❇️ AI-Native Full-Stack Engineer & Solution Architect | 16+ Years | 100+ Global Projects I build production software the way modern engineering teams actually work now: AI-assisted from architecture through delivery. I use Claude Code daily to design, scaffold, and ship full-stack systems faster — and I build the AI itself into the products I deliver: RAG pipelines, LLM-powered agents, and AI-driven data extraction. Recent AI-native work: ⚡ Multi-tenant RAG chatbot SaaS — architected a production platform with semantic vector search (PostgreSQL + pgvector), OpenAI embeddings, and an embeddable website widget, with tenant-isolated knowledge ingestion for enterprise customer support. ⚡ AI-powered market analytics platform — led a 9-person team building a brand-analytics tool (React/TypeScript + Python FastAPI + MongoDB/ClickHouse) with an LLM agent that answers analyst questions directly against enriched brand data. Built largely via AI-assisted ("vibe coding") workflows in Claude Code. ⚡ AI-based universal web scraper — built a prompt-driven extraction engine (AgenQL + Playwright) that scrapes structured product/review data from almost any e-commerce site without site-specific selectors. Beyond these, I bring 16+ years of full-stack and cloud architecture across React/Next.js/Angular frontends, Node.js/Java/Python backends, and AWS/Azure/ GCP infrastructure — so AI features I build sit on top of systems that are actually production-ready, not prototypes. 🔷 Core AI/LLM Expertise ✔️ Claude Code — AI-assisted architecture, scaffolding, and full-stack delivery ✔️ RAG systems — vector search (pgvector), embeddings, semantic retrieval ✔️ LLM integration — OpenAI GPT-4o/4.1, prompt-driven agents and data pipelines ✔️ AI-powered automation — prompt-based extraction, AI agents for analytics 🔷 Full-Stack & Architecture ✔️ Frontend: React.js, Next.js, Angular, TypeScript, Tailwind, MUI, Bootstrap ✔️ Backend: Node.js (Express, LoopBack), Java (Spring), Python (Django, FastAPI) ✔️ APIs: REST, GraphQL (Apollo) ✔️ Databases: PostgreSQL (+pgvector), MongoDB, Oracle, MySQL, SQL Server, Elasticsearch, ClickHouse, DynamoDB 🔷 Cloud & DevOps ✔️ AWS (Lambda, API Gateway, S3, Cognito, Kinesis, Athena, ECS) ✔️ CI/CD: GitHub Actions, CodePipeline/CodeBuild/CodeDeploy ✔️ Google Cloud, Microsoft Azure (Pipelines, Boards, AD SSO) 🔷 Geospatial & Data Visualization ✔️ CesiumJS, ArcGIS, OpenLayers, Google Maps, Mapbox ✔️ Power BI, Highcharts, Recharts, Chart.js, Jasper, BIRT I partner with teams that want AI features that actually ship — not demos — backed by architecture that scales.

I have 10+ years of experience building end-to-end dashboards, marketing analytics platforms, and data warehouses for organizations ranging from startups to publicly traded enterprises like Wayfair, as well as government organizations such as the Commonwealth of Massachusetts. I have held senior roles such as Head of Data and Enterprise Data Architect, and my background in software engineering allows me to build analytics systems that go far beyond basic dashboards, with clean data pipelines, reliable attribution, and automated reporting. I can help you consolidate data from multiple platforms (ad networks, analytics tools, e-commerce systems, CRMs) into a single, reliable source of truth. Whether you need cross-channel attribution, blended ROAS and CAC calculations, white-labeled client reporting, or a scalable data warehouse foundation, I can build and maintain the infrastructure that makes clean reporting automatic instead of a weekly time sink. Here, you can check out a few of my case studies: I helped Wayfair's Marketing Engineering team develop a comprehensive cross-channel attribution model that unified data from paid search, display, email, social media, and content marketing. The project involved implementing server-side tracking, building ML-powered attribution models, and creating dashboards that visualized the complete customer journey. The result was a 16% increase in ROAS and multiple 8-figures in additional revenue through optimized ad spend and improved customer targeting. I helped Kum&Go, a retail company with 430 stores and nearly 500K loyalty subscribers, implement RFM segmentation using machine learning. The project involved collecting and normalizing customer data, building K-means clustering models, and creating actionable customer segments for targeted marketing campaigns. The results included an 18% increase in email open rates and click-through rates, along with a 16% increase in customer lifetime value. I also support marketing agencies with white-labeled dashboard solutions that pull live data from their clients' ad accounts, eliminating the manual spreadsheet exports and screenshot reports that consume hours every week. My approach saves their respective teams 5-10 hours every week on reporting, and ensures the numbers are always consistent and trustworthy. I can extract and normalize data from virtually any source, including ad platforms, e-commerce systems, email marketing tools, CRMs and more. When it comes to building dashboards, I have extensive experience with the following technologies: Analytics and CRM: GA4, HubSpot, Klaviyo, Salesforce, ActiveCampaign Data Warehouses: BigQuery, Snowflake, Amazon Redshift, PostgreSQL, ClickHouse Data Visualization: Power BI, Looker Studio, Tableau, Data Studio, Metabase, Superset Thanks for taking the time to read this. If you think we might be a good fit, feel free to send me a message here on Upwork. Looking forward to connecting with you!

