Architecting Scalable Backends | Crafting High-Conversion Frontends | Optimizing Performance & SEO

I am a Full-Lifecycle Software Engineer dedicated to building digital products that scale. My approach combines the rigor of Enterprise Backend Architecture (NestJS, multi-tenancy, event-driven systems) with the precision of High-Performance Frontend Engineering (Next.js, SEO, and accessible UI).

I specialize in transforming sluggish, monolithic applications into lean, distributed systems. My recent work involved optimizing a SaaS platform's core vitals, reducing API latency by 99%, and ensuring a "Perfect 100" Lighthouse score for maximum search engine visibility.

• Frameworks: NestJS, Node.js, Express, Laravel (PHP).
• Data Strategy: PostgreSQL (Prisma), Redis-distributed caching, BullMQ for background processing.
• Patterns: Multi-tenant isolation, Event-Driven Architecture (EDA), Transactional Outbox.

• Core: React, Next.js (App Router), TypeScript.
• Design: TailwindCSS, Shadcn/UI, Mantine Core, Responsive Design.
• Growth: Core Web Vitals optimization, Semantic HTML, SSR/ISR strategies, metadata & schema.org implementation.

Lead Architect

• Full-Stack Ownership: Engineered an end-to-end multi-tenant system for 100+ schools.
• Backend Performance: Solved concurrency bottlenecks using Logical Versioning in Redis, reducing response times from 6.4s to 59ms.
• Frontend & SEO: Built a blazing-fast marketing engine and dashboard using Next.js, achieving top-tier SEO rankings through optimized Server-Side Rendering (SSR) and automated metadata generation.
• Stack: NestJS, Next.js, Prisma, PostgreSQL, Upstash Redis.

Software Engineer

• Headless Architecture: Developed a unified NestJS API serving distinct storefront and admin applications.
• UX & Scale: Implemented high-frequency read caching for product catalogs, ensuring sub-100ms LCP (Largest Contentful Paint) for optimal user retention and SEO performance.

Open Source Builder

• Engineered a Chrome extension to intercept and analyze HTTP traffic, demonstrating a deep understanding of browser internals and networking protocols.

I am passionate about solving complex engineering challenges that directly impact business growth. Whether it's architecting a database for a million records or fine-tuning a React component for 0.1s faster interaction, I build with Quality, Performance, and SEO in mind.
