We needed help for two weeks, and Tolik stepped in and closed the gap. It was great working with him - he delivered early despite a very tight deadline. He’s a true professional with outstanding web development skills and a strong grasp of the business side, which makes working with him a pleasure. Highly recommend.

Fix Authentication Issue With JWT Token
Tolik has been instrumental in solving some challenging back-end coding issues. He has been very responsive, is technically adept and has turned around with the deliverables required very quickly. I would highly recommend his services for issues related to dot net code, server set-up, JWT token issues as well as database upgrades. Am extremely satisfied with his work.

Tolik was an outstanding member of the development team. He was able to jump in and contribute immediately to the project which allowed us to make significant progress on our backlog. Tolik asked insightful questions to ensure the requirements were understood and worked efficiently to meet deadlines. Tolik provided daily updates in Slack and Jira which was very helpful for the project manager. Highly recommend Tolik as a developer, especially if you need a dedicated, full-time resource.

Job Success
Bayonne, United States - 8:15 pm local time
I'm a Full Stack Developer and SaaS Developer. I've shipped 14 SaaS products, most of them long-term projects where I owned the architecture, not just the code.
My preferred stack is React, Next.js, Node.js and TypeScript. For data, PostgreSQL or Supabase, depending on the project. Supabase is my go-to for startups to move fast. For bigger builds, I design the backend on AWS.
What I build most often:
✧ SaaS platforms with multi-tenant architecture, auth, and role-based access
✧ B2B marketplaces - vendor onboarding, listings, search, order flows
✧ MVPs for startups that need to launch, not sit in planning
✧ Stripe billing, including messy multi-tier subscription setups
✧ Admin dashboards and CRM tools that make sense of your data
✧ AI-powered features with OpenAI and Claude - but only where they actually help
I've worked across fintech, e-commerce and construction tech. Different industries, same pattern: someone has outgrown their current setup and needs real software. A lot of clients arrive after hitting the ceiling with WordPress or no-code tools. I migrate them in phases, so nothing breaks along the way.
Speed matters, so I don't start from zero. I have my own SaaS Kit - auth, billing, admin panel, AI - all pre-built and battle-tested. It cuts weeks off any MVP. Free for my clients.
And you'll always know where things stand. I send regular updates, spot problems early, and never disappear mid-project. Ask any of my long-term clients - most of them started with one small task.
Launching a startup? Building a marketplace? Or stuck with a platform showing its age? Message me for a free 15-minute call. I'll tell you straight if I'm the right full stack SaaS developer for your job.
