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. --- Who does the work: Three of us work under this profile. I do the technical architecture and the hard builds. Adam and Tim do most of the rest, and I'm responsible for their work. Adam has built Sharetribe marketplaces with me for years, including Stripe Connect and ShipStation integrations and taking over code from other agencies. Tim joined more recently. Both are Australian and native English speakers. Adam is in Sydney. Tim works remotely. You talk to your developer directly. There is no project manager in between. --- 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 with me (~USD 139/hr), AUD 79/hr with Adam, AUD 59/hr with Tim. I estimate each task before starting.

Jayen is a true 10x engineer with expert-level knowledge of Sharetribe and its internals. What makes him particularly valuable, though, is that he understands the business requirement behind the development request. Rather than simply implementing what I ask for, Jayen identifies multiple ways to solve a problem, explains the tradeoffs, and helps determine the right approach for the business. He’s a full-stack developer who can rapidly prototype an idea, but he can also take on major, business-critical engineering work. Most recently, he led a major overhaul of our payments platform. Just as importantly, Jayen genuinely cares about the product and getting things right. When something goes wrong—even an intermittent or difficult-to-reproduce issue—he takes ownership and tracks it down rather than settling for an easy explanation or workaround. I’ve also worked extensively with Adam through Jayen and have been very happy with the quality of his work as well. This combination of deep Sharetribe-specific expertise, full-stack capability, speed, business judgment, and genuine ownership is extremely difficult to find. I would absolutely recommend Jayen and his team for any organization looking to deploy and extend Sharetribe. Posted by Sharetribe on behalf of the Pewcentric team

I worked with Jayen on a year-long project. He is pleasant, attentive, and deeply knowledgeable in his field. He thinks as an owner throughout each workstream, not just an advisor or consultant. He will always be on the top of my list for advice and insights. I highly recommend Jayen. Posted by Sharetribe on behalf of Brian Iversen

We have had a positive experience working with Jayen From the beginning, he has been quick to respond, very easy to communicate with and super reliable. He has always been patient with us especially when we find it difficult to understand the technical side of things and will always take his time to explain everything without making it feel complicated. Jayen is very approachable and always tells us to send him a email whenever we want and he will get back to us almost straight away; he provides us with helpful suggestions and works with us to find the best solutions rather than simply completing the task and moving on. It can be overwhelming at times when building a platform, but having someone who is responsive, knowledgeable, and patient has made the process easier. Would highly recommend Jayen to anyone looking for a dependable and professional developer Posted by Sharetribe on behalf of a founder who preferred to stay anonymous

Working with Jayen has been an excellent experience. He delivers his work rapidly, is clear with his communication, and finds opportunities for improvements without asking.

I really appreciated how Jayen approached our collaboration. I was just getting my business started and I did not have a large budget. Jayen processed my requirements and carefully outlined variables like complexity, cost, time, and need. He demonstrated his marketplace business expertise sharing his thoughts on the necessity of certain features. I was able to identify my immediate priorities. Jayen was able to deploy features in our agreed upon timeline. When there were small fixes I identified in tested, he quickly made the updates. Jayen showed his flexibility to build features within my constraints. He was a thought partner, not just a builder. I received excellent reviews from my stakeholders who were pleased with the initial feature-set. I looking forward to continuing our collaboration as my marketplace grows.

He is an excellent developer: fast, reliable, and very professional. He delivers high-quality work on time, communicates clearly, and is always quick to solve any issues. Highly recommended.

Working with Jay has been great. As a young marketplace with no professional technical experience his help has been invaluable, as he was always available to help designing the feature and he would provide great business-aware advice. Posted by Sharetribe on behalf of the RoofWander Team

I’ve been working with Jayen and Adam on the development of SaferFaces, and they have been nothing short of amazing. Beyond the actual development work, they’ve provided genuinely valuable strategic advice that has helped me make better technical decisions and think more clearly about how to give the platform the best chance of success. As a non technical founder, it’s been incredibly helpful to have a team that not only understands the build, but also takes the time to explain the thinking behind key decisions. Their input has given me a much stronger footing and a clearer path forward. I’m genuinely very happy with the work they’ve done and the way they’ve supported the project so far. I’d highly recommend them to anyone looking for development support, especially if you’re building a marketplace or working with Sharetribe. They deserve real recognition for the quality of their work and the care they put into helping founders succeed.
