Most people who hire me have a person doing something a script should be doing for them. Pulling the same data off websites every morning. Retyping invoices into a spreadsheet. Copying leads from one tool into another because the two won't talk to each other. Running the same report by hand for the hundredth time. If that's eating your week, that's exactly the work I take off your plate. I've spent the last 8 years building scrapers, automations, and lately AI agents that quietly handle this stuff so your team doesn't have to. Most of what I do falls into a few buckets: - Web scraping - grabbing data from sites, even messy or protected ones, cleaning it up, and dropping it wherever you need it, on a schedule if you want - Connecting your tools - getting Airtable, Make, n8n, Salesforce, Netsuite and Slack to work together so you stop copy-pasting between them - Pulling data out of documents - invoices, PDFs and scans turned into clean CSVs your accounting or system can actually use - AI agents and chatbots - the kind that read information, decide, and act, not the kind that only look good in a demo - Full web apps and fixes - for when you've outgrown the no-code tools or just need something built properly The part I care about most is what happens after I hand it over. I build in error handling so nothing fails quietly, and I write up how it works so your team isn't stuck without me. One client's server went down with an angry customer waiting on them. I stayed up through the night and got them back online. That's the kind of thing I want you to be able to count on. I'm Top Rated with a 100% job success score, so hiring me isn't a gamble. Tell me the thing you're tired of doing by hand. I'll tell you straight if I can automate it and roughly how long it'll take.

I help clients build and improve modern web products with strong backend logic, real-time features, and practical product thinking. My core stack is Next.js, Node.js/NestJS, PostgreSQL, MongoDB, Redis, and media/content workflows. 🚀 In my recent work, I helped modernize a multi-site content platform by replacing fragmented legacy workflows with a centralized system for publishing, media processing, support operations, and internal content management. I worked directly with stakeholders, clarified requirements, shaped implementation, and delivered critical parts myself, including media pipelines and a large MySQL-to-MongoDB migration. That migration involved 2M+ records across content, media, favorites, ratings, and related entities. I used deterministic ID mapping, relation maps, and streaming ETL flows to make the migration safer and re-runnable. I also optimized media delivery, including reducing one preview-video flow from about 25 MB to ~1.5 MB. ⚙️ In another project, I helped adapt and stabilize a purchased codebase for a subscription-based platform with PPV, paid chat, media workflows, and restricted-content access logic. A major part of my contribution was refactoring outdated patterns and implementing real-time permission logic tied to subscriptions and paid content. 💬 I also work well on marketplace-style and service-platform products where the core value comes from clean backend workflows and reliable user flows — for example: user roles, profiles, listings, applications, status management, dashboards, matching logic, and operational admin features.👷 I use modern AI tools to speed up delivery and improve product workflows. I use Codex, ChatGPT, and Gemini for prototyping, boilerplate generation, requirement clarification, and implementation exploration. I can also help integrate AI-powered workflows into products when there is a clear business use case. 🧠 I’m also expanding deeply into AI-assisted systems, particularly agentic RAG workflows and multi-step model orchestration for internal automation. In real use cases, I’ve already improved poor generation quality by redesigning embedding strategy, structuring source data more effectively, introducing specialized roles in the generation pipeline, and optimizing system prompts. My focus is on building AI workflows that are not only impressive in demos, but actually reliable and useful in production-like scenarios. Strong fit for: - Full-stack web applications - Backend-heavy product features - Real-time systems - Migrations and refactoring - Media/content workflows - AI-assisted product workflows If you need someone who can quickly understand a system, make solid technical decisions, and move delivery forward without unnecessary drama, I’m a strong fit. ✅
