Senior Android & Kotlin Multiplatform Engineer
Building systems where AI intent meets deterministic mobile architecture.

What I Build

I work at the intersection of reliable mobile infrastructure and AI-powered decision logic - systems that take unstructured user intent and turn it into consistent, real-world outcomes.

Core areas:

• Kotlin Multiplatform architecture (Android + iOS shared logic)
• Offline-first data systems with resilient sync
• LLM integration with deterministic ranking layers
• Full-stack Kotlin - Ktor backends, PostgreSQL, deployed and live
• Android build performance and developer tooling
• Fintech infrastructure: transactions, cards, exchange, sync

Featured Work

SwiggyMind - AI Food Ordering Copilot

Describe your craving in plain language. Get ranked, actionable recommendations. Built on Swiggy Builders Club using KMP + Compose + OpenRouter.

• Natural language → structured intent parsing via LLM
• Deterministic ranking layer for consistent, non-random outputs
• Mind Cache for stateful session memory across conversation turns
• Designed for decision-making, not browsing

→ Shows how LLMs can power real consumer workflows when paired with structured reasoning.

droidperf - Android Gradle Auditor

npx droidperf audit - detects and auto-fixes Android Gradle performance bottlenecks.

• Supports Android, KMP, and Flutter project shapes
• Writes only to gradle.properties; creates timestamped backups before any mutation
• CI-ready with --json output and --dry-run diff preview

VellumLedger - Offline-First Finance + Live Backend

KMP expense tracker with a real deployed sync backend.

• Offline-first: every write lands in SQLDelight first, network is never a dependency
• SyncQueue pattern: PENDING → SYNCING → SYNCED | FAILED lifecycle per transaction
• Live Ktor + PostgreSQL backend on Railway with JWT auth and timestamp conflict resolution
• Biometric lock + SQLCipher database encryption

→ Complete end-to-end system in Kotlin. Backend: vellum-ledger-api

KMP Fintech Starter - Production KMP Template

Offline-first fintech architecture for Android + iOS from a single shared codebase.

• Shared domain, repository, and presentation logic via KMP
• SQLDelight as local source of truth; Ktor for remote sync
• Koin DI, Clean Architecture, CI pipeline included

→ Production-grade starting point, not a demo - built to be forked and extended.

Engineering Approach

I design for correctness first, then ergonomics.

That means:

• Deterministic systems over probabilistic ones where predictability matters
• Local-first architecture so the app works regardless of network state
• Failure paths treated as first-class concerns, not edge cases
• Clear module boundaries so logic stays testable without platform dependencies
