𝐓𝐨𝐩 𝟏% Senior Full Stack Developer (expert vetted by Upwork).
My services have helped my clients launch Software Businesses with over $𝟏𝟎𝐌𝐢𝐥𝐥𝐢𝐨𝐧+ Evaluation.
I help Entrepreneurs in the US launch 𝐒𝐨𝐟𝐭𝐰𝐚𝐫𝐞 𝐁𝐮𝐬𝐢𝐧𝐞𝐬𝐬𝐞𝐬 with more that $100k ARR
🌟 My Clients are Launching Products in 𝟑-𝟒 𝐰𝐞𝐞𝐤𝐬 and going live in a Month.
💚 I cannot help everybody, but we may be a great fit if you are thinking:
"There's millions on the line and I want the BEST"
"I know my business I have the customers, but I dont understand Code"
"I'm NOT a coding expert, and I don't have time to mess around with code!"
"The last Saas we built was embarrassing - I don't want that EVER again"
"I need a full Saas Develpment Package that I KNOW 100% will work RIGHT"
I focus on B2B Saas Products that aim $1M ARR
Working with me, you will
★ Stop struggling with tech - I handle the Saas Planning, Design, Development, Marketing, Strategy Architecture, Market Research, Design & Pitch Strategy
★ Put your best foot forward for your one shot with Saas Market.
★ Anticipate Client objections and pre-handle them
★ Receive turnkey, investor-grade, futureproofed Saas product
★ Captivate investors with the Full Working MVP
...and even save money by taking my high-quality work and reusing previously created work and not re-inventing the wheel.
Not everyone is my client, though. Some signs we might not be a good fit include:
✗ The company is only looking to make a quick buck and isn't interested in creating a valuable long-term product.
✗ The company doesn't have a realistic budget to execute their SaaS idea.
✗ The company is only interested in getting information and isn't committed to seeing the project through to completion.
I have built my own 100ARR Saas Products successfully. I’ve also been an investor, advisor and director – and now I run our inhouse Saas - so I’ve got a 360 view of the Saas Market.
🔢 My stats:
● $10M+ generated for Client Software revenue
● Clients generated $10K/month in 2022 on avg
● Over 56+ Saas Products built
