About

10+ years shipping enterprise-grade web applications and frontend platforms using React, TypeScript, JavaScript, Angular, Redux, and modern delivery practices. I specialize in frontend architecture, reusable component systems, WCAG-minded accessibility, Core Web Vitals and Lighthouse-driven performance, enterprise UI platforms, SharePoint SPFx, and AI-assisted software development.

I have repeatedly delivered at scale for global organizations—McKinsey & Company (current), Verizon, MakeMyTrip, Marriott, and AT&T—across ecommerce, telecom, travel marketplaces, hospitality, and collaboration domains. I am comfortable owning architecture discussions, raising the quality bar through reviews, and mentoring engineers while partnering with product, UX, and backend teams.

I actively use GitHub Copilot, Cursor, and ChatGPT for AI-assisted debugging, automation, boilerplate acceleration, and productivity-focused workflows—without compromising code review, security awareness, or ownership. I also write on Medium (React, React Native maps, Firebase auth, UI animation) to share practical implementation notes with the community.

Selected impact

Problem → outcome snapshots tied to named programs—how I think about ownership, risk, and delivery in large product orgs.

Nagarro · McKinsey & Company

Fortune 500 UI platform at scale

Problem. Enterprise programs needed consistent, accessible UI across many teams and releases—without slowing product velocity.

Outcome. Led React/TypeScript architecture and reusable systems so squads shipped faster with fewer regressions; WCAG-minded patterns and performance budgets baked into the delivery rhythm.

  • React · TypeScript
  • Design systems
  • WCAG / a11y
  • Core Web Vitals

Nagarro · Verizon

Micro-frontends & migration under real constraints

Problem. Large legacy surface and mixed stacks made coordinated releases risky; teams needed a path to modern React without a big-bang rewrite.

Outcome. Defined atomic, micro-frontend-friendly structure and led Vue → React migration work so teams could evolve safely while still shipping to production.

  • Micro-frontends
  • Vue → React
  • Release risk
  • Team enablement

Mindtree · Marriott International

SharePoint & Microsoft 365 at enterprise depth

Problem. Stakeholders needed reliable intranet and collaboration experiences on SharePoint Online with governance and long-term maintainability.

Outcome. Delivered SPFx solutions, REST integrations, and Power Platform–aware workflows; supported production with clear ownership and iteration.

  • SPFx
  • SharePoint Online
  • REST APIs
  • Production support

Tools I use daily

AI-assisted engineering is part of how I ship—always with review, security awareness, and clear ownership.

  • GitHub Copilot

    Inline suggestions for tests, refactors, and boilerplate—speeds delivery when paired with strict review and ownership.

  • Cursor

    Repo-wide reasoning and edits for migrations and debugging; I treat it as an accelerator, not a substitute for architecture judgment.

  • ChatGPT

    Drafting edge-case checklists, API exploration, and doc synthesis—then I verify in code and against production constraints.

Production website

Aashvi Automotive

Production marketing site for a multibrand two-wheeler workshop—real customers, real constraints.

End-to-end site I designed and shipped for my own workshop: clear service positioning, fast mobile browsing, and trust signals for local search. This is the kind of work I enjoy—tight scope, honest UX, and iterative improvements grounded in how the business actually runs.

  • Complete services + credibility narrative with straightforward contact paths tuned for mobile-first discovery.
  • Typography, spacing, and navigation tuned for quick decisions on small screens.
  • Ongoing iteration based on real customer questions and shop operations—not a throwaway template.

Recommendations

Verbatim written recommendations from my public LinkedIn, followed by five recurring colleague-facing themes from the same public profile (skills, experience, and about).

LinkedIn
Ankur is by far one of the best JavaScript developers I’ve had the pleasure of working with. He has a unique approach of starting from the fundamentals and diligently working his way to the root of any problem when debugging. This methodical approach ensures that no issue goes unresolved. Beyond his technical skills, Ankur creates an exceptionally amicable and collaborative team environment. He is approachable, always willing to lend a hand, and makes sure everyone feels supported. Additionally, his passion for exploring new ideas and finding innovative ways to enhance functionality is evident in his work and in the projects he undertakes. I would give my highest recommendation to Ankur.
Vaibhav Gera
Colleague recommendation (LinkedIn)
I have had the privilege of working under Ankur and have been consistently impressed by his technical expertise, leadership skills, and dedication towards delivering top-notch quality coding solutions. He is very supportive and collaborative that brings out the best in the team. I highly recommend Ankur for any leadership position in the software development industry.

Colleague-facing themes (public LinkedIn)

  • Team leadership & mentoringLeading frontend engineers, code reviews, and knowledge-sharing — consistent themes across my public experience and skills on LinkedIn.
  • React & modern JavaScriptDeep work in React, Redux, and the broader JS ecosystem for customer-facing products; reflected in roles from Nagarro through earlier teams.
  • Micro-frontend & modular UIVue-to-React migration and atomic, micro-frontend-friendly component structure called out explicitly in my current role description.
  • Sprint delivery & client demosScrum participation, requirement clarification with clients, and sprint demos are recurring responsibilities in my public profile narrative.
  • Production support & qualityProduction support, A/B testing, and continuous improvement appear alongside performance and security-minded delivery in my LinkedIn story.

Performance on this site

This portfolio is intentionally lightweight: static-friendly App Router pages, `next/font` subsetting, and motion gated by `prefers-reduced-motion` where it matters.

I validate with Lighthouse and the Performance panel in Chrome DevTools on production builds—not a one-off marketing screenshot. Targets: stable LCP, low CLS, and no unnecessary main-thread work for first paint.

  • Static generation for primary routes; client islands only where interaction needs them.
  • Semantic landmarks, skip link, and keyboard-first patterns (⌘K palette) without blocking initial render.
  • JSON-LD, sitemap, and robots for discovery—same hygiene I apply to customer-facing properties.

Live sample

This site as a product UI

The same UX and accessibility patterns shipping teams use—implemented here so the site is a live sample of how I build.

Press ⌘K or Ctrl+K for quick navigation and actions—the command palette pattern used in Linear, Vercel, and Slack. .

Last content pass on this page: May 2026

  • Reading progress

    A slim page-progress bar at the top reflects how far you’ve scrolled—common in long-form product and docs sites.

  • Command palette (⌘K / Ctrl+K)

    Keyboard-first navigation, fuzzy filtering, focus trap, and Escape to dismiss—mirrors internal tools in modern product orgs.

  • Accessibility & motion

    Skip link, focus-visible rings, inert on the splash dialog, live regions where needed, and prefers-reduced-motion respected for parallax, scroll reveals, and Framer Motion.

  • Scroll & layout craft

    Parallax atmosphere, spring-based section reveals, and a zig-zag experience timeline—intentional motion without blocking content.

  • Discovery & performance posture

    Semantic structure, JSON-LD Person schema, sitemap/robots, and static-friendly Next.js App Router delivery.
