You need someone who can own the AI/LLM layer of a product, not just call an API and hope it holds up in production. I work across three areas: LLM integration and AI system architecture, full-stack development (Python/Django and Node/Express backends, React/Next.js frontends), and technical consulting for teams that need a second set of eyes on an existing codebase. Recent scope: → Led the AI engineering function on a 2-year engagement, building agent-based systems with multi-model routing (Gemini, Claude, DeepSeek) for cost and capability trade-offs, vector + graph-based knowledge retrieval, and zero-downtime deployment pipelines. → Architected the backend and AI features for an enterprise education platform (Django, Next.js, PostgreSQL with vector search) built the systems behind student performance tracking and behavioral analytics. → Partner and core architect on an e-commerce SaaS platform (Vite, Express, Redis, RabbitMQ) handling multi-service coordination and graph-based knowledge retrieval. I design for the decisions that are expensive to get wrong: model selection and fallback logic, multi-tenant data isolation, retrieval architecture, deployment strategy. I write code that the next engineer can read without me in the room. Background: B.Sc. Computer Science (Istanbul Aydin University), TensorFlow Developer Certificate, IBM Data Science, AWS Solutions Architect, OWASP Secure Coding. If your project involves LLM integration, agent systems, or an architecture decision you're not sure about message me with specifics and I'll tell you directly whether I'm the right fit.

I build code-first Python data systems that turn messy, scattered, or large datasets into clean, reliable, and usable workflows. ⭐ I am a Top Rated freelancer with 100% Job Success, several thousand dollars earned, and hands-on experience across data engineering, ETL pipelines, API integrations, data processing, backend development, automation, databases, and AI-ready datasets. My work usually involves: 🔹 Collecting, cleaning, transforming, and structuring data from files, APIs, databases, and external sources 🔹 Building reliable Python pipelines for repeatable data processing, exports, reporting, and workflow automation 🔹 Designing database-backed workflows for storing, querying, organizing, and exporting structured data 🔹 Preparing structured datasets and knowledge bases for analytics, machine learning, NLP, or LLM/RAG systems 🔹 Creating custom backend tools, data workflows, and lightweight dashboards when the project needs more than a one-time script Recent projects included processing and structuring large volumes of data, cleaning and automating tens of thousands of data records, building data-driven systems, exporting datasets from databases, and developing AI-ready data workflows for real-world applications. I focus on clear communication, careful implementation, and practical systems that are easy to understand, maintain, and extend.

I build AI automation systems for US/UK small businesses, lead generation agents, customer support bots, and CRM workflows that actually run reliably. I build on dedicated infrastructure using Python and the OpenAI API, custom-built agents that run 24/7 on their own server, not fragile no-code stacks or shared SaaS tools that break the moment a vendor changes something. What I typically deliver: Lead generation and outreach agents (prospecting, qualifying, follow-up, CRM sync) Customer support automation (FAQs, order status, 24/7 coverage) CRM and workflow automation (Pipedrive, HubSpot, multi-step processes) I've spent 20+ years in IT before moving into automation, so systems are built to actually keep running, not just demo well. On Upwork I've completed 4 projects with a 5-star rating. Available to start within 48 hours, with an ongoing care plan if you want the system actively monitored and maintained.

www,celalettintoprak,com I design real products that get manufactured - not just 3D models. Manufacturing-ready CAD, prototyping, and Design for Manufacturing (DFM)-driven product development for industrial and consumer products. I’m an Engineer and Industrial Product Designer focused on manufacturing-driven product development. My background spans automotive, industrial, and consumer products, where I’ve worked as a Product Developer, Designer, and Technical Lead in production-oriented environments. I don’t approach projects as isolated design tasks. I approach them as systems that must survive prototyping, manufacturing, assembly, cost pressure, and real-world use. 📐 What You Can Expect Working With Me: - Clear, structured CAD suitable for iteration and production - Design decisions informed by manufacturing reality - Practical communication with engineers, suppliers, and manufacturers - Honest feasibility feedback (go / no-go when needed) - Designs meant to be tested, not just rendered 📐 Core Capabilities: - 3D CAD modeling (Siemens NX) - 2D technical drawings (AutoCAD Professional) - CNC, laser cutting, and sheet metal preparation - Injection molding–ready part design - Fixture, bracket, and assembly design - BOM creation and production planning support - Reverse engineering and scan-based modeling 📐 Injection Mold & Manufacturing Experience I have hands-on experience designing plastic injection molds and mold-ready parts, including projects for automotive and food-related products. ⚙️ I’m familiar with: - Injection molding–ready design, Core / cavity logic - Draft angles & wall thickness optimization - Parting lines and shut-off surfaces - Shrinkage and material behavior - Gate concepts (hot runner, valve gate) - Collaboration with mold makers and CNC shops - Design for Assembly (DFA), production validation - Engineering-driven product development - Long-term product roadmap support My focus is always on tool longevity, cycle time, surface quality, and cost efficiency. 📏 Typical Projects I Work On: - Automotive accessories and aftermarket products - Mechanically complex plastic or metal parts - Prototyping-heavy product development - Production validation before tooling - Redesigns for cost reduction or manufacturability - CAD clean-up and production conversion 📌 Primary CAD Tool: Siemens NX, AutoCAD and Geomagic Design X I work primarily in Siemens NX, which is widely used in high-end automotive and industrial manufacturing. I can deliver clean, fully editable STEP / STL / Parasolid files, and I regularly convert and work with SolidWorks, Fusion 360, Rhino, SketchUp, and scan-based data. If you use SolidWorks or another CAD system, this is not a limitation — deliverables are always production-ready and compatible. 📌 If you need more than a modeler—someone who understands how products are actually built and scaled—I can support your project from concept to production readiness.
