Cover image for ScopeBridge: Revolutionizing Freelance Project Clarity with AI

Excited to submit ScopeBridge for the Config Makeathon. Live Prototype: https://orchid-array-71734735.figma.site/ Figma Community File: https://www.figma.com/community/file/1649353646419325324 Why this idea Every freelance project starts with a conversation. Before pricing is discussed, clients and freelancers usually define requirements, priorities, expectations, assumptions, budget, and timelines through chat. But in many cases, quotes are shared before both sides fully understand what the work actually includes. This can create confusion for clients, uncertainty for freelancers, and project scopes that shift after the work has already started. ScopeBridge explores the step before proposal writing: scope alignment. Instead of helping freelancers simply generate faster proposals, ScopeBridge focuses on helping both sides understand the project better before the proposal or quote exists. The Solution ScopeBridge is a chat-side AI scope alignment assistant for freelance platforms. It sits beside a project conversation and turns early chat messages into quote-ready clarity by identifying: - What is already defined - What still needs alignment - Key assumptions - Important clarification questions - Suggested milestones - A structured scope packet both sides can review In the prototype, a client shares an early dashboard project idea. ScopeBridge analyzes the conversation, suggests alignment questions, updates the readiness score as more details are provided, and generates a structured scope packet before pricing begins. How I designed this I designed ScopeBridge using Figma Make as an interactive concept prototype. The workflow included: Framing the problem around freelance project communication Designing a simulated freelance chat interface Creating a ScopeBridge assistant panel inside the conversation Mapping the flow from early chat to alignment questions to quote-ready scope Adding a demo mode to show how scope clarity improves as the client provides more details Publishing both the live prototype and Figma Community file Impact ScopeBridge helps freelancers scope faster, clients communicate more clearly, and projects start with shared understanding instead of uncertainty. The goal is not to replace human judgment or negotiation. The goal is to create a clearer bridge between the first project conversation and the final quote.

Cover image for 🚨 Opportunity platforms lose 70%

🚨 Opportunity platforms lose 70% of users in the first 10 seconds — because the site makes finding opportunities feel like work. If your discovery platform isn't fast, clear, and trust-building instantly, visitors leave — and never come back. The Transformation — Somopportunity Before: Cluttered layout. No clear user journey. Hard to navigate on mobile. Zero SEO foundation. After: A clean, intuitive platform where jobs, scholarships, and grants are discoverable in seconds — on any device. What we fixed: ✅ Streamlined information architecture — users find what they need fast ✅ Mobile-first build — where 80%+ of job seekers browse ✅ SEO-optimized structure for opportunity-based search queries ✅ Trust signals and clear CTAs that drive sign-ups ✅ Lightweight, fast-loading pages to reduce bounce rate A platform that opens doors shouldn't have a broken front door. 👉 See it live: somoppurtunity.vercel.app (http://somoppurtunity.vercel.app)📩 Ready to redesign your platform?

Cover image for Case study: I rebuilt an

Case study: I rebuilt an activewear brand's entire storefront in 8 weeks — here's what happened to their revenue. The client had a big problem. $4M/year in sales, but 71% of shoppers were abandoning their cart. Their Shopify theme loaded in 4.6 seconds. Every flash sale crashed the server. Here's what I built and what changed: → Migrated from a legacy Liquid theme to a fully headless Next.js storefront → Implemented ISR so product pages load in under 400ms — even during traffic spikes → Built an optimistic slide-out cart that skips the 1.5s Shopify API delay entirely → Set up a Facebook CAPI proxy to recover conversion tracking lost to ad blockers → Gave the marketing team a Sanity CMS visual builder so they never need a dev again Results after 60 days: Page load: 4.6s → 0.8s (82% faster) Conversion rate: +34.6% Cart abandonment: down 18.3% Revenue directly attributed: +$142,000 Stack: React 19, Next.js App Router, Sanity.io (http://Sanity.io), Shopify GraphQL, Vercel Edge, Upstash Redis, Facebook CAPI, Cloudflare If your store is bleeding revenue due to slow load times or a rigid theme — let's talk.
