Platforms in production

Commerce and lead-generation platforms I designed, built and still maintain. Each of the live sites below was taken through a second, ground-up rebuild — new architecture, not a reskin.

01

Lucira Jewelry

Headless commerce platform

LiveRebuilt v2

2025 — present

lucirajewelry.com

Sole engineer on the migration of a D2C lab-grown diamond brand from a themed Shopify storefront to a headless Next.js + Shopify Storefront API + MongoDB architecture, serving ~500K monthly sessions across an omnichannel retail network in India.

  • Rebuilt the storefront from the ground up as a headless app — owning architecture, delivery, release, instrumentation and production support.
  • Migrated the full Savings Scheme product off a standalone subdomain onto the primary domain via a staged cutover, collapsing two codebases and hosting environments into one at full feature parity.
  • Shipped Vault of Dreams, a 9+1 month instalment savings product, on Razorpay with Ornaverse ERP-backed enrollment, instalment tracking and receipt reconciliation.
  • Built a metaobject-driven programmatic SEO system generating live Gold/Silver/Platinum rate pages across N+ Indian cities over a single shared rate-update path, preserving legacy URLs to retain search equity.
  • Built MongoDB-backed admin dashboards so marketing and ops self-serve daily metal rates, offers, homepage and city content — removing engineering from routine content changes.
  • Cut LCP 55% (28.0s → 12.7s) through image optimization, code splitting and render-path work.
  • Shipped a pincode journey resolving a shopper’s nearest store and re-ranking ready-to-ship inventory by proximity, with leads routed from GCP into Zoho CRM.

Lucira Mobile

React Native app

In progress

2026 — in progress

Extending the Lucira commerce experience to mobile with Expo — reusing the headless Shopify data layer already powering the web storefront so catalogue, cart and account stay in sync across surfaces.

  • Expo + React Native client consuming the same Shopify Storefront API layer as the web platform.
  • Native navigation, component and gesture fundamentals with a full CRUD implementation.
  • Shared session and account model so the mobile and web experiences stay consistent.

PrimeStyle

US jewelry storefront

LiveRebuilt v2

2024 — present

primestyle.com

Leading the end-to-end redevelopment of a production Shopify storefront for a US diamond and engagement-ring brand trading since 2001 — theme architecture, custom development and performance, with international stakeholders.

  • Rebuilt the storefront architecture rather than patching the existing theme — restructuring templates, sections and the product data model.
  • Advanced product customization flows for custom engagement rings and bridal sets.
  • Recommendation and merchandising surfaces across natural and lab-grown diamond catalogues.
  • Analytics instrumentation and performance work across the funnel.

2024 — present

chamundaconstructions.in

Designed, built and deployed a high-performance Next.js site for a Mumbai civil contracting firm specialising in building finishing work — built for lead generation, SEO visibility and brand credibility with builders.

  • Rebuilt from the ground up on a second pass — new information architecture around services, projects and process.
  • Project portfolio and service pages structured for local SEO across Mumbai search terms.
  • Quote-request journey and lead capture as the primary conversion path.
  • Responsive frontend with optimized content delivery and scalable content workflows.

Where I've shipped

Owning production systems end to end — architecture and delivery through instrumentation, release and support.

Sep 2025 — Present

Software Engineer

Mumbai, India

  • Sole engineer on the headless replatform: Next.js + Shopify Storefront API + MongoDB, at ~500K monthly sessions.
  • Built and maintain 50+ GA4/GTM dataLayer events across search, PDP, cart, checkout, payments, accounts and scheme funnels; configured Google Ads conversion tracking and order-level UTM pass-through so revenue attributes to campaign.
  • Modeled and joined source tables in BigQuery and exposed the payload via a Python REST API driving WebEngage notification triggers; built page-level Looker Studio dashboards.
  • Rebuilt the Ornaverse ERP integration twice through breaking upstream changes to request schema, headers and attributes, and fixed a defect where customers lacking an ERP record failed silently at payment.
  • Shipped and measured CRO changes — PDP and checkout social proof, above-the-fold offer placement, a paginated review redesign, rage-click fixes on customize and promo controls.
  • Built a ring-size estimation tool measuring against a reference card or coin, accuracy-validated across device screens, plus faceted PLP filtering and a self-serve return journey.
