I grew my own instagram page to 10,000 followers and 2.1 million views in 45 Days, running it on the automations I built for it. I build AI automation systems in n8n — lead generation, content repurposing, and AI agents Systems for agencies and founders who are losing hours every week to work a system should be doing. The longer, sit-down version (if you've got a minute): Most people selling "automation" have never had to make a system earn its keep. I've spent 12 years in marketing and now run my own automation-powered content operation, so every system I build gets judged the same way yours will be: did it actually produce something? ⚡ Systems I've built and run in production: ✅ Lead research & outreach engines — scrape a company, research it with GPT and Gemini, write a personalised first-touch email, log everything to a CRM, and run unattended on a schedule ✅ AI sales agents on WhatsApp with a built-in CRM — qualify inbound leads, answer questions, book the call, and update the opportunity record themselves ✅ Cold email infrastructure — domains, mailbox warm-up, deliverability monitoring and sequence automation across a nine-mailbox setup ✅ Competitor ad intelligence — pull a competitor's live ads daily, score them with GPT, deliver a weekly brief ✅ Content engines for LinkedIn and short-form video — mine reference posts, generate on-brand drafts, handle images, and publishing end to end ✅ AI voice receptionists that answer, qualify, and book straight into a calendar ✅ Customer support agents with RAG over your own documents, plus ticket routing and escalation ✅ Custom dashboards and internal tools in Next.js and Supabase, for when a spreadsheet or an Airtable base stops being enough 🔧 The unglamorous part, which is where most automations actually die: Tools: n8n, OpenAI / GPT-4o, Claude, Gemini, Apify, Supabase, Postgres, NocoDB, Airtable, Google Workspace, Slack, WhatsApp Business API, Twilio, Next.js, Python, JavaScript. How I usually work: a fixed-fee build, then a monthly retainer to run, monitor, and extend it. Send me the messy version of the process that's eating your week. Within 24 hours, I'll tell you honestly what can be automated, what can't, how I'd approach it, and what it would cost — even if the answer is that you don't need me. Looking forward to meeting you!

Create leverage. That is what I do. I build high-performance, secure, reliable software that helps founders and businesses launch and scale with confidence. Since 2010, I have helped founders and established companies turn ambitious ideas, messy workflows, and broken systems into serious software products. Obsession with quality, complete transparency, and no hand-holding - that is how I turn software from a development expense into a business asset. I am an excellent fit if: - You are a founder with a product idea and need more than “someone to code it.” I can help you refine the concept, define the right MVP, validate technical assumptions, choose the right architecture, build the first production-ready version, and support you after launch as the product grows. - You are an established business looking to build a new platform, automate operations, replace spreadsheets, improve workflows, modernize legacy software, scale an existing product, or rescue a bad build. I am especially valuable when the project is too important to gamble on cheap execution, unclear ownership, fragile architecture, or developers who only wait for task lists. I have spent 15+ years building software where failure is expensive, across product types, workflows, and industries including SaaS platforms, AI/RAG systems, internal tools, dashboards, CRM/ERP/POS systems, logistics platforms, marketplaces, real estate software, e-commerce, FinTech, EdTech, HealthTech, data analytics, travel, hospitality, and regulated sports betting The value of that experience is not just knowing different industries. It is knowing the patterns behind them: workflows, permissions, payments, reporting, integrations, data integrity, performance, edge cases, and the business logic that quietly decides whether a product becomes scalable or painful. I personally lead architecture, planning, communication, and delivery. When a project needs more capacity, I bring in my senior team to provide high-level technical ownership and reliable execution. Whether you are a non-technical founder, an operations-heavy business, or a technical team that needs senior delivery support, I will communicate at the right level: clear when needed, technical when useful, and always focused on decisions that move the project forward. I am based in Turkey and regularly work with US, UK, Canadian, European, and Australian clients. I work EST hours with reasonable PST overlap, so communication across time zones is smooth. Don’t settle for mediocre. In a world of ruthless competition, make me your unfair advantage. Send me a message today, and I will map our next steps.
