Full Stack Engineer @Tuna Software Solutions
Verified
Full stack developer with 5+ years of experience designing and building the systems behind high-traffic platforms, data pipelines, and product experiences that scale. Currently at Tuna Software Solutions, I lead development of a Next.js content platform serving millions of monthly visitors for a major US entertainment brand (Six Flags). I architect backend services on AWS with Redis caching layers to maintain sub-200ms response times at scale, and drive front-end performance and Core Web Vitals optimisation to improve organic search rankings. Previously, I built a distributed Golang crawler at Growth.cx capable of processing thousands of domains concurrently, led a team of 5 front-end developers, and integrated payment systems (Stripe, Razorpay, PayPal) into production SaaS products at Sugoi Labs. My freelance work spans e-commerce platforms, donation systems, e-learning marketplaces, and travel booking applications. My work covers the entire stack — from crafting responsive, accessible interfaces to architecting distributed backends and deploying cloud-native infrastructure.
