Six service lines, all delivered end-to-end by one senior engineer.

### 1. Shopify stores

Custom Shopify themes built from Figma. Shopify Plus support. Custom Liquid sections. Product and landing pages. Checkout tweaks. Mobile-first responsive layouts with performance budgets enforced from the first commit. Configurable sections so the team can re-merchandise without touching code.

Stack: Shopify, Liquid, Shopify Plus, Custom Sections, Figma.

### 2. Shopify custom apps

Bespoke Shopify apps and API integrations for problems no public app solves. Subscriptions, loyalty, ERP sync, custom coupon APIs, headless storefronts on Hydrogen. Order-webhook plumbing that hands off cleanly to back-office tools.

Stack: Shopify Admin API, Hydrogen, Node, Webhooks, Multi-tenant SaaS.

### 3. Performance and conversion

Core Web Vitals tuning (LCP, CLS, INP, TTFB). Image and JS budgets. Mobile-first design passes. Checkout funnel instrumentation and A/B-tested fixes. The same traffic, more orders.

Stack: Lighthouse, PageSpeed, PostHog, Real-user metrics.

### 4. SaaS products and dashboards

Production SaaS products built end-to-end — auth, billing, multi-tenant data, dashboards, integrations. Next.js, React, TypeScript on top of Postgres with Prisma. Stripe for billing.

LLM-powered web apps, automation tools, and AI agents for internal teams and customer-facing surfaces. OpenAI APIs wired into Next.js apps with proper streaming. Retrieval-augmented generation (RAG) over real documents — Postgres + embeddings, with eval rubrics. Multi-step AI agents that call tools, branch, and self-check. Prompt versioning, eval suites, observability so the AI does not regress silently.

Stack: OpenAI, RAG, Agents, Evals, Streaming.

### 6. Webflow and WordPress

Marketing sites and content-driven websites. Custom WordPress themes (no page-builder bloat). Webflow builds with structured CMS collections. SEO baseline: meta, OG, structured data, XML sitemap, canonical handling. Editor-friendly content blocks so the team owns the content after launch.

## Process

Six steps, fixed-price or hourly.

1. **Collaborate** — 45-minute discovery call, written brief, audit notes. Tools: Notion, Loom, Slack.

3. **Approve** — signed SOW with milestones, fixed-price or hourly. Tools: DocuSign, Upwork, Stripe.

## Selected work (case studies)

### KonstantKreative — WordPress (2018, ongoing)

8+ years of custom WordPress development. Weekly landing pages on a custom Stripe checkout, GoHighLevel signup flow, and Zapier sync layer.

The funnel runs on custom Stripe SDK shortcodes rather than an off-the-shelf plugin. When someone signs up through a GoHighLevel form, the shortcode picks up the email automatically, pings a Slack channel, and writes the lead to a tracking sheet. When the payment clears, Slack gets a second alert and the sheet updates — so the team always sees signup-to-paid in real time. A Zapier flow on top of Stripe keeps the app and team channels in sync — every successful payment, every cancellation a few months in.

- 5+ years ongoing partnership
- Weekly landing pages shipped
- Custom Stripe checkout shortcodes
- Real-time signup-to-paid tracking

Stack: WordPress, Elementor, Custom Shortcodes, Stripe SDK, GoHighLevel, Zapier, Upstash Redis, PostHog, Facebook Pixel, Figma, Slack.

### DavidVon — Shopify (2023)

Custom Shopify storefront with personalized products, smart discounts, auto shipping protection, and a multi-vendor SaaS for jewelry workshops.

End-to-end Shopify build: every screen designed in Figma, developed as a custom mobile-responsive theme, every section configurable in the Shopify customizer. The product experience is built around customization: buyers add their name to a necklace through a custom property field, and that value rides on the line item all the way through checkout to the order — fulfillment sees exactly what to engrave. Auto-discounts surface on the product page itself (something Shopify does not do natively). Shipping protection is auto-added at checkout, scaled to product cost.

Beyond the storefront, a multi-vendor SaaS lets DavidVon's partner workshops log in to add products, see incoming orders, share jewelry design previews with the client for sign-off, and update production progress as the piece moves through the workshop.

- Custom Shopify theme
- Personalized name-on-jewelry product flow
- Auto product-page discounts
- Multi-vendor workshop SaaS

Stack: Shopify, Liquid, Custom Sections, Line Item Properties, Figma, JavaScript, HTML/CSS, Multi-vendor SaaS.

Live: https://davidvon.com/

### Recovapro — Shopify + Apple Fitness+ (2023)

Custom Shopify storefront with a coupon API that hands every customer an Apple Fitness+ 4-month trial code at checkout.

End-to-end Shopify build with a custom coupon service sitting next to it. Recovapro partnered with Apple Fitness+ as a purchase incentive. A Shopify order webhook fires on every purchase, the API reserves the next Apple Fitness+ code, binds it to the order, and surfaces it on the thank-you page — all server-side, all hands-off. The flow is invisible: complete a purchase, the code is waiting on the thank-you page.

- Custom Shopify theme
- Coupon API with Apple Fitness+ code pool
- Order webhook for auto code delivery
- Instant Apple perk on thank-you page

Stack: Shopify, Liquid, Custom Sections, Custom API, Order Webhooks, Node.js, Figma, Apple Fitness+ codes.

### PAININJURYLAW — Next.js SaaS (2023, ongoing)

Large SaaS app built end-to-end in Next.js for PAININJURYLAW. Postgres with Prisma underneath, and a deliberately unified workspace for legal teams — matters, contacts, communication, documents, eSign, and intake all in one place.

