Are you looking for a 𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿 who actually gets things done?
I'm Artem. I've been building web products for years — React, Next.js, Node.js, TypeScript — the full picture, frontend to backend. Not "I touched React once" kind of experience. Real production systems, real users, real scale. I built and scaled Yumzi.app to 10,000+ restaurants. That kind of thing.
𝗛𝗼𝘄 𝗜 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝘄𝗼𝗿𝗸:
I don't wait around for someone to explain every detail. I jump into the codebase, understand the architecture, ask the right questions, and start moving. If something in the project doesn't make sense technically — I'll tell you honestly instead of just building it the wrong way.
I care about the product, not just the ticket. So if I notice something broken or a better approach while working on your project — I'll bring it up. That's just how I operate.
𝗪𝗵𝗮𝘁 𝗜 𝘄𝗼𝗿𝗸 𝘄𝗶𝘁𝗵:
𝗙𝗿𝗼𝗻𝘁𝗲𝗻𝗱: React, Next.js (App Router), TypeScript, Tailwind CSS, Shadcn/ui, Framer Motion, Redux, Zustand
𝗕𝗮𝗰𝗸𝗲𝗻𝗱 𝗮𝗻𝗱 𝗗𝗮𝘁𝗮: Node.js, NestJS, Prisma, PostgreSQL, Supabase, Firebase, REST/GraphQL
𝗔𝗜 𝗮𝗻𝗱 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀: OpenAI API, Claude, Grok, Stripe, DLocal, Twilio, SendGrid
𝗧𝗼𝗼𝗹𝘀: Git, Vercel, Docker, Figma to code
I'm open to both — long-term product work where I become a core part of your team, or shorter engagements like MVPs, new features, or performance problems nobody else wants to debug.
Send me a message, let's talk about your project.

Still stuck at we need to hire a developer? Message me. I ship Next.js + React SaaS MVPs for founders in 4–6 weeks AI features, Stripe billing, multi-tenant auth, Node.js + TypeScript, Figma → live.
Here’s what most founders learn too late: many developers can build screens, but very few have shipped SaaS products that real customers actually pay for.
Over the last 7 years, I’ve helped founders launch production SaaS platforms with live Stripe billing, real user onboarding, active subscriptions, and revenue coming in. One MVP I built helped a founder scale to $40K MRR within 6 months. Another was strong enough to support a seed-round demo.
I don’t build code just to pass a review or look good in staging. I build products that are clean, usable, scalable, and ready for someone to actually pay for.
𝐖𝐡𝐚𝐭 𝐈 𝐒𝐡𝐢𝐩:
→ Founder MVPs in 4–6 weeks (Next.js, React, Node.js, TypeScript)
→ AI SaaS features chat, automation, workflows, dashboards
→ Stripe billing, auth, admin panels, multi-tenant setup
→ Figma → production code (pixel-perfect, mobile-first)
→ Vercel / AWS deploy with CI/CD
𝐖𝐡𝐲 𝐂𝐡𝐨𝐨𝐬𝐞 𝐌𝐞:
✅ 100% Job Success · Top Rated · US-based (Jacksonville, FL)
✅ MSCS + Marine discipline → I hit deadlines like I hit ranges
✅ 4hr response · daily Loom updates · no ghosting
✅ I turn down 3 of 4 jobs if I say yes, I mean the timeline
✅ Fixed-scope, fixed-timeline builds no scope creep surprises
📩 𝐒𝐞𝐧𝐝 𝐌𝐞 𝐎𝐧𝐞 𝐋𝐢𝐧𝐞:
Tell me what you're building and who it's for. That's it. Within 4 hours you'll have back the exact stack, a real 4–6 week timeline, and an honest yes-or-no on whether I can ship it. No pitch deck. No discovery call. No BS. Just the answer you came to Upwork for.
Your move.

If you need a custom app built from scratch — or you’re stuck with a half-finished codebase from a previous developer — I can help you move it forward without unnecessary rewrites.
I’m Adrian, founder of Peer Concept, a small software development team. Clients work directly with me, and I bring in my team when the project needs extra frontend, backend, DevOps, QA, or UI/UX capacity.
Most of our work comes from two situations:
- founders building a product from zero
- teams stuck with an unfinished or messy app that needs to move forward
What we build and fix:
- custom web applications using React, Next.js, Angular, Node.js, Django, FastAPI, and .NET
- mobile apps with React Native
- REST APIs and third-party integrations: payments, CRMs, internal tools, external platforms
- AI features using OpenAI, Claude, LLM APIs, automation workflows, and custom AI tools
- existing app takeovers — we read the code, understand the system, and continue development
- end-to-end delivery: scope → build → deploy → maintain
Relevant examples:
- AuctionForecast — took over a data-heavy wine auction platform after multiple developers and continued development without a rewrite
- Firefly — built an AI compliance monitoring system that analyzes customer communications and risk signals
- DrForms — developed an AI medical documentation app that turns doctor-patient audio into structured reports
- MyKidsTales — built an AI storytelling platform with personalized story generation
- Blue Mountain Loans — built a consumer lending platform with application, e-signature, direct deposit, payment-processing, and risk-scoring API integrations
Recent client feedback:
“Adrian did a great job on our loan platform. We had multiple API integrations and a complex flow, and he handled everything smoothly.”
We don’t take every project. But when we do, we focus on clear communication, stable delivery, and shipping working software.
Send me a short description of what you’re building or trying to fix, and I’ll tell you within 24 hours if we’re a good fit.

Most AI SaaS products work well in demos but struggle under real-world usage. I build production-grade systems that scale reliably, handle edge cases, and meet the security and compliance requirements of regulated industries.

- Cloud Deployment (AWS, DigitalOcean, Vercel)
Beyond Development :
I don't just build what's requested, I help identify the most effective technical solution before development begins. With 8+ years of experience leading architecture decisions and supporting founders as a technical partner, I focus on balancing speed, scalability, and business goals.
Proven Results :
Healthcare Infrastructure :
→ Built an HL7 gateway for HealthMosaic, endorsed by the VP of Enterprise Solutions at Fukuda Denshi USA.

→ Cloud & DevOps: AWS, Docker, Kubernetes, CI/CD
→ Healthcare & Compliance: HL7, FHIR, HIPAA-aware architectures, Audit Logging

"I had a very good experience with Taj and his team. We worked on an early phase MVP that we were able to bring to life and I look forward to working with them again in the future."
"Tajinder was great to work with. He is easy to communicate with and explains everything in clear, simple steps, which made the whole process smooth. He is transparent, honest, and puts in genuine hard effort.
If you're building in AI, healthcare, fintech, or any SaaS where it has to work the first time, send me what you're building.

During my time at Sony, I helped build some of the highest traffic fan experiences for global sports teams and associations. A highlight of my time there was building the video portal for the ICC Cricket World Cup 2019. This portal received over 1 billion video views in the space of 14 days, which was a testament to the best practices we followed while developing.

Why you’ll wish we started working earlier together:
✅ Transparency and visibility is core to the way I work. You can expect access to JIRA, GitHub and Trello where I track our projects and code so you can see your vision come to life in real time.
✅ I have a deep focus on wireframing and prototyping. This way both me and you will have a clear understanding of what we are going to build. 90% of projects fail due to a lack of communication at this stage and I believe this is something that I have mastered.
✅ I write readable maintainable and well documented code that can easily be taken over by an internal development team. If you are not ready to hire a team, We can work as a dedicated team of developers to maintain and enhance your product.
