I build and stabilize AI automation, agents, and full stack SaaS products that need to work reliably in production, not just in demos. I’ve shipped and scaled systems for founders from Y Combinator, Founders Factory, FutureLabs, and Republic of Work. Founders I’ve built with have gone on to raise €2M+, and my AWS/serverless work ranks in the top 0.2% for DevOps. A few results: ⚡ Multi-tenant SaaS with 28% faster integrations ⚡ Serverless system running under 200ms latency at 10K+ users ⚡ AI RAG system improving support efficiency by 45% ⚡ Next.js migration reducing hosting costs by 15% ⚡ SaaS MVPs shipped to production, with founders raising after launch A lot of products today get built quickly with Cursor, Lovable, Bolt, Claude Code, or an early freelance team. Then real users arrive. That’s when the problems show up: messy code, fragile backends, AI features that worked in the demo but fail in production, scaling bottlenecks, unreliable automations, and rising AWS costs. I help turn that into a production-ready system with clean architecture, a solid backend, reliable AI behavior, and room to scale. I also build new products properly from idea to MVP to production. What I can help with: * AI agents, chatbots, and AI voice agents * Workflow automation and business process automation using n8n, Make, Zapier, and APIs * Production RAG, LLM, and knowledge-based systems * Full-stack SaaS development with Next.js, React, Node.js, TypeScript, JavaScript, and Python * Backend systems, REST APIs, third-party integrations, and multi-tenant architecture * PostgreSQL, Supabase, Stripe, AWS, serverless, performance, and cost optimization * Stabilizing fragile or AI-built MVPs before they become technical debt How I work: We can start small. Send me your app URL, repo, or brief with a short note on the problem. I’ll review the likely bottlenecks, scaling risks, reliability issues, and what I would fix first before you commit to anything bigger. From there, I can take technical ownership of the build: architecture, backend, integrations, AI systems, delivery, and the parts that usually stall. I work best with: * Funded startups starting with or moving beyond MVP * SaaS teams hitting scaling, reliability, or cost issues * Founders who want a senior engineer to take ownership, not just ship tickets I’m probably not the right fit if you’re looking for the cheapest possible build. I’m a fit when the product matters, users depend on it, and it has to work. Tech I work with often: Python, JavaScript, TypeScript, React, Next.js, Node.js, AWS, Supabase, PostgreSQL, Stripe, serverless, OpenAI, Claude, Gemini, RAG, LangChain, AI agents, n8n, Make, Zapier, automation, and APIs. If your product was built fast and now needs to work properly, or you want it built right from the start, send me the repo, app, or brief, and I’ll tell you what I’d fix first.

I've spent 7+ years building Python systems as a developer before going full-time on Upwork last year. I focus on two kinds of work: turning unstructured data into something an LLM can actually reason over, or extracting data from the web at scale. What I build: - RAG pipelines that make docs, PDFs, and internal knowledge searchable through a chat interface - AI agents that chain LLM calls with tool use to automate tasks that used to need a human in the loop - Large-scale scrapers for targets behind Cloudflare, anti-bot fingerprinting, or heavy JS rendering - ETL pipelines that clean extracted data into structured JSON or SQL for downstream use - FastAPI backends and dashboards for AI and data workflows Recent projects: - AI platform that converts any website into a production-ready HubSpot theme — cut setup from 3-4 days to under an hour, live in production for a HubSpot agency - Parts aggregation system pulling 50M+ records from 3 supplier sites, with a monitoring dashboard for extraction health - Court records lead system for a legal advocacy firm — extracts filings from 3 US court websites into a searchable dashboard used daily Core stack: - Languages: Python, SQL - AI/LLM: LangChain, OpenAI API, Anthropic API, Llama, Tensorflow, Pytorch - Vector DBs: Pinecone, Qdrant, pgvector - Scraping: Playwright, Scrapy, BeautifulSoup, Selenium - Backend: FastAPI, PostgreSQL, Celery, Redis, Flask, Django - Infrastructure: Docker, AWS - Deployments: Runpod, Heroku, any Windows/Ubuntu Servers How I work: - I flag spec problems early instead of building the wrong thing - I ship code that runs in your environment, not just on my machine - I stay reachable after delivery so you can actually use what I built If you're considering me, send a short message describing the problem you want solved. I'll reply with whether I think I can help and how I'd approach it.

