I Take Your Idea and Make It Breathe


You describe it. I design it, code it, publish it, brand it, and market it. One creative mind handling every layer — so nothing gets lost in translation.

Flutter App Development

Your app, running flawlessly on iOS, Android, and Web — from a single codebase. I don't just write code, I craft experiences with buttery 120fps animations that make users fall in love.

UI/UX Design for Apps

Before I write a single line of code, I design every screen, every flow, every micro-interaction in high fidelity. You click through the prototype and feel your app before it even exists.

App Store & Play Store Launch

Screenshots, descriptions, keywords, metadata, review compliance — I handle the entire submission so your app goes live without a single rejection. Both stores. Zero headaches.

Backend & API Integration

Firebase, Supabase, custom REST APIs, real-time databases, authentication, cloud storage — I build the invisible engine that powers your app and makes it smart, fast, and scalable.

Website Design & Development

Premium, conversion-first websites that don't just look stunning — they sell. Every pixel placed with intent. Every headline written to persuade. Your brand's digital home, done right.

Brand Identity & Creative

Logo, color palette, typography, brand guidelines, social media kits — I create the visual identity that makes people remember you. Not generic templates. A brand that feels like you.

Facebook & Meta Ads

Full campaign architecture — pixel setup, custom audiences, lookalike targeting, retargeting, dynamic creatives. I don't run ads that waste money. I build machines that print it.

Pixel, Tracking & Funnels

Meta Pixel, Conversions API, Google Tag Manager, custom events — every touchpoint tracked with surgical precision. Then funnels that guide visitors from stranger to paying customer.

Social Media & Content

Professional page setup on Facebook, Instagram, YouTube. Content calendars, posting strategy, audience growth — I build the organic presence that feeds your paid campaigns.

App Redesign & Performance

Already have an app that feels slow, outdated, or broken? I rebuild it from the inside out — cleaner architecture, faster performance, modern design. Your app, reborn.

Admin Dashboard & Panels

Web-based control centers to manage your app's content, users, and analytics. Real-time data, role-based access, beautiful UI — built so you run your business from one screen.

Payment & Monetization

Stripe, RevenueCat, In-App Purchases for iOS & Android — I wire up the revenue engine so your app doesn't just look great, it makes money from day one.

One Vision. One Codebase.
Every Screen Alive.


Most developers build your app three times — one for iOS, one for Android, one for web. I build it once with Flutter, and it runs everywhere with native performance. Same dream, third of the budget, fraction of the time.

120fps Animations

Custom implicit and explicit animations with AnimationController and Rive.

State Management

BLoC, Provider, Riverpod — scalable architecture for any complexity level.

Backend Integration

Firebase, Supabase, REST APIs, GraphQL, and local persistence with Hive or Drift.

Platform Channels

Native module integration for hardware-specific features and platform APIs.

From Someone's Vision to the App Store

I Don't Just Build Products.
I Build the Audience That Wants Them.


A beautiful app with zero users is just code sitting on a server. I create the complete picture — the product, the brand, and the growth engine that fills it with real paying customers.

Ads That Fund Your Growth

I build full campaign architectures on Meta — custom audiences, lookalikes, retargeting, A/B tests, dynamic creatives. Not "boosted posts." Real ad systems designed so every campaign pays for itself and then some.

Precision Tracking, Zero Blind Spots

Meta Pixel, Conversions API, GTM, custom events — I wire up every touchpoint so you know which ad, which audience, and which creative drove each sale. Clean data means confident decisions. Confident decisions mean more revenue.

Your Brand, Everywhere It Matters

Facebook, Instagram, YouTube — all set up, branded, and connected. Content calendars, posting strategy, and growth systems so your audience builds while you sleep. I don't just create profiles. I create presence.

From "What If" to "It's Live" in 4 Steps


Every great product starts as a conversation. Here's how I take that conversation and turn it into something you can hold, share, and profit from.

01

Share Your Vision

You tell me the idea — I listen, ask the right questions, and map out exactly how we bring it to life. You leave with a clear roadmap — whether you hire me or not.

02

See It Before It Exists

I design high-fidelity prototypes you can tap through and feel before a single line of code is written. We refine until you look at it and say "that's exactly what I imagined."

03

Watch It Come Alive

Daily progress updates — you see your product being born in real time. No black boxes, no "big reveal" anxiety. You're part of the creation every step of the way.

04

Launch & Scale

Your product goes live. But I don't disappear — 30 days of support, performance tracking, and growth optimization. I stay until your creation is thriving.

Everything You Need to Know


I follow an agile methodology: Discovery, Wireframing, UI Design, Development (sprints), Testing (TestFlight/Internal), and Deployment. For Flutter projects, I use BLoC pattern for state management and implement CI/CD pipelines for automated testing and deployment to both the App Store and Google Play.

While Flutter provides pixel-perfect consistency, I respect platform conventions. I implement Platform Channels for native features, use adaptive widgets for iOS/Android differences, and conduct platform-specific UX testing. For desktop apps, I optimize for keyboard and mouse interactions.

Yes — and this is actually where I do my best work. Most websites fail because they were designed to "look nice" instead of to convert. I'll audit your current site, identify exactly why visitors aren't buying, and either optimize what you have or rebuild it with conversion-first design. The Growth System package ($1,395) is built specifically for this situation.

Absolutely. I handle the full setup — Meta Pixel installation, Conversions API, custom event tracking, and campaign architecture from scratch. I build campaigns with proper audience segmentation, lookalike audiences, and retargeting sequences. This is included in the Growth System package, or available as an add-on to any other package.

Every package includes revision rounds — we don't stop until you're genuinely happy. I show you progress daily so there are no surprises. In 4+ years and dozens of projects, I've never had a client ask for a refund. But if something isn't right, I fix it. Simple as that.

All packages include 30 days of bug fixes and support via WhatsApp. For ongoing work, I offer monthly retainers ($295/month) covering updates, content changes, performance monitoring, and strategy calls. For apps, I handle store updates and OS compatibility fixes so your app never breaks.

Yes — that's the entire power of Flutter. I write one codebase that compiles natively to iOS, Android, Web, and even Desktop. You get the same buttery-smooth experience on every platform, without paying for separate development teams. One build, every screen alive.

100%. Every line of code, every asset, every design file — it's all yours. I deliver the full source code via GitHub, and you have complete ownership. No vendor lock-in. No recurring license fees. Your product, your property.

Absolutely. I specialize in app redesigns and performance overhauls. I'll audit your existing codebase, identify bottlenecks and architectural issues, then rebuild from the inside out — cleaner architecture, faster rendering, modern UI. Many clients come to me after being disappointed by other developers. I fix what they couldn't.
