Product Design - Studiofy X Webflow Template

UI/UX Design

My design approach follows a step-by-step process—though not always in order—tailored to understanding multiple stakeholders and crafting seamless user experiences. I start by building a customer profile, mapping the user journey, and brainstorming ideas. From there, I move into sketching, scrappy wireframing, prototyping, and running design sprints to test usability and concepts.

I focus on designing intuitive interfaces that are both visually appealing and easy to navigate, ensuring a smooth and satisfying user experience—yet always aligned with business goals.
Beyond aesthetics, I measure success through key metrics like Feature Adoption Rate, User Engagement Metrics, Customer Retention Rate, and Net Promoter Score (NPS) to ensure designs drive real impact.

Whether it’s a website, mobile app, or digital product, my goal is to create user-friendly layouts that boost engagement and conversions. If you’re launching something new or refining an existing product, I’m here to help.

Product Design

My product design approach is centered on understanding user needs, spotting market opportunities, and crafting innovative solutions that address real problems. I design products that are not only visually compelling but also highly functional, intuitive, and aligned with business goals. By leveraging the newest technologies and optimizing resources — time, budget, and team efforts— I ensure efficiency without compromising quality. From conceptualizing new products to refining existing ones or designing for an entire product line, I focus on creating solutions that enhance the user experience while maximizing impact. No matter the stage of your product, I’m committed to delivering exceptional, future-ready results.

UX Research - Studiofy X Webflow Template

UX Research

I employ a range of methodologies to gain insights into user behaviors, needs, and motivations. Whether you're a startup looking to understand your user base, or an established company aiming to enhance your digital products, my UX research can provide the data-driven foundation for effective design decisions.

Web Design - Studiofy X Webflow Template

Web Design & No-code programming

I leverage Web Design & No-Code Programming to create, refine, and optimize digital experiences that are both visually compelling and highly functional. Whether you have a scrappy landing page or a highly ineffective one, I’m here to analyze, improve, and even build from the ground up. By combining modern design principles, no-code tools, and strategic methodologies, I ensure your website not only looks great but also drives engagement, conversions, and business success—all while saving time, resources, and development costs.

Branding - Studiofy X Webflow Template

Branding

My approach to branding & rebranding blends an in-depth understanding of your business, creative strategy, and engaging design to build a powerful and authentic brand identity. My services include brand strategy, identity design, brand voice development, brand collateral design, and brand guideline creation.

Whether you’re a startup establishing your identity or an existing brand in need of a refresh, I craft cohesive, memorable, and impactful brand experiences that resonate with your audience and align with your business goals. If you’re looking to create or redefine your brand, I’m here to bring your vision to life.

Graphic Design - Studiofy X Webflow Template

Graphic Design

I harness the power of color, typography, imagery, and layout to design visuals that captivate audiences and strengthen brand messaging. Beyond aesthetics, I apply design heuristics to ensure clarity, usability, and strategic impact. My expertise extends to creating high-converting ads, manipulating images, and crafting visuals optimized for various platforms—whether for digital or print.

From logos and marketing collateral to social media graphics and ad creatives, I design with both engagement and functionality in mind. Whether you’re a startup building a strong visual identity or an established brand ensuring consistency across marketing efforts, I deliver designs that not only look great but also drive results.

The name "Pixelheart" combines two elements that are fundamental to my work and philosophy.

"Pixel" represents the smallest unit of a digital image or graphic, a nod to my attention to detail and commitment to quality in the digital design realm.

The "heart" signifies my passion, dedication, and the human-centric approach I take in my work.

Together, "Pixelheart" reflects my mission to create digital designs that not only look good to the eye, but also touch the heart and resonate with your audience.

My design journey: From a spark to impact
 

Explore my three-step design process.

01

Discovery & Research

This is the foundation of my design process. I begin by understanding your business, goals, and audience to determine how I can help. With AI systems, structured processes, inspirational sources, tools, and ideas, I gather and analyze data to uncover valuable insights. This guides my design decisions and helps create the best plan moving forward.

02

Concept & Design

Based on my research, I craft a unique design strategy tailored to your needs. I blend insights, experience, human creativity, AI precision, and powerful design tools to create compelling visuals that truly resonate with your audience. My focus is on functionality, a minimalistic yet captivating aesthetic, and a seamless user experience — all while ensuring your business achieves its goals without compromising my core values.

03

Iteration, Delivery & Measure

Something always happens — that’s why I stay agile. Plans evolve, and I adapt while staying focused on the goal. Once the initial design is complete, we review and refine it using AI, online tools, study groups, user testing, and concept validation. Through multiple iterations and your final approval, I deliver a design solution that makes you say, “Phew, you’ve got my back.” This approach ensures a product that truly reflects your vision and resonates at its core.

04

Communication & Teamwork

Oops, I meant 4 steps. I believe great design is built on strong communication and teamwork. Transparency, open discussions, and continuous feedback create a space where ideas flow, evolve, and improve. I actively listen, challenge assumptions, and refine concepts together with you, ensuring every decision aligns with the bigger picture while maintaining autonomy. Just like a united team can move mountains—“Сговорна дружина планина повдига”—our collaboration turns challenges into opportunities, making the end result not just good, but truly impactful.

Emil Atanasov

Lyubo is very passionate about what he does and is always full of ideas. After every creative meeting with him, I feel more energized. He's also very organized (which I'm not), responsible, kind, thoughtful, easy to get along with and always ready to help.

Veselin Tonov

Founder & CEO | Epic Media Group

Lyubomir Kolev did absolutely excellent work for us. We appreciate the extra time and effort he spent getting the logo the way we wanted it, taking in consideration every feedback we had. I will definitely promote his services to others in need and will continue to work with him on our future projects. Thanks, Lyubomir!

Spas Biyarski

Co-founder & CEO | Codeworks

The design service, that Lyubo, gave me was excellent. We discussed every aspect - from that what interests and preferences I have to the smallest detail of my work and the direction right now, in which I want to develop. There were made a couple of designs of logos and business cards till the point we decided, which best represent me as a specialist. I want to add that the process is happening fast and reliably - after I go new idea the design modification took around a day or two and for sure, that wasn’t easy.

Slavi Vladikov

& Influencer

I can give only a positive feedback for my work with Lyubomir. He took care of the design education process and did not understimate me for once. He showed me the right way of designing without taking my room of making mistakes and learn a lot from them. For me, it was a pleasure working with him. He is not only a mentor, but also a friend. :)
