About

PROFILE

I'm a backend engineer focused on system design, API architecture, and scalable infrastructure. Currently leading backend at GlamGuider (Admobs), a beauty-tech platform serving 30K+ users across web, Android, and iOS.

My strength isn't writing the most lines of code — it's thinking in systems. Deciding how a loyalty ledger should be structured for multi-country rules, how to split a heavy data pipeline from a fast-serving API, where the bottlenecks will appear before they do. I own API contracts, infrastructure, and cross-team execution.

I also run my own business — so cost-awareness and product thinking sit inside every technical call I make. I build for the outcome, not just the spec.

Selected Systems

06 ENTRIES
/01 Loyalty Wallet & Reward Engine GLAMGUIDER

A reward system built on a transaction ledger with country-specific rules, so every credit and debit is auditable and reward computation stays correct as the platform expands. Designed for consistency over convenience — the ledger is the source of truth, balances are derived.

/02 Product Comparison & Intelligence System IN PROGRESS

A queue-driven pipeline for ingredient-level product intelligence — comparing skincare products by safety, skin-type suitability, and multi-platform pricing. Architected to separate heavy offline ingestion from fast online serving. I authored the HLD and pitched the product roadmap behind it.

/03 Affiliate Tracking & Attribution GLAMGUIDER

An affiliate tracking and conversion attribution system with an event pipeline feeding behavioral analytics. Makes monetization measurable — which source drove which conversion — so product decisions run on data, not guesswork.

/04 Infrastructure Migration GLAMGUIDER

Led the migration from a single-server setup to a scalable stack — VPS hosting, MongoDB Atlas, and AWS S3 + CloudFront CDN. Improved reliability and cut media latency by serving assets from the edge instead of the origin.

/05 Admin-Driven Content System GLAMGUIDER

A backend-controlled content and drag-and-drop banner system that lets non-engineers update UI with zero code deployments — removing engineering from the loop for routine content changes and speeding up publishing.

/06 RemindFlow — SaaS INDEPENDENT

A reminder and scheduling SaaS product built end-to-end — system design, backend, integrations, and deployment. A 0-to-1 project owned solo, from architecture to a running product.
