About
Full Stack Engineer with experience designing scalable systems at Singit (600K+ users), driving ~10% conversion growth and ~65% reduction in auth overhead.
I specialize in authentication, segmentation, and monetization infrastructure - building maintainable systems end-to-end, from backend APIs to polished frontend experiences. I leverage AI-assisted workflows (Cursor, Claude Code) to accelerate design and implementation.
Experience
Owned end-to-end architecture across authentication, segmentation, deep linking, and monetization systems for a language learning platform with 600K+ users.
-
Consolidated a fragmented user management system into a unified CRUD API - single source of truth eliminating inconsistent business logic and production edge cases.
-
Designed a Profiles & Segmentation architecture (freemium / trial / paying / B2B) formalizing user state transitions, feature gating, and access control across the platform.
-
Reduced authentication-related API calls during app initialization by ~65% by re-architecting the JWT authentication lifecycle, improving startup performance and lowering server load.
-
Drove ~10% increase in freemium-to-paid conversion rate by redesigning the payment flow - migrating from a static implementation to dynamic RevenueCat Paywalls with remote configuration and experimentation support.
-
Built a remote-triggered, localized UI system (modals, headers, custom HTML) configurable by country, device, and user profile - achieved ~10% phone-number capture rate among targeted users.
-
Engineered race-condition-safe deep link infrastructure integrated with remote UI configuration, enabling product teams to launch new experiences without app releases or backend deployments.

Things I've Built
Systems and apps I've designed and shipped end-to-end.

Movie Explorer
A modern movie discovery app with full keyboard navigation, Redux-Saga state management, and TMDB API integration. Features debounced search, favorites with localStorage persistence, dark/light mode, animated rating rings, and responsive design.

Pilewatch Operator Dashboard
A monitoring dashboard for grain storage operators to track sites, piles, live-style sensor readings, and open alerts in one place. Features sortable alert tables, pile status filtering, sensor detail views, and a light/dark/system theme with browser persistence.

Sympoll
Designed and deployed containerized microservices on Kubernetes with automated CI/CD pipelines, focusing on scalability and service isolation. Built to address the challenge of conducting effective surveys in environments where group conversations disrupt the process.
