Agniva and his team were great to deal with as they navigated through managing the scope of project and being dynamic with any alterations/changes and providing timely updates. It was a successful venture in which they produced and delivered the desired outcome of a mobile app and I would recommend their services to those keen on mobile app projects.

Job Success
Kharagpur, IndiaĀ - 9:21 am local time
Over the last 10 years, I've shipped 150+ products across mobile (Flutter, native iOS & Android), web (Next.js, React), and backend (Node.js, Firebase, AWS). My clients include early-stage startups launching their first MVP and established businesses scaling to hundreds of thousands of users.
Where I add the most value:
ā MVP development & rapid product launches: I help founders go from idea to a fully functional, market-ready MVP in weeks ā not months. Lean architecture, fast iterations, and real user feedback from day one.
ā AI-powered mobile applications: intelligent automation, recommendation engines, conversational AI, and GPT/Gemini integrations built natively into your product
ā Full-stack SaaS platforms: end-to-end architecture from database design and API development to admin dashboards, payment systems, and deployment
ā Complex multi-sided platforms: marketplaces, on-demand delivery systems, and subscription-based apps with real-time features, notifications, and role-based access
I've also been a founder myself (running a development firm since 2021), so I understand product timelines, budget trade-offs, and what it takes to ship something that actually works in the real world ā not just a demo.
My process is milestone-driven: we define scope together, I share progress builds at every stage, and nothing ships without thorough testing. You'll always know where things stand.
If you're building an MVP, scaling an existing product, or need an AI-powered app that works at scale ā send me a message with your project details, and I'll share an honest assessment and a clear roadmap.
