builds. He is professional, lightening-fast and delivered the sites to a very high standard, well before their deadline. He was then kind and considerate fitting us in to his schedule, when, due to client delays with final content we had a considerable wait before finishing the projects. Can't recommend him enough and will be hiring him again for future projects. Thanks Cezary. Rosa van Wyk
Once again I am very satisfied with Cezary's work. He always works seriously and the communication is very good. Aude Ahsein
Cezary does great coding work and always completes tasks on-time or ahead of schedule! Savanna Mauldin
Cezary completed the Wordpress website faster than expected with no issues at all. We'll definitely use Cezary for future work. Dane Gorton
Great working with Cezary again. Fast, efficient, great communication (thorough) and clean code. Highly recommend. Lynan Saperstein
Cezary delivered good work on this custom WP development of 5 websites which included custom post type and taxonomy, creation of custom trip filters, etc.

His communication was clear and his skills and knowledge are very strong. We had new challenges and tweaks along the way and Cezary made it easy to work out new milestones and extra payments.

We have enjoyed working with Cezary again and will definitely have additional jobs for him in the future. Highly recommended.

Since March 2013 I do projects on UpWork (formerly oDesk) platform. Most of my projects are Wordpress-related, however I also did many mobile apps (native Android and hybrid), Node.JS backends, websites based on PHP frameworks and so on. Doing projects on UpWork is always fun and requires can-do attitude, because each job requires different technology and approach.

After 5 years I accomplished over 900 jobs for over 300 different clients!

Don't hesitate to hire me on UpWork if you also have an account.
