Client results: • $350M+ raised by clients • 2M+ users on apps I designed and developed • 10K+ five-star reviews across apps built • Top 1% in App Design & Development on Upwork A few years ago, I was sitting exactly where many of my clients are today: trying to turn an idea into an app. I was looking for freelancers, tried to build it myself and hired the wrong teams. It was a nightmare to say the least. After years of mistakes and learning to code, I finally launched SchooLinks, which grew into an Inc. 5000 company and raised over $90 million. Since then, I've helped more than 150 founders launch products across SaaS, marketplaces, AI tools, mobile apps, and internal platforms... some of which have made it to Forbes.

Businesses often need more than just a developer. They need someone who can understand the requirement properly, suggest the right approach, and build a product that works smoothly in real use. I help startups, founders, and growing businesses build web applications, mobile apps, SaaS products, MVPs, and custom business platforms with a strong focus on clarity, performance, and long term scalability. With 15+ years of experience in software development, I have worked on projects from idea stage to launch, and also on existing platforms that needed improvements, feature expansion, workflow refinement, or complete redevelopment. My work covers both frontend and backend, so clients do not need to manage multiple developers for one product. I focus on understanding the business goal first, then translating it into a practical and reliable solution. This helps reduce confusion during development and keeps the project aligned with the real requirement. **What I can help with:** ---------------------------- • Custom web application development • Mobile app development (Hybrid and Native) • SaaS product development • MVP development • Admin panels and dashboards • API development and third party integrations • Ecommerce and marketplace platforms • Maintenance and feature enhancement of existing products **Tech stack I work with includes:** React, Node.js, Laravel, Flutter, Python, WordPress, Shopify, Swift, Kotlin, and API based integrations. Clients usually appreciate working with me because I bring clear communication, structured execution, dependable support, and a practical approach to solving product challenges. Whether you need to build a product from scratch, improve an existing application, or develop a stable MVP with the right technical foundation, I can help move the project forward in a clear and efficient way. If you are looking for a developer who can combine technical execution with a strong understanding of business needs, I would be glad to discuss the scope and suggest the right approach.
