Product Design, Growth and Developer
Cover image for I designed this website for
I designed this website for Kodsinc, a digital product and AI studio. The goal was to feel cinematic and ambitious from the first second, while explaining clearly what the studio builds and how it works with clients. The hero opens on a full-screen video of a glowing wireframe city with the Kodsinc wordmark at its centre. Beneath it, a tilted band scrolls through the studio's capabilities: AI voice agents, chat bots, automation, data and analytics, SaaS platforms and custom CRMs. As visitors scroll, the header condenses into a compact "Start a project" pill that expands into a numbered navigation menu. An AI assistant called Aria greets visitors, asks their name and offers suggested questions, so the site demonstrates the studio's own product from the start. For services, I designed a 3D card carousel. Seven vertical cards fan out side by side, and the selected one expands to reveal an illustration and the tools behind that service. The work section, "Work built to move," presents five products (Northstar, Flow CRM, AriaFin, WhatsApp SDR and Aria Assistant) as large stacked cards with device mockups. The page then builds trust. An interactive world map shows offices across five countries, and "Remote by location. Onsite in how we deliver" explains how the team stays close to clients. Security and compliance badges appear before the FAQ. The contact form sits beside the FAQ as a fill-in-the-blank sentence with a dropdown for the type of help needed. The page closes with the line "From Code to Intelligence," which sums up the studio in four words.

Cover image for I designed this website for
I designed this website for an AI studio that builds voice agents, chat agents and automation for businesses. The challenge was to make AI feel friendly and tangible to owners who have never heard an AI agent handle a phone call. The hero headline, "Your front office, answered by…", completes itself with rotating phrases in cobalt blue. The layout is clean and airy, with a soft periwinkle glow, a bold geometric typeface and a floating pill-shaped navigation bar. The centrepiece is the "Meet the Agents" showcase. I gave each AI agent a character and personality: Tom for real estate, Aria for marketing and Anna for private clinics. Each has a 3D illustrated figure, its own colour scheme and a giant typographic backdrop naming its industry. Visitors can switch between agents or start a live voice conversation in the browser, with microphone and speaker controls. Services are laid out as a bento grid of six tiles. Each opens a "see it work" window that explains how the service works, what's included and how to get started, so the details are there without crowding the main page. Past projects appear as stacked case study cards that layer on top of each other as you scroll, each showing a real dashboard preview. A bold cobalt band makes the business case, "Every missed call is a competitor's booked job," and it's followed by results, a dark process section titled "Live in weeks, not quarters," and a focused FAQ.

Cover image for I designed and built this
I designed and built this website for an award-winning aesthetic clinic in Fitzrovia, London. The goal was to feel like stepping into the clinic itself: calm, premium and personal, while guiding visitors towards the right treatment. The hero is a cinematic video of the clinic interior that moves forward as you scroll, while the headline "Advanced Aesthetics. Personalised Around You." gently fades away. It creates the feeling of walking through the door. I paired an elegant serif with gold italic accents, against a palette of warm cream, champagne gold and deep espresso. Navigation is built around the patient rather than the service menu. The "Start With What Matters to You" section offers two paths: browse by concern, such as ageing skin, redness or stubborn fat, or by treatment, for patients who already know what they want. Both paths use swipeable cards with real portrait photography. Trust runs through every section. The founder is introduced in a magazine-style feature, qualifications appear as clear credentials, and awards sit alongside "As Featured In" logos from national press. A results gallery can be filtered by skin, tightening, body and contouring. The full-screen menu brings every treatment, the clinic photo, the address, opening hours and a booking button into one elegant overlay. The page closes with a "Not Sure Which Treatment Is Right for You?" call to action, so undecided visitors always have a next step.

Cover image for I designed AutomateLine to sell
I designed AutomateLine to sell AI automation to everyday service businesses such as dental clinics, HVAC companies, plumbers and cleaners. These owners are busy and sceptical of tech buzzwords, so the site had to feel calm, practical and trustworthy, not like another AI startup. The headline, "Your best employee, always on.", frames AI as a reliable team member rather than a complex technology. I set it in a bold, tightly spaced typeface with a hand-drawn lime highlight under "always on." The palette is warm off-white, deep forest green and one bright lime accent, which keeps the page clean and confident. Instead of describing the product, I let visitors try it. The hero card is a live AI receptionist. Six agents, each set up for a different industry, can be switched with arrows or dots, and each card shows a real scenario, from incoming call to resolved booking. Visitors can call the agent or type to it directly on the page. The rest of the page follows the same idea: show, don't tell. A scrolling lime band repeats the outcomes owners care about. An "Ask the operating system" assistant answers setup questions with suggested prompts. A device carousel shows the voice calls, chat widget, SMS text-back, CRM pipeline, calendar and workflows. For the six core systems, I designed an interactive rotary dial, so choosing a service feels tactile and memorable. The contact form is written as a sentence, "Hi, I'm ___ from ___…", so getting in touch feels like a conversation rather than paperwork.

