CODE
WITH
INTENT.
I create beautiful, high-performance, user-centric applications that run across platforms from a single codebase.
My foundation in C and C++ helps me understand systems under the hood and write optimized code.
Experience with Python and backend technologies lets me work across the stack, while Flutter remains the center of my cross-platform development work.

FAQ08 / 09
COMMON
QUESTIONS.
Most Flutter apps take 4–10 weeks depending on scope, from initial architecture to a store-ready build. I share a clear milestone breakdown before any code is written.
Yes. I regularly take over existing Flutter projects — auditing the architecture, fixing structural issues and continuing feature development without a full rewrite.
Regular async updates plus a short weekly check-in call. You'll always know what's shipped, what's in progress and what's next.
Yes — bug fixes, store updates and small iterations are available after launch, either as a retainer or on an as-needed basis.
Fixed-price for well-defined scopes, or hourly/retainer for ongoing work. You'll get a clear quote after a short discovery call — no surprise invoices.
