About

Professional summary

I am a Front-End Engineer with over five years of experience building scalable web platforms, administrative systems, AI-powered interfaces, and high-load consumer products. My core expertise is in React, Next.js, Remix.js, TypeScript, and modern frontend architecture.

I currently work on an AI-driven real estate platform, where I proposed and led a complete rewrite of a legacy frontend. I own architecture decisions and delivery across a TypeScript/TSX codebase serving international UK and UAE markets.

I build robust data-driven user experiences using React Query, REST APIs, GraphQL, WebSockets, and Server-Sent Events. I have designed typed service layers, streaming AI interactions, map-based analytics products, document workflows, and complex multi-step application flows.

Previously, I contributed to a global ticketing platform serving more than two million monthly users. I also acted as Product Owner for an internal administration panel used by managers and support teams.

I am comfortable working end to end, from translating product needs into technical solutions to implementing interfaces, reviewing pull requests, writing tests, and maintaining production systems. I enjoy proposing practical architectural improvements, including migrations from unstable WebSocket flows to SSE-based streaming.

I also have experience mentoring trainee developers through code reviews and pair programming. I value maintainable code, clear collaboration, and delivering polished user-facing products that solve real business problems.

Front-End Developer HomeHapp AI

I proposed and led a full rewrite of the legacy frontend, delivering the replacement as the sole frontend developer. I own more than 39,000 lines of TypeScript and TSX, including architectural decisions and production delivery.

I built a dual-region UK/UAE architecture with host-based API, currency, and endpoint resolution, backed by typed services and React Query hooks. I also rebuilt the HAPPI AI assistant with Server-Sent Events, developed agent workspace analytics for more than 600,000 listings, and delivered a multi-step AI research report flow with document upload, streaming progress, reconnect logic, and PDF export.

Front-End Developer Entire Framework

I developed and enhanced a high-traffic event platform serving more than two million monthly users in the global music and events industry. My work included migrating APIs to a new ticketing system and delivering account features for users to view and manage purchased tickets.

I acted as Product Owner for an internal administration panel used by managers and support staff to manage events, payments, invoices, and tickets. I also completed inherited integrations, integrated the client design system, reviewed pull requests, contributed unit tests, and participated in client planning sessions.

Full-Stack Developer Wpwp

I built an internal operations platform from scratch for a web agency managing WordPress marketplace orders. The platform reached production in approximately seven months and was used daily by a team of 20 to 25 people.

I implemented ClickUp synchronization with a server-side request queue that respected API limits, resumed failed requests, and prioritized urgent work. I also designed a project-order-task data model and delivered dashboards, task boards, invoicing, payroll, payment, and cost-estimation workflows.

Front-End Developer Saphira Agency

I delivered four to five client web applications end to end using React and Next.js, from layout implementation through production release. My projects included real estate integrations with Instagram feeds and Google Maps.

I developed interactive 3D interface work using Three.js and replaced a frame-by-frame PNG animation with a rotating sapphire model. I also built a restaurant ordering flow with map-based delivery zones, Redux cart management, delivery and pickup checkout, and working-hours-based time slot selection, while mentoring a trainee developer through reviews and pair programming.