If you need a full stack developer and engineer who can deliver without rework, I can help. ✅ 6,000+ hours worked on real client projects ✅ 15+ MVPs delivered, from idea to working product, ready to scale ✅ 100% Job Success Score ✅ Top 3% of talent on Upwork Beyond building from the ground up, I specialize in jumping into existing codebases to stabilize and scale them. Whether you are dealing with technical debt, legacy systems, or performance bottlenecks, I provide deep-dive audits, refactoring, and feature optimization to ensure your current product is production-ready and built to handle increasing user loads. I’m a senior full stack engineer working with React, Node.js, Python, and PHP. In my work, I focus on building real products end-to-end, from idea to production, with full ownership and predictable delivery. I work primarily as a full stack engineer specializing in React and Node, building modern web applications using React, Next.js, and Node.js. On the backend, I also work as a full stack engineer with Python and PHP, choosing the right stack based on the product and scaling needs. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Skills & Services ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ Backend: Node.js, Python, PHP, Laravel, Express ▸ Frontend: React, Next.js, JavaScript ▸ Databases: PostgreSQL, MySQL, MongoDB ▸ APIs: REST APIs, third-party integrations ▸ DevOps: AWS, Docker, CI/CD As a full stack engineer (Node.js/Python), I build robust APIs, business logic, and complex integrations. As a full stack engineer (React/Next.js), I build fast, clean, and scalable interfaces. I often lead full stack engineer React Node projects, connecting frontend and backend into a single reliable system. I also take on PHP projects when stability and speed of delivery are critical. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ How I Work as a Full Stack Engineer ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ As an experienced full stack developer, I focus on: – Clean and scalable architecture – Fast frontend with React and Next.js – Stable backend with Node.js, Python, or PHP – Production-ready delivery I can join as a full stack engineer or take a broader role with total ownership over architecture and execution. Beyond standard engineering, I bring the comprehensive mindset of a senior web developer to modernizing legacy systems. For instance, if your platform was originally built by a WordPress developer and is now struggling to scale, I specialize in migrating those monolithic systems into custom, high-performance architectures. If your business has outgrown what a standard WordPress developer can provide, I can rebuild your platform from scratch. As a React developer, I transform outdated interfaces into blazing-fast web apps. Additionally, while I am not a native mobile app developer, I regularly collaborate with your mobile app developer team by building the robust backend infrastructure and optimized REST/GraphQL APIs they need. Every professional web developer knows that a great frontend depends on a solid backend, so I ensure that your mobile app developer gets seamless, well-documented endpoints, while I focus on the web ecosystem as a dedicated React developer. Ultimately, whether you are transitioning away from a legacy WordPress developer setup, looking for a web developer to build enterprise-grade systems, or need a React developer who knows how to support a mobile app developer, I deliver clean, production-ready code. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Experience ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ SaaS products ▸ Internal tools and dashboards ▸ Travel & Logistic platforms ▸ Fintech platforms ▸ E-commerce systems As a full stack developer React Node, I deliver complete products that are ready for real users and real load. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ If you are looking for a full stack engineer who can take ownership and ship, feel free to reach out.
