Hi, I’m Serghei. I help startups, agencies, and businesses build production-ready web and mobile applications, from idea and architecture to backend development, deployment, and ongoing improvements. I specialize in Laravel, custom PHP systems, REST APIs, SaaS platforms, CRM systems, dashboards, and React Native mobile apps with Expo. I can help you with: • Building web applications from scratch • Developing backend systems and APIs • Creating SaaS platforms and subscription systems • Integrating Stripe payments and third-party services • Building React Native mobile apps • Improving, fixing, or extending existing projects • Creating clean and fast landing pages when needed Tech stack: • Laravel / PHP • MySQL / PostgreSQL • REST APIs • React Native / Expo • Stripe • SaaS architecture • CRM and dashboard development I’m comfortable working even when there is no full specification or design yet. I can help clarify the idea, suggest the right technical approach, and turn it into a working product. Whether you need a new product built from scratch or improvements to an existing system, I can quickly understand the requirements and deliver reliable, clean, and maintainable solutions.

Stop building just another feature. Start automating business outcomes. As a Top-Rated Full-Stack Engineer (100% Job Success) specializing in AI Automation, I bridge the gap between traditional MERN/Next.js development and cutting-edge LLM integration. I don’t just wrap APIs; I build secure, production-grade AI systems that save time, cut costs, and scale gracefully. WHY PARTNER WITH ME? 🔹 Beyond Basic Chatbots: I engineer autonomous AI Agents (LangGraph, LangChain, CrewAI, MCP) that execute complex, multi-step business logic and real-world tasks. 🔹 Data-Driven AI (RAG): I build robust Retrieval-Augmented Generation pipelines using Vector Databases (Pinecone, Supabase) so your AI answers reliably using your private data—with zero hallucinations. 🔹 Production-Ready Architecture: AI is useless if the core app crashes. I ensure seamless integration into robust Node.js and Next.js architectures with enterprise-grade security and multitenant authentication (Keycloak/SSO). 🔹 Human-in-the-Loop Safety: I implement strict guardrails and prompt security to keep your proprietary data protected and your operations reliable. CORE TECH STACK & EXPERTISE: 🧠 AI & LLMs: LangGraph, CrewAI, Custom Agent Workflows, Prompt Engineering, RAG Pipelines. 💻 Frontend: React.js, Next.js, TypeScript, UI/UX optimization. ⚙️ Backend & Databases: Node.js, Nest.js, GraphQL, PostgreSQL, MongoDB, Vector Databases. ☁️ Cloud & DevOps: Docker, Microservices, Stripe API, Keycloak, REST APIs. TYPICAL ENGAGEMENTS: ✔️ Custom AI Agents: Building multi-agent systems for lead generation, data extraction, or automated customer support. ✔️ Internal AI Knowledge Bases: Designing RAG systems to instantly query massive amounts of internal PDFs, contracts, or company data. ✔️ Legacy Modernization: Retrofitting your existing web applications with modern, AI-native capabilities. ✔️ Full-Stack Development: End-to-end development of scalable SaaS platforms from architecture to deployment. My goal is to deliver measurable ROI, not just lines of code. If you want a technical partner who communicates transparently and delivers on time, let’s talk. Send me a message to discuss your current bottlenecks, and let's map out an automation strategy that scales. --- 🚀 EXPLORE MY WORK Please view the Portfolio section below to see live interactive demos of my AI-native applications and my complete 6-year engineering showcase.

The original scope was simple: compare invoices against biweekly timesheets. But once I reviewed the actual workflow, the real problem became clear. The team was doing too much manual and unstandardized work before the verification step. The data was not always structured the same way, which created confusion, repeated checks, and too many edge cases for a verification tool to handle reliably. Instead of blindly building the first requested tool, I proposed a better automated workflow that standardized the process earlier and reduced the need for manual verification in the first place. The client saw the value immediately and asked us to move in that direction. That is how I work. I do not just build what is written in the task description. I look at the business process, identify where time and money are being wasted, and recommend the solution that actually makes sense.

𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 I take on production software, AI-assisted MVP rebuilds, prototype-to-production SaaS platforms, workflow automation, internal tools, RAG systems, and full-stack web applications. I work well with both clear technical scopes and early-stage business problems, helping turn requirements, workflows, and ideas into practical software that can be built, launched, and maintained. I do not disappear mid-project. I communicate clearly, document important decisions, think through edge cases, and build with handoff in mind so your business is not dependent on me forever.

If any of this sounds relevant, send me a message or book a quick consultation call. I will review what you're building, tell you honestly whether I can help, and point out where I would improve the system or avoid unnecessary build cost.

NOTE: I was Top Rated Plus with 100% job completion until my very last short job that didn't work out and She gave me 1 star...But please read all of my reviews to see my history. Hello, my name is Jay. I'm currently living in Tampa Bay, Florida. In 2018 I resigned from a long term, senior development position (10 years total. 9 of which were remote full time, and 1 year working in our Minneapolis office). I decided to move into freelancing and possibly freelance to permanent if I find the right opportunity. Beyond software development, my strengths are: Communication, Finding the Right Business Solutions & Delivering what the Customer and Users Expect. Since beginning software development, I've learned that consistent and clear communication is the main key to success in the completion of software projects. I've worked mostly in eCommerce, credit card processing, payment processing and hardware API integration, mobile Xamarin development, SQL Server programming & database design. Also, recently have completed a large Stripe integration. Most of my work, from a platform standpoint, has been in C#, VB.NET, ASP.NET Core, ASP.NET Web Forms, Blazor, Entity Framework Core & Xamarin. I've completed multiple large software projects on a freelance basis from the ground up. From specifications planning, programming & launching into production. The first of which led to my 10-year role at my previous job after the initial build was complete and in production. Please reach out to discuss your projects!

For startups and businesses that need real software fast, I build AI SaaS products that are ready to ship and built to grow. Give me an idea and I'll build it into a product real customers will pay for. That's my promise. If you send me a message or invite me to your job, I'll personally review your project and reply with a Loom video walking through exactly how I'd build it before we start. A little more about me. I build full-stack products for startups that need more than a basic website. Whether it's an AI SaaS MVP, a stuck project that needs rescuing, or a full platform with auth, payments, and dashboards ready on day one, I focus on systems that are clean, maintainable, and ready to scale. Some recent results: → Architected a Next.js and Node.js platform on AWS serving 10,000+ users at 99.9% uptime, with Stripe billing and a full admin dashboard. → Shipped a live AI bill-dispute SaaS with document analysis and role-based access that's serving paying users today. → Built an n8n automation with Twilio and OpenAI that cut a client's response time from hours to under two minutes. What separates me from a lot of freelancers is that I build real production systems, not quick prototypes that fall apart at scale. I ask sharp questions upfront so we avoid scope creep, I communicate daily so you always know where the project stands, and I recommend the architecture that saves you money long-term not the one that pads my hours. I work across the full stack: Next.js, React, and TypeScript on the frontend; Node.js, FastAPI, and Django on the backend; PostgreSQL and Supabase for data; OpenAI, Claude, RAG, and LangGraph for AI; and AWS, Docker, and GitHub Actions for deployment. I integrate Stripe, SendGrid, Twilio, Google APIs, and 400+ tools through n8n. If you're looking for someone who can properly build your product from start to finish or rescue one that's stuck, send me a message and let's talk.