Cover image for Designed & Custom-built something fresh
Designed & Custom-built something fresh for OneOqood - a B2B real estate enterprise. The founder wanted an attractive first look that immediately grabs the attention of brands and organizations looking to scale their physical locations. A multi-layered search bar with tight copy clearly conveys OneOqood’s message right from the entry point. The footer links are clean, paired with a prominent big CTA. Would love some comments! Like for the final site URL and more design screenshots.

Cover image for Multi-Tenant ESG Reporting Backend with NestJS and AWS
ESG reporting is a workflow problem as much as a data problem: teams need applicability rules, evidence, consolidation, review, and approvals before a report is ready. For OriginSustain, I built NestJS/TypeScript backend services, PostgreSQL and Redis/BullMQ processing, and AWS/Docker delivery with CI/CD. OpenAI API and RAG support part of the reporting flow. The screens here are from the product’s illustrative command center; the numbers are demo values, not client outcomes.

A good donation flow needs dependable systems behind the screens. For Gabriel SGO, I built the NestJS/PostgreSQL backend for donor and school workflows, with PayPal donation processing, Redis/BullMQ background jobs, Mailgun email, and AWS delivery. The public experience helps Ohio donors estimate a contribution, choose a school, and understand the tax-credit process. I documented the backend work and real site screens here: https://contra.com/p/Ls6L2o7Y-gabriel-sgo-or-donation-and-school-allocation-backend

A college football roster is more than a list of stats when the goal is a Madden-ready draft class. For GridIronGC, I built the Node.js/TypeScript backend, conversion pipeline, and API, with Python stages and OpenAI-assisted data normalization. The live SaaS supports manual conversion, bulk uploads, and draft-class organization. I shared the real product screens and backend context in the case study: https://contra.com/p/3qRLLQ6c-grid-iron-gc-or-ai-assisted-player-conversion-backend

Cover image for US property owners managing renovations
US property owners managing renovations juggle scopes, service orders, and contractors across calls and spreadsheets. Renovate360 puts that workflow in one place, on web and mobile. I designed and built the AWS serverless backend: Lambda for compute, DynamoDB for data, CloudFormation for infrastructure as code. No servers to manage, costs that scale with usage. The platform covers property registration, project scoping, service order management, and real-time tracking across owners, managers, and providers, with a web app and React Native mobile app for on-site teams.

Cover image for A client once told me:
A client once told me: "I know exactly how much I sold this month. I just don't know until next month." That sentence is why we built the Smart Inventory & Ledger System. When stock, sales and accounts live in separate places, every decision runs late. You reorder after the shelf is empty. You chase dues you didn't know were overdue. You find out an item was your best seller when it's already out of stock. What the system does instead: • Flags low stock early and drafts the purchase order with AI • Posts every purchase and sale to the ledger automatically, with no re-typing • Answers plain-English questions about your sales, customers and stock in seconds • Puts sales, purchases, dues and payables on one dashboard The outcome: owners spend less time reconciling and more time growing. Fewer missed orders, cleaner books, faster calls. Watch the 15-second demo below. It goes from a low-stock alert to a restocked item, an updated ledger and an AI sales summary. Running a trading, wholesale or textile business on spreadsheets? Let's talk. DM me or book a demo at treesols.com (http://treesols.com). #Inventory #ERP #AI #BusinessGrowth #Pakistan

Cover image for Alma Collective, a fitness booking
Alma Collective, a fitness booking platform for the Greek market, was stuck: half-built by a previous developer, unstable, and nowhere near launch-ready. I took over the codebase, stabilized it, completed the missing core flows, and carried it to public launch across web and mobile (React Native). What shipped: User app: discover and filter classes (yoga, Pilates, dance), book and pay per session, QR check-in on arrival Partner portal: venue listings, class scheduling, payouts, subscriptions Payments: Stripe with Apple Pay and Google Pay, pay-as-you-go and subscriptions

Cover image for BioSonic is an AI-driven platform
BioSonic is an AI-driven platform for analyzing bat acoustics used by research teams across Europe. I built the full web portal from scratch and transformed it into a high-performance, scalable system capable of handling multi-terabyte datasets. My role covered full-stack development, infrastructure optimization, and performance engineering. I optimized Supabase RPCs and SQL queries, achieving 5× faster data retrieval and 240% faster file loading, while stabilizing AWS services to eliminate downtime. I also enhanced the SQS-based job distribution system for parallel data processing and implemented EC2 monitoring tools for better reliability and proactive scaling. This project showcases my ability to own complex systems end-to-end, improve large-scale performance, and deliver production-ready solutions under tight deadlines, all while maintaining clear communication and client satisfaction. “Hammad created our web portal from nothing in 3 months, optimized it beyond expectations, and always went the extra mile.” — Josef Carlson