The app is organized around the matter. Every interaction — a call, an email, a meeting, a signed document, a new intake form submission — is attached to the matter. Twilio for voice and SMS, Nylas for email and calendar, AWS S3 for documents, Docuseal for eSign, plus a custom widget intake form the firm drops onto landing pages and third-party sites to capture new leads directly into the workspace.

- Next.js full-stack app
- Postgres + Prisma data model
- 5+ tools unified in one workspace
- 2+ years ongoing engagement

Stack: Next.js, React, TypeScript, Postgres, Prisma, Twilio, Nylas, AWS S3, Docuseal, Tailwind CSS, Widget SDK.

### PAININJURYLAW — WordPress marketing site (2022)

Designed and built the PAININJURYLAW marketing site end-to-end in WordPress. Every page — homepage, practice areas, attorney profiles, contact, blog — designed from scratch and implemented as a custom theme. Clean custom theme, no page-builder bloat. Editor-friendly: practice areas, attorney bios, and blog posts maintained by the team without a developer in the loop.

Stack: WordPress, PHP, Custom theme, Advanced Custom Fields, HTML/CSS, JavaScript, SEO.

Live: https://paininjurylaw.com/

### Dot Vitamin — Shopify (2024)

Full Figma → Shopify build. Custom theme, mobile-first, editor-friendly across every section. Calm clinical brand aesthetic. Every section in the design is a configurable block in the Shopify editor so the team can re-merchandise and run campaigns without touching code.

Stack: Shopify, Liquid, Figma, HTML/CSS, JavaScript, Performance optimization.

### LottoSocial — Gatsby (2022)

Gatsby engagement on the LottoSocial site. Took a Figma design pass and turned each screen into reusable, typed React components inside the existing Gatsby project. Diagnosed and fixed long-running Gatsby issues — build pipeline failures, hydration problems, plugin conflicts — at the root. Final pass was SEO: every page got proper meta tags, social cards, canonical handling, and the XML sitemap was rebuilt and resubmitted.

Stack: Gatsby.js, React, TypeScript, GraphQL, Figma, SEO tooling, XML sitemap.

## What Kashif Anjum does NOT do

This is the negative-space scope. Engagements outside this list are not accepted.

- Native iOS or Android apps (web only).
- White-label reselling arrangements.
- 24/7 on-call support retainers. Two weeks of post-launch support is included in every engagement; longer support is bookable as a separate retainer.
- Large legacy codebase maintenance as the primary scope (over 100,000 lines of unfamiliar code).
- Marketing-only websites below the cost of a custom Shopify build. Webflow and WordPress are referred to a content team in those cases.
- Single landing pages or one-off audits below the 4-week minimum engagement size, with rare exceptions for existing or referred clients.

## Industries Kashif Anjum has worked in

- Legal tech (PAININJURYLAW — Next.js SaaS for matter management)
- Ecommerce and personalized jewelry (DavidVon)
- Wellness and recovery (Recovapro, Dot Vitamin)
- Lottery and gambling (LottoSocial)

## Choosing between Shopify, Webflow, and WordPress

| If you are... | Choose |
|---|---|
| Selling products, need app integrations, subscriptions, or scale | **Shopify** |
| Building a content-heavy marketing site with minimal ecommerce, want a visual CMS | **Webflow** |
| Need extreme customization (custom Stripe checkouts, complex membership flows) | **WordPress** |

Recommendation is made on the discovery call based on what the project actually needs, not the platform Kashif is most paid to build.

## Glossary of terms used across this portfolio

- **Shopify Plus** — Shopify's enterprise-tier plan that unlocks custom checkout extensions, Shopify Functions, B2B catalogs, and dedicated launch engineer support. Used by stores doing $1M+ in annual revenue or those needing checkout customizations the standard plan does not allow.
- **Shopify Liquid** — Shopify's server-side templating language for themes. HTML mixed with placeholder tags (`{{ product.title }}`) and logic tags (`{% if ... %}`).
- **Shopify Hydrogen** — Shopify's official Remix-based framework for building headless storefronts in React. Pairs with Oxygen for hosting.
- **Headless commerce** — Architecture pattern where the storefront UI is a separate React/Next.js/Hydrogen app talking to a commerce backend over an API.
- **Core Web Vitals (CWV)** — Google's three user-experience metrics: LCP (Largest Contentful Paint), INP (Interaction to Next Paint), CLS (Cumulative Layout Shift). Targets: LCP < 2.5s, INP < 200ms, CLS < 0.1.
- **Retrieval-Augmented Generation (RAG)** — AI pattern where the system retrieves relevant document chunks from a search index or vector database, then passes them to an LLM as context for its answer.
- **AI agent** — LLM-powered system that calls tools, evaluates results, and decides next steps. Production agents need eval suites, retry handling, and observability.
- **AI evals** — Automated test suites for LLM outputs. Score on accuracy, format compliance, hallucination rate. Without evals, AI features regress silently when prompts or models change.
- **Multi-tenant SaaS** — Architecture where many customer organizations share one application instance with isolated data, typically via a `tenant_id` column on every table.
- **Top Rated Plus (Upwork)** — Upwork's highest freelancer tier, top 3% by sustained client outcomes (long-running contracts, large contract value, sustained 90%+ job-success score).

- **Conversion Rate Optimization (CRO)** — Practice of improving the percentage of visitors who complete a desired action (buy, sign up, book a call).
