I fix broken hosting setups and billing systems — WHMCS, Blesta, cPanel, CWP, CyberPanel and Webuzo — often the same day. Most clients reach me after something has already gone wrong: a payment gateway that stopped taking orders, a migration that half-finished, an SSL chain that only fails in some browsers, a control panel throwing 500s, or a server that got compromised. That is the work I do every day, and have since 2012. WHAT I GET CALLED FOR • WHMCS / Blesta / WISECP setup, upgrades, module and payment gateway failures • Control panel install, migration and repair — cPanel/WHM, CWP, CyberPanel, Plesk, Webuzo, DirectAdmin, aaPanel • Server-to-server migration with minimal downtime (cPanel to CWP, shared to VPS, host to host) • SSL certificate installs and intermediate/chain errors that break for some visitors but not others • Malware removal and hardening on hacked WordPress, WHMCS and OpenCart sites • Email deliverability — Postfix/Exim, SPF, DKIM, DMARC, rDNS, blacklist removal • LAMP/LEMP tuning, PHP-FPM, MariaDB, and "why is my site slow" diagnosis WHY CLIENTS KEEP ME I have administered this exact infrastructure daily since 2012 — across OVH, Hetzner, Contabo, DigitalOcean, Vultr, Linode, UpCloud, AWS and Google Cloud — so I am not learning your stack on your budget. I find the actual root cause before I touch anything, I take a rollback point first, and I tell you plainly what broke and why. FROM MY UPWORK CLIENTS "one of the best developer for webuzo related work" "Great job, and faster than you quoted." "Thank you for your quick help!" Send me the error message, the URL, or the panel you are stuck on, and I will tell you what is actually wrong — usually before you hire me. — Benjamin

I thrive on the challenge of building robust infrastructure that can handle the demands of millions of users while ensuring it remains secure and efficient. My journey began in Bangladesh, where I contributed to one of the country's leading newspapers—an experience that taught me how to develop applications that engage users under pressure. Since then, I’ve transitioned into the world of DevOps, where I’ve found my true calling. Whether you are migrating from shared hosting to the cloud or need to scale a Kubernetes cluster to handle massive traffic spikes, I provide the "push-button" infrastructure stability you need to focus on your product. I help businesses reduce cloud costs by designing efficient architectures, automating resource management, and continuously optimizing CLOUD environments for maximum performance and savings.

Marketplaces, directories, booking platforms, and listing sites are harder to design than ordinary websites — because they serve several audiences at once. Buyers want to search fast. Sellers want visibility and leads. Vendors want simple onboarding. Admins need control. And the business needs trust, conversion, and a workflow that stays clean as the platform scales. I design marketplace, directory, search, listing, booking, rental, local-business, service, property, and job-board experiences in Figma — for web and mobile. My focus is making complex search and comparison flows feel simple, intuitive, and conversion-focused. 𝐖𝐡𝐚𝐭 𝐈 𝐝𝐞𝐬𝐢𝐠𝐧: • Marketplace web and mobile app UI/UX • Directory and listing platform design • Search, filter, and sorting UX • Listing and detail page design • Booking and reservation flows • Buyer, seller, and admin dashboards • Vendor onboarding flows • Local business and service directories • Property and rental marketplace UX • Job board and talent marketplace UX • Lead-generation listing platforms • Mobile-first browsing experiences My background in real estate and PropTech gives me deep experience with listing-heavy products: property search, filters, maps, listing cards, comparison views, inquiry forms, booking flows, agent dashboards, lead capture, and CRM-style admin panels. I apply that same UX thinking across the full range of marketplace and directory products. The hard problems repeat across platforms: helping users search and filter without feeling overwhelmed, making listing cards scannable, surfacing the right details before a click, building trust on the detail page, supporting buyer, seller, and admin roles cleanly, and generating leads without an aggressive or confusing experience. 𝐌𝐲 𝐩𝐫𝐨𝐜𝐞𝐬𝐬: 1. Understand the product type, business model, and user roles. 2. Map the key flows — search, listing detail, inquiry, booking, onboarding, dashboard, and admin. 3. Structure information architecture so users find and compare options easily. 4. Wireframe to solve UX problems before visual design. 5. Design clean, modern high-fidelity UI in Figma. 6. Build responsive desktop and mobile layouts. 7. Organize components, cards, filters, states, forms, and dashboards for handoff. I focus on search usability, filter and sort clarity, listing-card hierarchy, map and list views, booking and inquiry flows, trust signals, mobile browsing, seller dashboards, admin-workflow simplification, empty, error, and loading states, lead capture, and conversion from visitor to inquiry, booking, signup, or purchase. Products I design include service marketplaces, rental and booking platforms, local-business directories, real estate and property portals, product and vendor marketplaces, job and talent boards, event directories, appointment-booking apps, community listing platforms, and SaaS marketplace dashboards. Clients usually come to me when a product has too many options, too many roles, or too much information on a single screen. I make those products easier to understand by separating user journeys, simplifying navigation, refining cards and filters, and making the primary actions obvious. My goal is to make every role feel clear. Buyers know how to search and choose. Sellers and vendors know how to manage listings and leads. Admins know how to monitor the platform. And the business gets a design that supports growth without becoming messy. Relevant expertise: marketplace UI/UX, directory website design, listing platform design, search and filter UX, booking platform design, rental and service marketplaces, vendor marketplaces, local business directories, property listing sites, real estate marketplaces, job boards, talent marketplaces, product marketplaces, marketplace web and mobile apps, buyer, seller, and admin dashboards, lead-generation platforms, map search, listing cards, detail-page UX, inquiry and comparison flows, Figma design, wireframes, prototypes, responsive design, and developer handoff. I work on early-stage ideas, live platforms, MVP redesigns, and focused feature improvements. If your marketplace feels cluttered, I'll help pinpoint why users aren't finding, comparing, booking, or contacting effectively. Tools: Figma, FigJam, user flows, wireframes, clickable prototypes, reusable components, design systems, and handoff-ready files. Bring me an idea, MVP, wireframe, product brief, existing site, or competitor examples — I'll turn it into a structured, scalable marketplace or directory design.
