Thoughtful architecture, secure foundations, and the details that make an app feel native.
A bit about me
Invested in
the product.
I'm Bolarin, a senior React Native developer with 4+ years across healthtech, fintech, and consumer apps.
For me, ownership starts with understanding the problem and helping the team decide what matters. It means making thoughtful trade-offs, taking responsibility for delivery, and staying involved after launch to see what needs to improve.
At PSL, I led three mobile engineers delivering fintech products that enabled over NGN 20 million in credit for 100+ SMEs. That is the kind of outcome I want my work to contribute to.
Download my CVWhat I bring to a team
01Product ownership
Understanding the user problem, helping shape scope, and connecting technical decisions to what the product needs. I stay accountable for the quality of the release and what happens after it reaches users.
02React Native architecture
Choosing a foundation that fits the product today and leaves room to grow: feature structure, typed navigation, reusable components, and reliable state and data flow.
03App security & privacy
Authentication, access control, and careful handling of sensitive data across the app and its APIs. My work in healthtech and fintech puts user privacy and security at the centre of everyday engineering decisions.
04Native-feeling product UX
Bottom sheets, gestures, loading states, empty states, forms, and transitions tuned so the app feels deliberate on real devices.
05Technical leadership
Leading delivery, reviewing code, mentoring engineers, and working through decisions together. I care about the team's ability to keep improving the product, not just my own contribution.
06Launch, learn, improve
QA, store approvals, and the work after launch. At NaraTherapy, I set up interaction tracking and managed live updates and ongoing improvements, keeping product quality in focus beyond the first release.

Backend engineering
Beyond the app.
I also build the services behind the screens: APIs, data, authentication, and the connections that keep a product running.
At NaraTherapy, that included Go APIs for journaling and mood tracking, Stripe subscriptions, and calendar scheduling.
Go & API design
RESTful services and concurrent workflows using goroutines and channels.
Authentication & data security
Authentication and authorization with JWT and Firebase Auth, with attention to access control and sensitive user data.
Realtime & integrations
Event-driven features, subscription payments, and calendar scheduling.
AI development & agentic coding
AI in the product.
Codex in the workflow.
I build AI features into products, including the chatbot experience in NaraTherapy. That work connects conversational interfaces with the mobile app and its backend services.
I also use Codex as a coding partner. It helps with exploration, implementation, and iteration; I own the product decisions, review, and quality of what ships.
How I work with coding agents
Codex + engineering judgmentFrame the problem
Start with the user need, the codebase, and the constraints. Give the agent clear context and define what a good result looks like.
Build with Codex
Work in focused changes. Use the agent to explore options and implement, then steer the work as the product and technical details become clearer.
Review and verify
Read the diff, check access control and sensitive-data handling, run tests, and try the experience. Agent-generated code gets the same scrutiny as code I write myself.
Ship and follow through
Own the release, respond to feedback, and keep refining. The work is done when it solves the problem, not when the agent finishes.
