You need a video that actually sells — not just looks good.
I produce cinematic AI-generated videos for brands, startups, and creators — end-to-end, from concept to final delivery. Whether you need a medical explainer, a product launch video, a brand film, or an athlete highlight reel — I handle the full production: AI video generation, motion graphics, voiceover, music, and editing.
My background in QA means every frame is intentional. No random generations — I use structured prompting, iterative refinement, and careful review on every output before it reaches you.
What I deliver:
AI Video Ads · Cinematic Brand Films · Explainer Videos · Medical & Healthcare Video Production · B2B Corporate Videos · Product Launch Videos · Kickstarter Campaign Videos · Beauty & Cosmetics Promos · Sports & Athlete Highlight Reels · Music Videos · AI Avatar & Lip Sync Videos · Real Estate Video · Educational & E-Learning Video · Social Media Content
Industries I work with:
Healthcare & Medical Simulation · Beauty & Cosmetics · Sports & Athletics · B2B & SaaS · Fashion & Lifestyle · Real Estate · Education & E-Learning · Music & Entertainment
My production workflow:
Concept & storyboard → AI video generation → motion graphics & animation → voiceover & music → editing & color grading → final delivery
Tools I work with:
Kling · Seedance · Runway · Midjourney · Veo3 · ElevenLabs · Adobe Premiere · CapCut · CapCut Pro
Why clients choose me:
I don't just generate — I direct. Every project starts with a clear creative brief, structured prompting strategy, and iterative refinement until the result matches your vision. My QA background means I catch what others miss — inconsistent motion, off-brand visuals, weak cuts.
If you have a brief — or just a rough idea — send an invite and we'll figure it out.

I run technical programs, the kind with multiple workstreams, external vendors, and stakeholders who don't naturally agree. Enterprise integrations, platform rollouts, transformation initiatives. 17+ years leading delivery, Executive MBA, Lean Six Sigma Green Belt.
Most project managers run a backlog. I own the outcome: scope, dependencies, risk, and the uncomfortable conversations that keep a program on schedule.
Where I add the most value:
→ Multi-team delivery — aligning engineering, compliance, client success and external partners on one date
→ System & platform integrations — enterprise-grade, spec-driven, compliance layer handled
→ Structure into chaos — taking a stalled program or an unclear roadmap and making it legible and shippable
→ Scale-up operations — building the process, reporting and governance backbone that growth requires
Recent and ongoing projects include:
🏦 Banking Integration Program — enterprise communications provider. Cross-functional delivery across engineering, compliance and client success for regulated financial institutions.
🚗 Automotive SaaS (Switzerland) — end-to-end product and delivery ownership for a fleet management platform: telemetry data modeling, vehicle diagnostics, iOS/Android.
🎓 COO / General Manager, EdTech — full operational ownership: remote ops, growth, team leadership across international markets.
✈️ Digital Transformation, German Air Force Officer School — enterprise-wide blended-learning framework, from concept to rollout.
Track record:
- Secured €500,000 in pre-seed funding by turning a technical roadmap into an investor-ready proposition
- Led enterprise-wide digital transformation inside a government/defense organization
- 10+ years as an Officer in the German Armed Forces — leading programs and teams of 150+ in multinational, high-consequence environments
- Founded InsightQuiz.de — GDPR-compliant SaaS for corporate L&D, built and shipped end to end
Methods & tools:
Agile · Scrum · Kanban · Lean Six Sigma · Multi-team coordination | Jira · Confluence · Asana · HubSpot · SAP ERP
German (native) · English (fluent) · French (basic) · CET — full overlap with EU, mornings with US East Coast
If your program has more moving parts than owners, that's the problem I solve. Send me the messy version — you'll get a plan back.

👋 Hi there! You’re here because you want your digital product to stand out — to not just look beautiful, but convert, engage, and perform. Maybe your current website isn’t delivering the results you expect — or you’re ready to bring a new SaaS or mobile product to life.
I’m Alina, a UX/UI Designer with 5+ years of experience helping businesses create products that are not simply beautiful, but functional and human-friendly. I care deeply about how people interact with technology — that’s why every design decision I make is based on research, usability, and empathy.
Whether you need a fresh SaaS dashboard, a conversion-optimized website, or a new design system, I’ll help you create a product that solves real user problems and achieves your business goals.
🧠 What I Do
🔹 Web & App Design — from wireframes to pixel-perfect visuals;
🔹 Product UX Strategy — data-driven user flow improvement;
🔹 UX Audits & Usability Testing — find friction points & optimize conversions
🔹 Responsive & Accessible Design — inclusive, adaptive interfaces;

SaaS | EdTech | FinTech | eCommerce | Digital Agencies | Startups | Corporate Websites | Travel & Hospitality | Fashion
💎 My Website Design Workflow
Creating a website is not just about visuals — it’s about strategy, structure, and storytelling. Here’s how I usually work with clients from idea to final delivery 👇
1. Analytics & Structure — I research your business and analyze competitors. I’ll discuss with you the primary goals, unique challenges of your project, target audience, current pain points, etc. Afterwards I'll create a clear site structure and moodboard.
2. Prototype — I build a detailed wireframe showing layout and functionality before final design.
3. Design — I apply visuals, colors, and content, finalize composition, and adapt for mobile.
4. Handoff — I prepare all design assets for development and assist during implementation.
✨ My goal is to create websites that look beautiful, feel intuitive, and convert visitors into clients.
