As a performance creative specialist with 9+ years in design and 3+ years in performance marketing, I produce video & static ads engineered to stop the scroll and drive installs - tested by CTR, IPM, and ROAS, and backed by ASO so the users I bring actually convert. Design that's measured, not just admired.
I bridge organic growth (ASO) and paid acquisition (UA), combining player psychology, performance data, and strong visuals to maximize visibility, conversion rate, and downloads.
WHAT I DO
App Store Optimization (ASO)
- Keyword research and metadata optimization for the App Store and Google Play
- Conversion Rate Optimization (CRO) and A/B testing of store listings
- Creative design of storefront assets: app icons, screenshots, feature graphics, and app preview videos
- Hands-on in App Store Connect and Google Play Console
- Localization of store creatives for global markets
User Acquisition (UA) Creatives
- High-performing video and static ads for Meta (Facebook/Instagram), Google Ads, TikTok, Unity Ads, AppLovin, IronSource, Mintegral, and Apple Search Ads (ASA)
- Hook-driven concepts built around audience motivation and tested by CTR, IPM, and ROAS
- Motion design and editing across 9:16, 16:9, and 1:1 formats with full network safe-zone compliance
- Competitor and Ad Library research to find winning angles, then iterate on winners and cut losers
Creative Strategy & Testing
- Creative briefs built around clear, strategic hypotheses
- Structured creative testing and performance analysis - why a creative worked, why it failed, and what to test next
- Turning customer insights and player psychology into concepts that convert
Branding & Visual Identity
- Logos and full brand identity systems
- Esports apparel and jersey/kit design
- Livestream and Twitch overlays, plus social media layouts for teams and studios
TOOLS
- Adobe Photoshop, Illustrator, After Effects, and Premiere Pro
- Figma
- GenAI tools
- SensorTower
- AppsFlyer
WHO I WORK WITH & RESULTS
I've produced creatives and managed ASO for studios like Battle Creek Games, GamoVation, Voodoo, Applica Agency, across casual, hybrid-casual, and puzzle titles, but not limited to mobile apps. Highlights include scaling marketing ad spend to 6 figures, hitting ~18% CTR on UA video creatives, and crafting designs for 250+ clients across multiple industries.
HOW I WORK
I work on a B2B basis and I'm comfortable starting part-time and flexible before scaling into an ongoing engagement. I'm also happy to begin with a paid test task so we can confirm we're aligned before committing to bigger work.
Whether you're rebranding, launching a new title, or scaling a game or app globally, I bring creativity backed by performance.
Send me your store listing or game link and I'll point out a few quick wins I'd test first.

Ecommerce · Performance Marketing · Brand Building
I'm an ecommerce operator and performance marketer with over 3 years of hands-on experience across the entire commercial stack, from paid media and creative production to funnel optimization, brand building, and product development. I've worked every side of an ecommerce business: as a freelancer doing different types of jobs, as the manager holding cross-functional teams together, and as a founder who has built brands and products from a blank page all the way to sold-out launches. My strength is that I understand how the pieces connect. I can research a customer, shape the angle, write the script, produce the creative, run the ads, fix the funnel, and read the analytics, without needing a separate specialist at every step. I'm equally comfortable working inside established SOPs or building the process myself where none exists.
Above all, I genuinely enjoy and love ecommerce and digital marketing, and I'm always looking to learn more and grow, staying open to new tools, methods, and practices as the field keeps evolving. I'm kind and easy to work with, communicative and open, proactive and self-motivated, and I stay positive and level-headed under pressure. I enjoy working as part of a team, but I'm equally effective on my own. Outside of work, I keep a healthy and active lifestyle. The gym, boxing, and physical activity are my main hobbies, and I don't smoke or have any problems with alcohol.
Core skills:
- Advanced Meta Ads - full campaign structure, creative testing, scaling and troubleshooting, with hands-on experience managing budgets of up to $10,000 per day
- Basic Google Ads - search campaign setup and management
- Static and video ads from scratch - built end to end, from concept and script through to the final edit
- AI image and video generation - producing ad creative and content using modern AI tools.
- Copywriting and scripting - for ads, landing pages, and video, written to match the customer and the angle
- Creative strategy and direction - ad creative, UGC, content, and video ad strategy, plus creative direction and product photography direction, including briefing creators and agencies for video shoots
- CRO and landing page building - improving conversion rates and tightening funnels across the customer journey
- Full Shopify knowledge - deep working command of the platform and its app ecosystem
Page builders - GemPages and PageFly
- Customer research - building avatars, angles, and concepts that drive creative and messaging
- Market research and product-market fit - finding product-market fit through market research and competitor analysis
- Product sourcing and development - from finding suppliers to shaping the product itself
- Analytics and performance analysis - reading the data to guide scaling and optimization decisions
- Claude for marketing - Cowork, Skills, and Automations to speed up research, creative, and operations
- Up to date with AI - actively following and learning new AI tools, and keeping current with developments across the AI world
- Basic email marketing
- Design and editing tools - Canva, Figma, and CapCut
- Tooling - comfortable with most task management and team communication apps
Ways of working
- Team management and cross-team communication
- Reliable, responsible, and always on time
- Quick learner who's highly adaptive
- Able to work with or without SOPs
- Strong communicator who's always ready to learn more
