I build
production
products.
Mobile is my specialty. I've spent 8+ years shipping Flutter applications across fintech, payments, crypto and healthcare — apps that handle real money and real patients.
When a product needs more than an app, I build the rest: web interfaces, APIs, databases, authentication, payments and third-party integrations, all the way to the store listing.

05Mobile engineering
From pixels
to production.
I don't just implement screens. I take a mobile product from design through architecture, state, APIs, security and release tooling until it's in someone's hands.

07About
I'm Ugochukwu Dike.
I'm a mobile-first engineer and product builder. For 8+ years I've built Flutter applications for fintech, payments, crypto and healthcare teams — and taken most of them through the App Store and Play Store myself.
I think about the product, not just the screen: how the flow should feel, how the architecture will hold up, how the API, database, auth and payment layers fit together. When a project needs web work, I build that too. Modern tooling — including AI-assisted workflows — helps me move faster, but the job is the same as it's always been: ship something real that works.
Security is part
of the product.
- End-to-end encryption/decryption
- Secure financial data handling
- KYC integrations
- Secure API integrations
- Phone verification
- Fraud-resistant payment channels
08How I build
01
Architecture
Build maintainable application architecture before feature complexity becomes technical debt.
02
Product thinking
Understand the product and user workflow, not just the Figma file.
03
Security
Treat financial, identity and personal data as first-class engineering concerns.
04
Performance
Build interfaces and application flows that remain responsive as complexity grows.
05
Reliability
Build predictable state, API integrations, error handling and production workflows.
06
Delivery
Use CI/CD and deployment tooling to ship reliably and reduce release friction.
