    Hi there, I’d love to help you with your app. I've been an app developer for many years and have built numerous apps that have been featured in the Apple App Store and Google Play Store. I offer end-to-end service for Native and Cross-platform mobile applications development, Full-Stack development, and Custom Web development. My 360-degree process covers everything so you’re not left wondering, “What’s next?” I truly want to create an engaging user experience, deliver a solid return on investment, and help your business grow. MY ACHIEVEMENTS My passion for building apps that perform as beautifully as they look shows! Here’s a peek at some of my accomplishments: 1. Nespresso — Developed app that takes users on a “taste journey” filled with coffee flavors and aromas, all with a goal of enticing people to buy. 2. Celebrity Cruises — Developed cruise booking app that delivers a user-friendly experience that taps into their travel dreams. 3. Mercy Hospital — Developed the hospital’s web apps, empowering patients to manage their healthcare. These examples illustrate how I approach app development — with a thorough understanding of the company, its brands, and its users. WHY ME I’ve handled everything from simple mobile apps to complex web apps. I have a wealth of knowledge and additional resources available to me, which means I can deliver a complete 360-degree process. Where other developers may deliver a satisfactory finished product, I’ll ensure that not only will you receive an incredible app, but also complete app, marketing, and branding strategy. A few of the many skills I can provide: - Strategy planning - Brand design - UX / UI design - App development - Marketing & growth - Conversion optimization - Technical writeup - Wireframe sketching - Target user analysis HOW WILL I DO THIS I start by getting to know you, your products and services, your vision, and, most importantly, your users. From there, I develop a comprehensive strategy to attract, nurture, engage and convert users. For your project, I will do the following initial steps: - Sign a non-disclosure agreement. You can share your ideas with me with 100% confidence. I will protect your ideas as if they were my own. All of your information is held in the strictest of confidence and will not be shared with outsiders. It’s important to you, and it’s important to me. - Gather your requirements. - Create technical documentation communicating the app’s function and reason for being. The technical writeup describes your idea in detail, outlining its purpose, technical requirements, business logic, budget, timelines, technologies to be used, compliance issues, compatibility requirements, benchmarks and tests, challenges to be overcome, and other concerns. - Create wireframe sketches. This is the fun part where your app is sketched out! You’ll see exactly how the app will look and function. - Conduct in-depth market research. I want to know who are the most likely users for your app. What makes them tick? What challenges do they face? How can they benefit from your solution? The initial work should give us both a solid idea as to how the app will look and function on paper. Looking forward to working with you !
