I am a Business Systems Analyst with extensive experience analyzing business processes, structuring information, and developing practical solutions for real business environments. My work focuses on understanding how business processes actually operate, how information moves between people and systems, and where existing workflows can be improved without disrupting what already works. I analyze business logic, data structures, operational constraints, and real-world usage patterns to identify practical opportunities for process optimization, automation, and better information management. My experience combines business analysis with hands-on implementation. I have designed and improved business information systems, databases, workflows, and analytical tools supporting inventory management, accounting, logistics, finance, export/import operations, and internal document management. How I can help you: • Analyze and optimize business processes and operational workflows • Structure complex business information and data • Analyze, verify, and reconcile data across systems and sources • Design and improve business information systems • Identify opportunities for practical automation and process improvement • Develop data-driven solutions supporting daily business operations • Improve existing database systems I approach each project from the business process first and select the technical solution accordingly. The goal is not technology for its own sake, but a practical system that reflects how the business actually works.

I'm Gökhan — a software engineer with 12+ years of production experience, now focused on building AI systems that actually run in production, not demos. Most AI projects stall at the same point: the prompt looks great in a test, then breaks against real data, real users, and real infrastructure. I work on the other side of that line — retrieval that stays grounded, agents that fail predictably, and integrations that hold up under load. What I build: RAG and internal knowledge assistants (pgvector, embeddings, self-hosted or API models) AI agents and workflow automation (n8n, webhooks, CRM and third-party integrations) Voice AI agents (VAPI, Retell) with telephony, SMS, and CRM integration Custom GPT / OpenAI assistant workflows and chatbot logic Multi-tenant SaaS backends that host AI features (NestJS/TypeScript, .NET Core, PostgreSQL) Prompt architecture, evaluation, and cleanup for systems already in production Self-hosted LLM deployments where data can't leave the client's infrastructure Because I come from a backend engineering background, I don't hand over a prompt and stop there. I handle the data layer, the API design, the deployment, and the documentation — so what you get is a working tool your team can maintain, not a proof of concept. On Upwork I've earned $40K+ across 1,000+ hours and hold Top Rated Plus status, with a 100% focus on delivery and clear communication. I'm also the founder of Peakersoft, where we build sector-specific SaaS products — so I understand projects from the product side, not just the code. If your project needs more implementation bandwidth than a single freelancer, I can coordinate additional development support through Peakersoft. If you're looking for someone who can scope the AI workflow, build the system, and keep it grounded in something usable, let's talk.
