About Ankit Mittal

PageSpeed 50 → 90. Bundle size 1.5MB → 350KB. Integration time 10 days → 2 days. I don\'t just write frontend code — I engineer systems where performance is a product feature.In 5 years at Primathon, I\'ve shipped 8+ production systems across fintech, e-commerce, and real-time data platforms — progressing from SDE 1 to SDE 3. Today I lead frontend architecture for a large-scale e-commerce marketplace with AI integration, making core decisions on rendering strategies, event systems, and platform-level performance budgets.What I\'ve shipped (with numbers):→ Architected an event-driven communication system — cut client integration time from 10–12 days to 2–3 days→ Built real-time financial data interfaces with SSE — increased user engagement by 10–15%→ Led a full web performance overhaul — PageSpeed from 50 to 90, load time from 2.5s to under 1s→ Reduced JS bundle sizes from 1.5MB to 350KB through code splitting, tree shaking, and dynamic imports→ Designed a JSON-based dynamic layout system — cut new page development time from days to hoursWhat I own now:Frontend architecture and performance engineering for a high-traffic e-commerce marketplace. I define Core Web Vitals budgets, design event architectures, establish engineering standards, and drive technical hiring. I make the system-level decisions that determine whether the platform is fast, reliable, and shippable.I also mentor engineers on advanced JavaScript internals and React patterns — internally and through 1:1 sessions on Topmate — and share technical breakdowns with followers.If you\'re building something where frontend performance is a competitive advantage, let\'s talk.

1. Sde 3 Senior Software Engineer

   Primathon

   Dec 2024 — Present · Gurugram, IN

   Own frontend architecture and performance engineering for a large-scale e-commerce marketplace platform with deep AI integration — serving high-traffic consumer experiences across web and mobile web, with performance budgets enforced across every critical user journey- Make core system design decisions — selecting rendering strategies (SSR, ISR, CSR), designing event architectures, defining state management patterns, and building data-fetching layers — balancing performance, reliability, and developer velocity across a multi-engineer frontend team- Defined and enforce the platform\'s Core Web Vitals strategy: set performance budgets, built observability pipelines for real-time regression detection, and drove Lighthouse score improvements across checkout, search, and product discovery flows- Established the frontend engineering playbook: code review standards, component architecture patterns, performance checklists, and CI/CD quality gates — creating a repeatable system for consistent, high-quality output as the team scales- Drive technical hiring and mentorship — designed the frontend interview loop, conducted system design rounds, onboarded new engineers, and led weekly deep-dives on advanced JavaScript internals, React performance patterns, and architectural thinking.
