Which started out in 2016 as a personal weekend hack, by now it became the home of hundreds of uprising music artists creating something different each day.

The remixes, mashups, bootlegs and hip-hop disses created a both culturally diverse music platform and also an opportunity for myself to understand and connect better with the music industry.

Through the process I’ve learned a lot from the technical side, but also about product development, marketing, SEO just to mention a few.

Although the web app didn’t reach yet its limits, this year something very new might come to remixmonsta related to decentralization.

Households are responsible for the largest portion of all food waste. According to data, approximately 40 to 50 percent of food waste happens at the level of the consumer, and I was one of them.

With a friend of mine we decided to take action and through research, experiments and design thinking came to a conclusion to create a habit-forming app which helps to combine ingredients from the fridge to reduce the waste and make delicious meals.

We’ve received positive feedback from the people, although we quickly realized our efforts are tiny in comparison to how complex and big problem itself, so we’ve parked the idea for a while.

YData helps data scientists that struggle with the access to sensitive data and poor data quality while having to build and deploy scalable AI solutions.

Their innovational solutions as a startup required a professional look on the market, but we didn’t just create the branding for them, but also established a fresh user experience for the platform which solves the data pains with synthetic data and tools that improve data quality in an automated way.

Since then Data grows steadily into more territories and industries, check out their efforts for the better future on their landing page we’ve created.

There is something special about the feel of the paper. Sometimes it’s so good to get disconnected from screens and ideate with a brush pen and just enjoy the process.

Although my work is mainly seen on digital interfaces, I’m not afraid to start the exploration in a more natural environment. This image was made when I created some textures for an upcoming article about illustration. No animal was harmed.

Started out as a simple spreadsheet to help control my mom’s impulse buying behavior, which later gave the idea to create a web app from scratch to help anyone willing to reduce the money wasted on unnecessary items.

The aim of the product is to create the same dopamine effect by uploading a product the user didn’t buy and then getting rewarded by random amount of ◆ for the efforts. The built-in inventory also helps them as a reminder what they already own, before falling into the trap of advertising or social pressure.

It was a helpful extension of other budgeting solutions on the market, but never really reached the native app phase due to high financial license fees.

#Product Design

Design systems are the heart of big design organizations, which brings speed and efficiency in the day to day from native apps to digital retail.

Through the years of working within the team with talented folks, I had a chance to be involved in setting up UI toolkits, migration from Sketch to Figma, scalable localizations, building analytical dashboards, theming with tokens and translate the overall brand image into digital just to name a few.

adidas being a top creator sports brand was actively looking for influential personalities from other areas to collaborate. The work with Beyonce and her team started in 2019, and from 2020 I had a chance to be contributing member of these campaigns from a digital design perspective.

The core of my responsibility was to translate the Ivy Park team’s request into designs, which built with the limitations of the existing adidas ecosystem to create a smooth end shopper experience from tease till finish.

Due to the COVID-19 pandemic a lot of things became difficult, including fitness. Being closed down into our apartments created a new challenge to be still on the top of our workouts.

Beyobe picked up the issue by creating a native application, where certified instructors and machine learning technology helps you to do your exercises accurately and regularly.

The challenges and the influencer-system was another answer to a tangible social phenomenon too.

For the pre-seed round the startup asked from me a pitch deck for investors, but also an inviting landing page for their future customers.

Throughout my product design journey I’ve realized I tend to rely on the same steps to run my projects smooth, and when I ignore them …well it usually ends up in chaos and regret later.

These are not linear steps and often the missing information or the async nature of the work requires to shuffle them, but the steps still remain the same.

Identify what the business wants

Let’s be realistic, business are running based on some kind of performance indicators with a revenue amount attached to it. For this reason it’s critical to explore it to create focus and constraints (constraints are good!).

My explorations consist of the current value proposition, the competitive analysis by highlighting the business advantage and the measurement of success for the project. All aligned with the stakeholders to avoid potential misunderstandings.

Identify what the users (might) want

Unless I’m delivering designs for the future robots of Mars, there is a human being I need to take into account.

