Optimize Website Performance & Reduce Database Hosting Costs for Custom Built Vercel Site
Shah was professional, patient, and solutions-focused throughout our Thankly website rebuild. The project became more complex than expected due to our legacy setup, but Shah handled every challenge calmly and thoughtfully. Communication was clear and consistent, and we’re proud of the final result. We’d happily work with Shah again and recommend him to anyone needing a reliable, problem-solving developer.

I'm a 𝗪𝗵𝗶𝘁𝗲-𝗟𝗮𝗯𝗲𝗹 𝗗𝗲𝘀𝗶𝗴𝗻 & 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 𝗣𝗮𝗿𝘁𝗻𝗲𝗿 for agencies and a direct technical partner for individual founders and businesses who'd rather hire one specialist than coordinate five.
𝗙𝗼𝗿 𝗮𝗴𝗲𝗻𝗰𝗶𝗲𝘀: I work entirely behind your brand. Your clients see your name on every deliverable, email, and invoice, I stay invisible. You scope the project, I execute it, you deliver it. No subcontractor disclosures, no awkward handoffs.
𝗙𝗼𝗿 𝗶𝗻𝗱𝗶𝘃𝗶𝗱𝘂𝗮𝗹𝘀 𝗮𝗻𝗱 𝘀𝗺𝗮𝗹𝗹 𝗯𝘂𝘀𝗶𝗻𝗲𝘀𝘀𝗲𝘀: same skillset, direct delivery, no agency markup in between.
𝗦𝗽𝗲𝗰𝗶𝗮𝗹𝗶𝘇𝗶𝗻𝗴 𝗶𝗻 ✅ 𝗖𝘂𝘀𝘁𝗼𝗺 𝗪𝗼𝗿𝗱𝗣𝗿𝗲𝘀𝘀 & 𝗪𝗼𝗼𝗖𝗼𝗺𝗺𝗲𝗿𝗰𝗲 ✅ 𝗦𝗵𝗼𝗽𝗶𝗳𝘆 ✅ 𝗚𝗼𝗛𝗶𝗴𝗵𝗟𝗲𝘃𝗲𝗹 (𝗚𝗛𝗟) ✅ 𝗖𝗮𝗹𝗰𝘂𝗹𝗮𝘁𝗼𝗿𝘀 & 𝗤𝘂𝗶𝘇𝘇𝗲𝘀 ✅ 𝗔𝗜 𝗔𝗴𝗲𝗻𝘁𝘀 ✅ 𝗥𝗲𝗮𝗰𝘁.𝗷𝘀/𝗡𝗲𝘅𝘁.𝗷𝘀 & 𝗠𝗘𝗥𝗡 𝗦𝘁𝗮𝗰𝗸 ✅ 𝗥𝗲𝗮𝗰𝘁 𝗡𝗮𝘁𝗶𝘃𝗲 ✅ 𝗔𝗣𝗜 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀
🔹 𝗪𝗼𝗿𝗱𝗣𝗿𝗲𝘀𝘀 & 𝗪𝗼𝗼𝗖𝗼𝗺𝗺𝗲𝗿𝗰𝗲: Custom builds, redesigns, and stores using Elementor, ACF Pro, and Gutenberg, with Core Web Vitals optimization and ongoing maintenance.
🔹 𝗦𝗵𝗼𝗽𝗶𝗳𝘆: Custom theme development and store builds for ecommerce clients who've outgrown a template.
🔹 𝗚𝗼𝗛𝗶𝗴𝗵𝗟𝗲𝘃𝗲𝗹 (𝗚𝗛𝗟): CRM setup and migration, pipeline and automation design, calendar/booking workflows, white-label sub-account configuration for agencies reselling GHL to their own clients.
🔹 𝗖𝗮𝗹𝗰𝘂𝗹𝗮𝘁𝗼𝗿𝘀 & 𝗤𝘂𝗶𝘇𝘇𝗲𝘀: Custom pricing/cost estimators and lead-gen quizzes, built in vanilla JS or React so they work on any platform — not locked to a quiz plugin.
🔹 𝗔𝗜 𝗔𝗴𝗲𝗻𝘁𝘀: Agentic workflows and chatbot integrations tied into a client's existing site, CRM, or support stack: qualification bots, automated follow-up, internal tooling.
𝗔𝗹𝘀𝗼 𝗮𝘃𝗮𝗶𝗹𝗮𝗯𝗹𝗲: React/Next.js and MERN stack development, React Native for hybrid mobile apps, and API integrations for projects that need custom engineering beyond what a CMS or no-code platform can deliver.
𝟭,𝟵𝟬𝟬+ 𝗰𝗼𝗺𝗽𝗹𝗲𝘁𝗲𝗱 𝗨𝗽𝘄𝗼𝗿𝗸 𝗽𝗿𝗼𝗷𝗲𝗰𝘁𝘀, with experience across automotive, pharma, and consumer-goods enterprise clients (named on request, NDA-permitting). Response time under an hour during business hours.
If you're an agency that needs a build partner who won't show up in your client's inbox, or a business owner who needs one person to own the technical side end to end, send me the brief and I'll tell you honestly whether it's a fit.
