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.

I help ecommerce and service-based businesses turn paid ads into a predictable source of sales, qualified leads, and revenue growth across Meta Ads, Google Ads, and TikTok Ads. With 5+ years of paid advertising experience, a Master’s degree in Marketing, Meta Ads Certification, and 100+ completed client projects, I build and optimize full-funnel paid advertising systems focused on profitable growth, clean tracking, creative testing, and scalable performance. Most businesses do not struggle because they need “more ads.” They struggle because the full system is not working together: weak tracking, unclear campaign structure, poor creative testing, low-quality traffic, or a funnel that does not convert. My job is to find what is blocking growth, fix it, and build a paid ads system that can scale with confidence. What I can help you with: • Meta Ads campaign strategy, setup, optimization, and scaling • Google Ads Search, Shopping, Performance Max, Display, and YouTube campaigns • TikTok Ads campaign setup, creative testing, retargeting, and scaling • Ecommerce sales campaigns for Shopify and other online stores • Lead generation campaigns for service-based businesses • Full account audits to identify wasted spend and growth opportunities • Audience, competitor, keyword, and market research • Creative strategy, including hooks, angles, ad copy, UGC direction, and testing plans • Pixel, CAPI, GA4, GTM, UTM, and conversion tracking review • Retargeting and full-funnel campaign structure • Weekly optimization, reporting, and clear performance recommendations Common problems I help solve: • Ads are spending but not generating enough sales or leads • ROAS is unstable or too low • CPA is too high • Lead quality is poor • Tracking is inaccurate or incomplete • Campaigns lack structure and testing logic • Creatives are not converting or have stopped working • Google, Meta, or TikTok campaigns are not scaling profitably My approach: First, I review your current ads account, tracking, funnel, creatives, and offer. Then I identify where budget is being wasted and what needs to be fixed first. After that, I build or optimize your campaign structure, improve the testing process, and use real performance data to scale what works. I do not focus on vanity metrics. I focus on the numbers that matter: revenue, qualified leads, ROAS, CPA, conversion rate, and long-term profitability. Results my clients typically work with me for: • 2x–7x ROAS improvement • 20–40% CPA reduction • Higher add-to-cart, checkout, purchase, and lead conversion rates • Better lead quality and more predictable CPL • Clearer tracking and reporting • Stronger creative testing and campaign scaling process Why clients choose me: • I combine paid ads strategy with real marketing and business thinking • I understand both performance data and creative psychology • I can work across Meta Ads, Google Ads, and TikTok Ads, not just one channel • I make tracking and reporting clear, so decisions are based on real numbers • I communicate proactively and explain what is happening in the account • I focus on sustainable growth, not short-term hacks If you are looking for a paid ads specialist who can audit your current setup, improve your campaign performance, and build a clear strategy for growth across Meta, Google, and TikTok, send me a message. I can review your account and show you where the biggest opportunities are. Last updated at 05.08.2026

⭐ Senior Full Stack Developer | 50+ Products Shipped ✉️ 𝗠𝗘𝗦𝗦𝗔𝗚𝗘 𝗠𝗘 I typically respond within 12 to 24 hours, and urgent projects can be prioritized. I lead a senior engineering team that builds, scales, and rescues complex web and mobile products. Whether you need a single Senior Full-Stack Engineer or a dedicated team that plugs in and ships from day one – we move fast and deliver production-grade results. Over 50+ completed projects, we've helped startups and scale-ups go from prototype to release, and stepped in as the core engineering team when products needed to grow. We work primarily with Node.js and Nest.js on the backend and React / Next.js on the frontend – the same stack that powers most modern, high-load SaaS platforms. 🎯 WHAT YOU GET WHEN YOU HIRE US – 100% completion rate – every project delivered, backed by a 100% Job Success Score across 6000+ hours on Upwork – Fast start & team scaling – we onboard in days, not weeks, and scale the team up or down as your roadmap demands – AI-accelerated delivery – we integrate AI tools into our development process to improve code quality and ship faster – Full cycle – from prototyping and UX to architecture, development, and release 🏆 RESULTS "I highly recommend Pavlo - he will be my goto next time for any work like this. He understood exactly what I needed and was really fast to act. One of the best freelancers Ive used on Upwork!" – Lauren B., Client "Pavlo and his team were highly responsive, professional, and extremely efficient in diagnosing issues and identifying the root causes of several problems in the codebase. Their debugging process was structured and precise, and their recommendations during the code review were very valuable in improving the overall stability, performance, and maintainability of our system." – Client, Product Manager, SaaS Platform SELECTED PROJECTS – CaJu AI – an enterprise AI platform with real-time AI workflows, scalable Node.js backend services, and React-based interfaces for compliance-focused customer support automation. – CookieFirst – a large SaaS platform where we became the core engineering team, scaling the product, expanding functionality, and improving performance. – Ragusa Express – a booking platform with online reservations, payments, backend modernization, and React frontend improvements. TECHNICAL STACK Backend: Node.js, Nest.js, Express.js, Laravel, Symfony (TypeScript, PHP, Python) Frontend: React, Next.js, Vue.js, Tailwind CSS, SCSS/Sass Mobile: React Native, Java, Kotlin, Swift Cloud & Tools: AWS, Docker, NGINX, Supabase, PostgreSQL, MongoDB, DevOps, Figma If you're looking for a reliable Senior Full Stack partner who works in Node.js, Nest.js, and React and can take ownership from idea to launch – send me a message and tell me about your project. ENGAGEMENT MODELS You can bring on a single Full Stack Developer for focused feature work, a dedicated Backend Developer to own your Node.js services, or a full pod combining Full Stack Developer and Backend Developer roles with a React specialist on top. Most clients start with one Full Stack Developer or one Backend Developer and scale up once trust is established – we've grown from a single Node.js Backend Developer to an eight-person team on more than one long-term engagement. WHY NODE.JS AND REACT We standardized on Node.js and React because they let a single Full Stack Developer move across the stack without context-switching, and they give a Backend Developer and a React engineer a shared language when APIs and UI need to evolve together. A Node.js Backend Developer on our team typically ships REST or GraphQL services that a React frontend consumes within the same sprint, which is the main reason clients hire a Full Stack Developer from us instead of stitching together separate backend and frontend contractors. A FEW THINGS CLIENTS ASK BEFORE HIRING Can I hire just one Backend Developer? Yes – many engagements start with a single Backend Developer handling Node.js architecture while we hold a Full Stack Developer in reserve for later. Do you offer a trial period? Yes, a short paid trial with one Full Stack Developer or Backend Developer is the easiest way to check fit before scaling the team. Can you work backend-only? Yes – some clients only need a Node.js Backend Developer, others need a full Full Stack Developer team covering React end to end. Whether you need a Full Stack Developer or a Backend Developer, message me with your stack and timeline and I'll match you with the right Full Stack Developer from the team within 24–48 hours. Best regards, Pavlo Jedi at Red Carlos Solutions
