When you partner with me, you get production-ready AI systems that automate real workflows, cut operational costs, and put your data to work not prototypes that stall before launch. CORE STRENGTHS LLM Integration: OpenAI, Claude, Gemini, and open-source models wired into real products, not demos RAG Systems: retrieval pipelines with vector databases (Qdrant, Pinecone, Weaviate) for accurate document Q&A and semantic search AI Agents: autonomous systems with multi-step reasoning, tool calling, and API execution Production Deployment: AWS, Docker, and CI/CD for reliable, maintainable systems Business focus: every build ties to a measurable outcome — lower response times, reduced manual work, faster retrieval ABOUT ME I'm a backend and AI engineer with 7+ years of professional experience building systems that solve real business problems. My work spans large language models, RAG, and full-stack Python development. At TalentPop I led AI initiatives across property tech and customer-service automation, shipping production systems used daily by real teams. My approach pairs solid engineering with business sense I want to understand the outcome you're after before I write a line of code. SERVICES I DELIVER LLM Integration & RAG Systems: Retrieval-Augmented Generation pipelines combining vector databases with language models for accurate document Q&A, knowledge retrieval, and context-aware responses.

I provide a Node.js Backend Developer team that ships production-grade SaaS, APIs and platforms. 11,000+ hours worked, 50+ Node.js Backend Developer projects delivered, 100% Job Success Score, Top Rated Plus. As CEO I scope and own every Node.js Backend Developer engagement we sign. I study the brief, run discovery with founders, match the right engineers and stay accountable for delivery. My team owns the code - I never touch it. So when a brief lands for a Backend Engineer, an API Developer or a full stack software engineer, I scope it and the team builds it. Why hire my team: - 20+ years of Node.js Backend Developer, Full Stack Developer and SaaS Developer delivery - 200+ Node.js Backend Developer and SaaS Developer projects shipped - Long-term clients on retainers (3 - 10+ years) Our Node.js Backend Developer team designs services, REST and GraphQL APIs, queues and event pipelines that hold up under real production load. A NestJS Developer on the team treats Node as a serious production runtime and owns the heavy backend modules. Typical engagements: multi-tenant SaaS APIs, real-time platforms, billing flows, data pipelines, AI-backed services. Stack: Node.js, NestJS, ExpressJS, TypeScript, PostgreSQL, Redis, Elasticsearch, AWS, GCP, Docker, Kubernetes. Our Full Stack Developer team owns systems end-to-end - one team handling Node.js services, React frontends, data models and infra. A React Node pairing is our default shape - a React Node frontend on a NestJS Developer backend, with a nextjs developer on SEO-critical pages. We replace fragmented setups where a website developer, web developer and front end specialist were stitched together. Adjacent angles I present daily: full stack developer saas for B2B platforms, python full stack developer pairings for data and AI, full stack developer ai integrations, full stack developer react teams for SaaS dashboards, full stack developer shopify extensions, full stack web developer rebuilds of legacy SPAs, full stack ai saas developer engagements where LLM features must ship at production standard. Our SaaS Developer team helps founders ship multi-tenant SaaS and B2B platforms. A SaaS Developer engagement covers auth and RBAC, Stripe billing, observability, anti-abuse and event tracking the saas marketing team can use. The team has shipped a webflow developer saas pairing, a b2b saas booking system developer engagement, a ui ux designer saas pipeline, a saas explainer video flow in onboarding and a saas sales console wired into the backend. On the API side a dedicated API Developer track owns contracts and versioning. A REST API Developer designs the REST API Developer surface - resources, pagination, idempotency, webhooks - and the API Developer keeps SDKs and docs honest. A Backend Engineer owns the data layer; a second Backend Engineer covers queues and workers so the API never blocks on jobs. Cross-language coverage. A python developer track owns scraping, ETL and AI workflows. python nodejs migrations land here when teams consolidate dual stacks. flutter node.js and vue.js node.js setups join the core when mobile or admin SPAs need a reactive layer. A react developer pairing handles SaaS dashboards on the API. A wordpress developer or shopify developer hand-off covers CMS migrations. A mobile app developer pairing extends the SaaS into iOS and Android. Clients hire me when they need: - a Node.js Backend Developer team that owns architecture, APIs and scaling - a back end developer node.js bench for high-traffic SaaS - a Full Stack Developer team replacing 3 - 5 contractors with one coherent system - a SaaS Developer team fluent in multi-tenancy, auth, billing and RBAC - an API Developer and Backend Engineer pair for a clean, versioned REST API Developer surface - a full stack software developer practice with CEO-level discipline on roadmaps - a website developer hand-off backed by the team Recent work my team shipped: - Cybersecurity SaaS. Node.js, NestJS, PostgreSQL, Redis on GCP + Kubernetes. 170M+ req/week, 500 RPS peaks, 1M+ MAU. - Device Verification SaaS. Single backend powering web, Telegram bot and Developer API. 4K+ DAU, 1M+ checks, 80%+ via API. - Clinic Enterprise platform. React, Next.js, Laravel, Node.js, Redis, AWS. REST API, queues, RBAC, 1C and lab integrations. MVP in 4 months for 500 patients/day, 500K records. - E-commerce Data Pipeline SaaS. 50M+ products, per-partner parsers, dedup. Cloud cost cut ~9x at sub-second search across 300 - 500K DAU. - Multi-currency Voting SaaS. Wallets, Stripe top-ups, real-time vote locking over WebSockets. 2M+ users in 10 countries, $2.5M+ revenue. Reliable SaaS comes from deliberate design - that's what my Node.js Backend Developer, Full Stack Developer and SaaS Developer team focuses on. Need a Node.js Backend Developer team, a Full Stack Developer team or a SaaS Developer partner that delivers on time and stays long-term - let's talk.

