About Me
Hi, I'm Devendra Kumar
Mobile App Specialist
I help founders, businesses, and developers build, publish, fix, monetize, and grow Android & iOS apps.
Over the past 5+ years, I’ve helped launch 170+ apps across 12+ countries, working with startups, businesses, and developers in the UAE, USA, UK, Italy, China, India, and beyond. My expertise covers Flutter development, app publishing, store listing creation, ASO, AdMob monetization, and policy compliance.
Before going independent, I worked at Google (YouTube), where I learned that great products succeed when execution, processes, and user experience work together. That mindset shapes how I work today: clear communication, policy-first execution, and apps built for long-term success.

FAQ's
Answers to the most common questions from founders, businesses, and developers.
If you don’t see your question here, just ask — reply on the contact form below.
How long does app publishing actually take?
Most publishing and compliance projects are completed in 1–3 business days. Google Play’s own review process typically takes 3–7 days on top of that. Full Flutter development projects are scoped individually and timelines are agreed before we start.
What happens if my app gets rejected after you fix it?
This is rare, but if it happens, I review the new rejection reason and fix it at no extra charge as part of the original service. My goal is always a clean approval — and I stand behind the work until your app is live.
I'm not technical at all. Can you still help me?
Yes — most of my clients are non-technical founders. I handle the entire technical side: development, publishing, compliance, and store setup. You don’t need to understand Flutter, Google Play Console, or app policies. I’ll explain anything in plain language along the way.
Do you only work with Android, or iOS too?
Both. I develop and publish apps for Android (Google Play) and iOS (App Store), including Flutter apps that work across both platforms from a single codebase.
I already have a developer / agency. Can you just fix a specific issue?
Yes. Many clients come to me specifically for a rejection fix, a suspended account, or an ASO/monetization audit — without needing a full rebuild. Tell me what’s going on and I’ll scope just that piece.
Do you sign NDAs or keep my app idea confidential?
Yes, I’m happy to sign an NDA before any detailed discussion if you’d like one. Your idea, code, and business details are always kept confidential regardless.
What does the Monthly Retainer actually include day-to-day?
I monitor your app’s reviews, watch for any Google Play or App Store policy changes that could affect you, handle update submissions, and run monthly ASO checks — so your app stays live, compliant, and visible without you having to think about it. You can cancel anytime.
How do payments work for international clients?
I accept payments via Razorpay (cards, international transfers) and can also arrange PayPal or Wise for clients outside India if that’s easier on your end. Just mention your preference when we connect.
Can you help create store assets such as screenshots, icons, and descriptions?
Yes. I can assist with store listing creation, including app icons, screenshots, feature graphics, descriptions, metadata, and optimization to improve your app’s presentation and approval readiness.