I like to create a hypothetical list of things about their needs, by using Strategyzer’s value proposition design methodology and quantitative and qualitative research to imagine the world, the audience is “living in”.

Who is the target audience?

It’s strongly related to the previous step, but this time going out on the field by talking with actual people online or offline to validate my presumptions about them. I’m not a fan of made up personas and empathy maps, so I like to be as real as possible and gather my own data.

Ideation of potential solutions

At this stage of the process I focus on idea generation with different tools (crazy8, mind mapping, etc.) and get tons of really loose sketchy ideas. My focus is on empowering the user to accomplish their goal in the most efficient, effective and delightful manner as possible.

This is usually a time when I connect back to colleagues and stakeholders to check various attributes (technical and other feasibility, scalability, budget etc.) about each of the ideas and prioritize.

Build a prototype

Depending on the lifecycle of the product and the aim of the project, I match the fidelity of the prototype. It has to be quickly to build and easy to share with the right audience. The lower the fidelity the harder it will be for people understand so it’s always a bit of balancing the expectations.

Test the hell out of it

I’m a huge fan of the fail fast mentality, so I try to eliminate all the “not good enough” ideas to go further with the right prospects through user testing and A/B testing.

For me this is the most exciting part, seeing people doing completely different things from what was expected. The number of tests required is highly dependent on the scope and should be always looked at as a risk reducer from future flops.

Iterate, iterate and iterate

Based on the received user feedback, it’s important to rank what needs to be refined and then go to work in that order. Then, test it. Refine it. Test it again relentlessly. The goal here should be to align with the user’s mental model as much as possible and get the proof it’s also moving up the bottom line of the business.

Ship it

It’s time to publish the winner out in the world so the designs have to clean and tidy as possible. To collaborate with developers the best, I tend to do everything in Figma, but regardless of the tool ultimately the goal is to find the easiest way for handover possible. At the ideation phase they’ve been hopefully already involved, so the potential obstacles been cleared.

Measure the performance and improve

It might seem like it’s the end, but it’s just the beginning. It’s important to check the analytics of any kind, to see how the idea performs in real context with larger amount of users. Often the results are delayed in time but in the end I want to make sure both the business requirements and the user needs are solved and potentially watch out for other new improvement possibilities to start the cycle again.

Project Graveyard


A curated Twitter feed for junior UX professionals to find opportunities quicker. Turned out not the amount of positions are the real problem.



Food waste was a greater issue than us, and quickly realized we can't be present all the time building the community as it should be.



Although this idea even went through the Y Combinator startup school program, and also got traction by the audience, the technical limitations and the highly regulated financial market was a blocker to continue.


Your Startup Will Die

Based on Daniel Kahmnemann's premortem thesis it seemed like a good idea to collect experience from failed startups to prevent future ones. Didn't got enough traction to continue.


Never Have I Ever

Interactive drinking game with your crew. Seemed like a good idea, but got a little too dirty after some AI hooked into it, so it was better to turn down.




As a tool

Thanks to my curiosity I’ve realized early most of my imagination is achievable with the combination of design and code to share with other people.

I consider myself self-taught, but out of all the resources out there I would definitely highlight Treehouse and SuperHi, which both helped tremendously through my journey.

Cover image of Peter Javorkai's twitch stream


I started doing streams in 2018 to get better at coding, and at first I was doing short 1-hour sessions challenging myself through Front-end development projects governed by Frontloops. Shame on me, I'm quite inactive since that series, but hopefully the world is waiting for my glorious return some day.

Techrunch Disrupt Hackathon 2016


These events are short circuit collaboration challenges around a theme, where people by using code, data, design and many other disciplines create something hopefully awesome within the given time limit.

By far these are my favorite places to get to know new people and also get tested our group minds to see if we can take on the challenge, and I really recommend to everyone to try it at once. Be careful youcan get addicted. Upcoming hackathons here.

Due to sheer luck I met a couple of amazing people @Techcrunch's Hackathon in London, which we won in the developing world category.