I’m a Full Stack Developer, Python Developer, and MVP & SaaS Backend Developer focused on building production-ready software that holds up under real-world usage. My work sits at the intersection of software developer, web developer, and SaaS platform builder, with a strong backend-first mindset and deep attention to scalability, performance, and long-term maintainability. As a Full Stack Developer, I take ownership of systems end-to-end, pairing robust backend architecture with clean, responsive user interfaces. My full-stack approach allows me to bridge the gap between front-end presentation and deep data layers, ensuring I can own both frontend and backend workflows in a single, coherent system rather than splitting focus across siloed roles. As a Python Developer, I use Python's scalable ecosystem to build highly performant, predictable, and maintainable backend systems. Utilizing frameworks like Django, I design clean database architectures, complex data models, and secure user management flows that serve as the backbone for heavy-traffic applications. My deep familiarity with Python allows me to write clean, idiomatic code optimized for speed, reliability, and seamless data processing. As an MVP & SaaS Backend Developer, I help companies rapidly move from concept to validation by designing, building, and scaling SaaS products, internal tools, and API-driven web applications intended for long-term growth. My experience allows me to think beyond immediate features and focus heavily on cloud architecture, database optimization, and operational stability on platforms like GCP from day one. Many of the platforms I build support internal teams, budget planning tools, and multi-role workflows where permissions, data integrity, and strict business rules are critical. In my day-to-day work, I design and implement backend services, RESTful APIs, and custom administrative tools that power complex web systems. I specialize in building scalable architectures, background jobs, and asynchronous workflows that perform reliably in high-concurrency production environments, ensuring that rapid MVP development never compromises future stability. As a Full Stack Developer, I ensure these backend systems integrate cleanly with user-facing dashboards and third-party APIs. This end-to-end technical ownership is a key reason clients bring me in to architect their MVPs, trusting me to build an agile product that satisfies early adopters while maintaining a rock-solid foundation for enterprise scaling. A significant portion of my work involves building internal platforms, dashboards, and automated systems that integrate external services. In these projects, I design clean data pipelines, event tracking, and core backend logic that supports business growth, reporting, and deep analytics insights. When projects require advanced automation or AI-powered functionality, I bring hands-on experience integrating intelligent workflows directly into the backend. While my primary role remains Full Stack Developer and Backend Developer, I regularly implement data processing pipelines and automated features inside SaaS platforms, delivering business automation that is reliable, observable, and cost-controlled. Clients typically work with me when they need: ➡️ a Full Stack Developer who can fully own both frontend and backend systems. ➡️ a Python Developer who understands deep database architecture and long-term scalability. ➡️ an MVP & SaaS Backend Developer experienced with launching real production systems on GCP. ➡️ Web applications with complex workflows, budget planning systems, and custom admin tools. ➡️ Clean API-driven architectures, custom RESTful APIs, and third-party integrations. ➡️ MVPs engineered to realistically evolve into heavily trafficked, long-term SaaS products. Core Technical Focus: ➡️ Backend & Frameworks: Python, Django, and scalable web systems. ➡️ APIs & Automation: RESTful APIs, asynchronous background jobs, and automated workflows. ➡️ Data & Infrastructure: Robust database architecture, optimization, and GCP cloud deployment. ➡️ Security & Logic: Authentication, multi-role permissions, dashboards, and data pipelines. ➡️ AI Integration: AI-enabled backend features and intelligent data processing pipelines. I regularly work on MVP builds and early-stage products as a Full Stack Developer, with a strong focus on solid backend foundations, rapid but reliable development paths, and avoiding fragile, short-lived prototypes. Based on project scope and timing, I work hands-on across the entire stack, ensures your product transitions smoothly from an agile MVP to a mature SaaS platform. Long-term results come from technical reliability, clean data flows, and intentional system design. I focus on delivering software that businesses can confidently run, maintain, and scale to fuel their growth.
