There is a specific kind of web development that many engineers avoid the kind where the software must scale seamlessly under heavy usage, integrate with complex APIs, handle sensitive business data, and still deliver a polished, intuitive experience for clients and end-users alike. That is exactly the intersection I have built my career in. With 8+ years of full-stack development experience, I have shipped Healthcare SaaS platforms, multi-tenant marketplaces, internal dashboards, and scalable web applications that grow with your business. Each project demanded a level of technical depth and product precision beyond generic web app development. Healthcare SaaS is where my experience is most focused. I have worked on patient management systems, telehealth platforms, and healthcare operations dashboards designed to handle sensitive patient data and support high-traffic production environments. These systems are typically built around strict access control, audit logging, and healthcare-oriented data workflows to ensure reliability and data integrity. In these applications, I have integrated scheduling systems, EHR-style workflows, secure messaging between patients and providers, as well as third-party services such as payment gateways, insurance-related billing flows, and external healthcare APIs. Across these projects, I have consistently applied compliance-aware architecture principles, including role-based permissions, encrypted data handling, and structured audit trails to support healthcare-grade requirements and operational transparency. ► Complex Web Workflows: • Multi-role dashboards for agents, managers, and clients with dynamic permissions • Real-time chat, notifications, and task workflows to streamline operations • Integrated payment flows with Stripe and PayPal, including subscription models and usage-based billing • Analytics pipelines to track engagement, property trends, and lead conversion metrics ► Scalable & Optimized Architecture: • Server-side rendering and static generation in Next.js for speed and SEO • API design using GraphQL, REST, and WebSockets for live updates • Cloud-based solutions leveraging AWS, Firebase, and Supabase • CI/CD pipelines using GitHub Actions and automated deployment workflows ► Tech Stack: • Frontend(SaaS Product Layer): Next.js, React, TypeScript, TailwindCSS, Chakra UI • Backend(MVP & API Layer): Node.js, Express, NestJS, Python, FastAPI, Serverless Functions • SaaS Data Layer(Multi-tenant ready systems): Supabase, MySQL, PostgreSQL, MongoDB, data modeling for SaaS products • DevOps & Scaling(Production-ready MVPs): Vercel, AWS, Netlify, Docker, GitHub Actions, CI/CD pipelines • Product Integrations (Revenue & Growth systems): Stripe billing, third-party APIs, auth systems (JWT, OAuth), analytics tools If you are building a Healthcare SaaS platform, marketplace, or any scalable web app and need an engineer who has shipped full-stack solutions end-to-end, not just studied them , let’s talk. I am selective about the projects I take on, and I’d be glad to review your requirements and tell you exactly how I’d approach your MVP or product launch. ► Keywords: Healthcare SaaS Development, Property Management Software Development, MLS Integration & IDX Integration, Multi-Tenant SaaS Architecture, SaaS MVP Development, Full-Stack Web Development, Next.js Development, React.js Development, TypeScript Development, Node.js Development, NestJS Development, Serverless Application Development, API Development & Integration, REST API Development, GraphQL API Development, WebSocket Real-Time Applications, Dashboard Development, Admin Panel Development, CRM Integration, Stripe Payment Integration, PayPal Payment Integration, Subscription-Based SaaS Platforms, Property Analytics Dashboards, Lead Management Systems, AI-Powered Recommendation Systems, Predictive Analytics Applications, Healthcare Lead Scoring Systems, AWS Cloud Development, Supabase Development, Firebase Development, PostgreSQL Database Design, MongoDB Development, Docker Deployment, CI/CD Pipeline Development, GitHub Actions Automation, SEO-Friendly Web Applications, Server-Side Rendering (SSR), Static Site Generation (SSG), Responsive Web Design, Progressive Web Applications (PWA), Enterprise Web Application Development, Marketplace Platform Development, Business Process Automation, SaaS Product Architecture, Scalable Web Application Development, Startup MVP Development, Product Engineering, Cloud-Native Application Development, Data Privacy & GDPR Compliance, Secure Authentication & Authorization, Technical Architecture Consulting

I build go-to-market systems, not automations in isolation. My work sits at the intersection of GTM strategy, outbound engineering, and AI-driven execution. I help companies move from vague ICP assumptions and manual prospecting to instrumented, testable, and scalable GTM engines. AI and automations are not the product. They are the force multiplier. What I focus on - ICP & persona engineering (who to target, and why) - Outbound system design (data → enrichment → routing → messaging) - Hypothesis-driven GTM experiments (what actually converts) - AI decision layers that replace analyst judgment, not just effort What I’ve built (real GTM work): 1. Outbound ICP testing framework: Designed and executed multi-hypothesis LinkedIn outreach across 300 companies → Winning ICP delivered 4.17× reply-rate uplift and 48% positive responses 2. AI-powered investor & partner targeting: Built screening systems for fundraising and strategic outreach → 500 targets → 48 validated, high-intent investors with 87% AI accuracy 3. Sales pre-call intelligence pipelines: Automated lead research → structured briefings → CRM ingestion → Eliminated manual prep while improving call quality Market & M&A list-building architectures: Automated market scans using scraping + AI qualification → Hours of analyst work compressed into minutes

Hi, I'm Karol! 👋 My lead gen & content strategies secured a partnership with a 9-figure tech enterprise: → Saved ExpressVPN ~$4k in ad spend by driving 30k+ targeted organic views. → Designed AI roadmaps for 3 B2B firms to eliminate $54k/year in manual waste. → Generated 60k+ targeted views for an e-commerce brand from one campaign. The longer, sit-down version (if you've got a minute): Pleasure to meet you! I'm Karol 👋. I help businesses find more customers and save time by building smart AI systems. I use the best tech out there, like Claude Code, n8n, Vapi, and Retell AI. I've audited and created custom roadmaps for traditional B2B businesses to modernize their operations. My favorite systems to build include: - Cold Email & Lead Gen Infrastructures (to magically source leads, perfectly set up DNS/deliverability to bypass spam, and reach out using automated, high-converting sequences). - Voice AI Receptionists & Sales Reps (to automatically handle inbound calls, qualify leads, answer FAQs, and book appointments directly into your calendar 24/7). - Workflow & B2B Automations (to fully automate internal bottlenecks, sync CRMs, and route leads seamlessly from the first touch to a closed deal). I also have experience integrating various CRMs and project management tools (think HubSpot, Salesforce, etc.) to ensure your new systems talk to each other perfectly. If you want someone who loves building smart tools that help you make more money, I’m your guy. Whether you need a simple email setup or a smart AI that talks to your customers, I will do a great job and keep you updated every step of the way. Looking forward to meeting you!
