Your copy is either making you money or costing you money.
There's no middle ground.
The ad that almost converts, the email that gets opened but never clicked, the sales page people read halfway through and abandon…
They're not just underperforming. They're bleeding revenue that should already be yours.
The problem usually isn't the product. It's the words wrapped around it.
Hi, I'm Stoyan.
I write direct response copy for businesses that are done leaving money on the table…
The kind of copy that grabs attention, builds desire, and makes buying feel like the natural next step.
Here's what I can help you with:
Sales Page & Sales Letter Copywriting
Landing Page Copywriting & Funnel Copy
Facebook Ads, Google Ads & Social Media Ad Copy
Email Copywriting & Email Marketing Sequences
VSL Scripts & Video Sales Letter Copywriting
Webinar Scripts & Presentation Copy
Website Copywriting
Direct Response Copywriting
Social Media Copywriting & Caption Writing
Article Writing, Blog Writing & SEO Content Writing
Product Descriptions & E-commerce Copy
And if you need content rather than conversion copy - articles, blog posts, SEO pieces - I can take care of that too.
One more thing worth knowing: I'm new to Upwork.
Before you scroll past - that's actually a good thing for you.
I'm not here to coast on past reviews. I'm here to build a reputation, which means every project I take right now gets treated like the most important one on my list.
I read briefs twice, ask the questions other writers skip, and don't hand anything over until I'm genuinely proud of it.
You won't get copy that's technically fine and quietly forgettable.
Check out my portfolio below and see if my writing style fits what you're building.
If it does, send me a message.
Cheers,
Stoyan

UX/UI & Web designer with 3 years of experience, blending system thinking with
hands-on collaboration. I design digital products that make sense for both users and
the business from the first brief to the final developer handoff.
I'm comfortable taking ownership, working directly with clients, and turning complex
ideas from stakeholders and teammates into clear, consistent design systems that
ship fast and scale well. I enjoy tackling challenges together with teams just as much
as working independently, keeping things organized, measurable, and human.

I specialize in slot game backend systems, simulation pipelines, and game math optimization.
With 8+ years in the gaming industry, I help studios and indie developers design and build robust, scalable slot game systems - from backend architecture, to math models, gameplay and performance optimization.
Systems & Backend Consulting:
Slot engine architecture (backend logic & RNG flow)
Simulation pipelines (scalable Monte Carlo setups)
Performance optimization for large-scale simulations
Data flow design and result validation
Tooling for faster iteration and balancing
I can analyze your existing system and provide clear, actionable feedback on how to improve performance, scalability, and reliability. If you’re building a game from scratch, I can design a complete backend structure - ensuring it is efficient, maintainable, and production-ready.
Game Math & Design:
RTP calculation and breakdown
Volatility analysis and tuning
Feature and bonus balancing
Monte Carlo simulations (large-scale statistical validation)

Identifying issues in existing game mechanics
I combine hands-on experience in game production with a strong technical background, allowing me to bridge the gap between backend systems, math, and game design.

What you can expect:
Clear, actionable reports
Data-driven recommendations
Fast and reliable communication
Practical, production-ready solutions
If you’re building or improving a slot or probability-based game — and need both a solid backend foundation and reliable math behind it — I can help.
