I build AI automation that actually ships and keeps running — n8n & Make workflows, AI agents, and RAG chatbots — on top of 10+ years of Python automation, web scraping, and data engineering. Top Rated Plus · 100% Job Success · 67 jobs · 4,000+ hours. Most freelancers can drag-and-drop a no-code flow. Almost none can get the data in. Pulling it from sites that don't want to give it up, cleaning it, and feeding it reliably into your systems — that's the hard half, and it's what I've done at scale for a decade. It's also why my automations don't break in week two. What I can build for you: ▸ Web scraping & browser automation — large-scale extraction from difficult sources with Python, Scrapy, Selenium, and Playwright: proxies, anti-bot handling, login flows, and browser agents that click, fill, and navigate like a person. The data layer most AI projects fall over on. ▸ AI automation & agents — n8n / Make workflows with AI steps that classify, extract, summarize, and decide; multi-step AI agents that use tools and take action (Claude, GPT, Gemini). ▸ RAG chatbots — assistants that answer from your own documents and data, with every answer grounded in a cited source (PostgreSQL/pgvector, embeddings, hybrid search). ▸ Data pipelines — ETL, enrichment, monitoring, and scheduled jobs that keep running unattended, with error handling and alerting built in. ▸ Integrations — HubSpot, GoHighLevel, Airtable, Google Workspace, Slack, Telegram/WhatsApp, REST APIs, and webhooks. Why the scraping background matters for AI work: an AI agent is only as good as what you feed it. Garbage input, confident nonsense out. I handle acquisition, cleaning, and delivery — so the AI layer on top has something real to reason about. How I work: ▸ Consult first, then automate — we fix the real bottleneck, not just the obvious one. ▸ Every build ships with source code, documentation, and error handling, so it survives the handoff. ▸ Clear, proactive communication on US-friendly hours; honest about scope and cost up front. 10+ years in software, a Master's in Cyber Security, and a track record clients describe as creative, thorough, and reliable. If a workflow is eating your team's hours — or you have an "AI setup" that sounds impressive but doesn't solve anything — message me with what's slowing you down, and I'll tell you exactly how I'd automate it.

You need software that solves a real problem, built right the first time, by people who understand your business and not just your stack. I'm Orest, founder of SoftDoes. We're a U.S.-based custom software firm working with: • Non-technical founders with a vision • Technical leaders who need help but not additional headcount • Business operators solving operational complexity Our team has delivered across healthcare, fintech, construction, legal, real estate, and regulated industries where compliance-readiness is required and getting it wrong isn't an option. Our clients tend to show up in one of three situations: they have a product vision and need someone to build it, they have internal engineering that's stretched too thin, or they have operational complexity that off-the-shelf software simply can't fix. We've handled all three. What we deliver: • Custom software and SaaS platforms built for scale • AI implementation and automation built into real workflows • Web and mobile applications • Cloud infrastructure on AWS, GCP, and Azure • Full-stack development across React, Next.js, Node.js, and Python What clients tell us, consistently: we listened, we delivered what we said we would, and they didn't have to babysit us to get there. A healthcare founder went from concept to a live, compliant product in under six weeks. A construction company replaced five fragmented tools with one custom operations platform. A fintech team cut onboarding time in half with an AI-assisted workflow we built in a single sprint. We work best with companies that are big enough to need real software and clear-eyed enough to know that building it wrong the first time costs more than doing it right.
