Hello, I'm Jayen Ashar, Sydney, Australia.
"Force Multiplier." Experienced tech startup founder (since 2013) and software developer (since the 1900s), helping non-technical founders test the market by building the leanest possible marketplace on Sharetribe. I specialise in two-sided markets. I'll tell you when Sharetribe isn't the right fit and when you're overbuilding. --- 30+ Sharetribe marketplaces launched across service, product, and booking models. Repeat clients across Australia, US, UK, and Europe. Expert-vetted on Toptal (top 3%) and Upwork (top 1%, 100% Job Success Score). I use AI extensively in my development workflow -- multiple AI coding tools cross-reviewing each other's work -- which means faster delivery without compromising quality. --- What clients come to me for: - Stripe Connect deep expertise: separate charges & transfers, partial refunds, cancellation policies, payout timing, and alternative payment processors like PayPal. - Shipping integrations: Shippo (labels, rates, tracking), Sendle, ShipStation, configurable pickup/delivery options. - Identity verification: Persona, Didit. - Third-party integrations: Nylas (calendar/email), Twilio (SMS/chat), SendGrid (email), Jitsi (video), Voucherify (vouchers), OpenAI, and more. - Reverse proxy setups: WordPress/Webflow + Sharetribe on the same domain. - Taking over codebases from other developers or agencies. - MVP scoping and lean launch strategy: what to build first, what to skip entirely, and when to use no-code instead of custom code. --- What clients say: "I've seen many different plans from other Sharetribe Expert Developers. It is clear you take a path of least resistance approach which I sincerely appreciate. I don't like to overinvest in unnecessary work and it is clear you don't like waste either." -- B2B marketplace founder, US "Everyone has been impressed with the solution's scope and capabilities. Kudos to you and your work on customizing the platform." -- B2B marketplace founder, US "You're providing valuable assistance beyond just entering code." -- B2B marketplace founder, US "He did a great job. You can trust him. He's really good." -- Lead developer, art marketplace "What really spoke to me, you put that minimal viable product concept in. That's 100% a technician. I know that's exactly what I need." -- Agency partner, Australia "It's fantastic, great work. You made amazing progression." -- Marketplace founder, Australia "You're 100% correct. Great detective work!" -- E-commerce marketplace founder, US "Thanks for jumping on and helping me and calming my nerves." -- Marketplace founder, Australia --- AUD 199/hr (~USD 139/hr).
