[ENG-SERVICES] // MOBILE PRODUCT DEVELOPMENT
Production mobile products without unnecessary handoffs.
I build and extend mobile products across Flutter, React Native, backend integration, authentication, APIs, notifications, subscriptions, payments, native platform work, and release preparation.
The engagement is shaped around the product outcome—not around handing each technical layer to a different specialist.
One senior engineering owner across the product flow, with platform-specific help only where the work genuinely needs it.
- Flutter & React Native
- Backend-connected products
- Authentication & APIs

- Kotlin / Swift integration
- Release support
Where I can help
Mobile work shaped around the product stage.
The scope can be a first release, a major feature, a migration, or the next stage of an existing product.
New mobile MVP
Turn a validated product and known core workflow into a serious first mobile release with a scope that can actually be shipped.
Existing product extension
Add substantial functionality to an application that already has users, data, a backend, or an internal product team.
Major feature ownership
Own a feature across interface, state, authentication, APIs, notifications, data, and native behavior instead of splitting it into disconnected tickets.
Mobile version of a web product
Design the mobile workflow around device use and platform conventions rather than shrinking the website into a smaller viewport.
Cross-platform implementation or migration
Use Flutter, React Native, or a migration path when discovery shows it is the simplest suitable direction for the product.
Native integration and release support
Handle Kotlin or Swift integration where cross-platform code stops, plus production builds, configuration, signing, and store-readiness work within scope.
Cross-stack capability
Responsibility follows the workflow across technical boundaries.
The useful unit of delivery is a working product flow. That often crosses mobile, backend, third-party services, and native platform behavior.
Product experience
Navigation, product flows, forms, state, local persistence, accessibility, and clear loading, empty, and failure states.
Backend and data
Authentication, PostgreSQL and Supabase, storage, APIs, realtime behavior, and server or edge functions where appropriate.
Product infrastructure
Notifications, subscriptions, payments, analytics integration, environment configuration, and release support.
Platform integration
Android and iOS configuration, permissions, deep links, native SDKs, and Kotlin or Swift integration when the product requires it.
Development process
Disciplined delivery without methodology theater.
The sequence stays practical: clarify the outcome, expose risk early, build verified increments, and treat release as part of implementation.
Understand the product
Clarify the user, outcome, important workflows, constraints, and what a useful release needs to accomplish.
Define the scope
Separate the essential release from follow-on work and make assumptions, dependencies, and risks visible.
Choose the simplest suitable architecture
Understand existing systems when present and avoid adding complexity the product does not need.
Build in verified increments
Deliver reviewable slices that connect the interface to real data and expose integration problems early.
Test real product flows
Cover authentication, network and failure states, permissions, lifecycle changes, and platform-specific behavior—not only the happy path.
Prepare and ship the release
Complete production configuration, builds, signing, release checks, and store workflow agreed in scope.
Iterate from evidence
Use product feedback, observed failures, and relevant usage signals to choose the next work.
Keep ownership close to the product outcome.
A mobile feature rarely ends at the screen. It may depend on session state, database rules, an external API, notification delivery, platform permissions, or a store configuration change.
I can work across those layers and coordinate with an existing team where responsibilities are already established. The goal is not to own everything; it is to prevent the outcome from disappearing between handoffs.
One technical thread from product flow to release
Clear boundaries between mobile, backend, native, and third-party work
Existing systems preserved when they remain suitable
Risks and dependencies surfaced before they become release surprises
Production engineering
A feature is more than the screen that demonstrates it.
Build the real workflow
Features need to work inside authentication, data, network, lifecycle, and release constraints.
Make failure states explicit
Networks fail, sessions expire, APIs return unexpected data, permissions are denied, and apps move between foreground and background.
Respect the existing architecture
Working systems should not be rebuilt merely because another pattern is newer or more fashionable.
Keep product boundaries clear
Mobile, backend, native, and third-party responsibilities should remain understandable to the people maintaining them.
Release is part of the feature
A feature that works only on a developer machine is not a finished product outcome.
Mobile products with real workflows behind the interface.
SettleTab and Tare are relevant because their mobile experiences connect user input to structured product behavior. Project records remain deliberately limited to facts safe to publish.
SettleTab
SettleTab is a live Android app for itemized shared bills. People can scan a receipt or enter items manually, correct the bill, assign individual and shared purchases, calculate what each person owes, and share a read-only result.
Mobile product ownership around receipt input, editable itemized data, user correction, and bill-splitting workflows.
Tare
Tare is a mobile habit reflection app that saves original check-ins, proposes structured fields for user review, and uses recorded history for progress views and insight paths.
React Native habit reflection with saved original entries, reviewable AI check-ins, and Supabase data rules.
Tools selected for the product, not the pitch.
Typical work spans Flutter or React Native, Supabase and PostgreSQL, APIs, authentication, storage, realtime behavior, notifications, subscriptions, payments, and Kotlin or Swift integration. The actual stack follows the existing system and delivery constraints.
Common questions
Mobile development FAQs
Do you work with existing apps?
Yes. I can extend, stabilize, migrate, or take ownership of a defined area in an existing mobile product after understanding its current architecture.
Should we use Flutter or React Native?
That depends on the existing stack, team, platform requirements, integrations, and release constraints. I work with both and recommend the simplest suitable fit after discovery.
Can you handle backend work too?
Often, yes. I work across authentication, PostgreSQL and Supabase, storage, APIs, realtime behavior, and server or edge functions where they support the mobile workflow.
Can you work with our existing engineering team?
Yes. I can own a mobile workstream or defined feature while using the team's existing repository, review, planning, QA, and release practices.
Do you handle Android or iOS native integration?
Yes, where required. That can include permissions, deep links, native SDK configuration, and Kotlin or Swift integration around a cross-platform product.
Can you help with app-store release?
Yes. Release support can include production builds, signing and configuration, readiness checks, and the Google Play or App Store workflow when included in scope.
Do you offer fixed pricing?
For well-understood features or milestones, yes. Products with uncertain requirements or inherited systems usually need discovery before a reliable fixed scope is possible.
Can you take over from another developer?
Yes. Repository handoffs and partially completed products are normal. I review what exists before recommending major changes.
Can you build only one feature rather than the whole app?
Yes. A defined feature or product workflow can be a good engagement when ownership, interfaces, and acceptance criteria are clear.
Need to move a mobile product toward release?
Send the product stage, the workflow you need to build, and what is currently blocking progress. You do not need a perfect technical specification to start.