$87M in client revenue. 150+ projects shipped. Top 1% on Upwork. Not a pitch. Just receipts. I build web apps that actually work at scale. The kind that handle a million users without breaking a sweat. Django backends, React and Next.js frontends, and lately, a lot of AI integration work with LLMs and ChatGPT APIs. Here's what I bring to the table: ▸ Full-stack development (Django, Python, React, Next.js, MERN) ▸ AI and LLM integration (OpenAI, RAG systems, custom chatbots) ▸ SaaS architecture built for growth ▸ REST APIs and microservices that don't fall apart 73% of my clients come back for more work. Some have been with me for years. I think that says more than any badge. 10 years in, I've learned what separates good projects from disasters. Clear communication. No surprises. Shipping on time. Treating your business like my own. If you're building something serious and need someone who can lead the technical side, let's talk. Send me a message with your project details.

Full-Stack Developer Who Builds Products, Not Just Features Python • MERN • FastAPI Not every developer thinks beyond code. I do. I design and build scalable, production-ready web applications that don’t break when your users grow. Whether it’s a SaaS platform, a high-performance API, or a full product from scratch — I focus on making it fast, clean, and built to last. 💡 What Makes Me Different? Instead of just stacking technologies, I focus on how everything works together: ◆ Clean backend architecture that scales ◆ Frontends that feel fast and intuitive ◆ APIs that are reliable and easy to extend ◆ Code that another developer can actually read 🛠 Tech Stack I Work With Backend Power → Python (Django, FastAPI) → Node.js / Express (MERN) Frontend Experience → React.js (modern, responsive apps) → State management (Redux / Context) → Real-time & API-driven interfaces Database & Systems → PostgreSQL / MongoDB → Scalable schema design → Performance optimization & caching ⚙️ What I Can Help You Build ✔ SaaS Platforms (multi-tenant, scalable) ✔ Custom Web Applications ✔ REST APIs & Microservices ✔ Admin Panels & Dashboards ✔ MVPs for Startups ✔ System Refactoring & Optimization 🧠 How I Approach Projects I don’t jump straight into coding. I think in terms of: → Scalability (Will this handle growth?) → Maintainability (Can this be extended later?) → Performance (Will it stay fast under load?) That’s how you avoid rebuilding everything in 6 months. 🤝 Why Clients Stick With Me ✔ I communicate clearly (no ghosting, no confusion) ✔ I meet deadlines without sacrificing quality ✔ I solve problems, not just complete tasks ✔ I build with long-term vision, not quick hacks 👉 If you need a developer who actually understands product thinking — not just code — let’s talk.
