Hire the Best Engineering Freelancers
in Ukraine

FYI 01: I'm currently based in the European Union and can easily receive your devices, prototypes, or components for 3D scanning and reverse engineering to support further design improvements. Alternatively, as a result of my design services, I can send you 3D-printed and assembled prototypes. FYI 02: I’m planning to expand the scope of services I provide. In addition to design and development, I’ll soon be offering manufacturing support as well. Initially, this will include prototyping and small-batch production through a trusted manufacturing base in China. Later on, it will also cover refinement and support for full-scale serial production. This service is planned to launch around September-November, during my direct presence in China. I'm senior mechanical design engineer with multidisciplinary knowledge base. I've had the chance to gain my knowledge working at automotive (6 years) and aerospace (7 years) industry companies with complete manufacturing cycles. It helps me to view the product development process through the lens of the DFM (DFMA) and use the best development practices. Huge manufacturing background is always at my service and is one of my strengths. The second important strength is Solidworks CAD/CAM/CAE software's deep knowledge, including SW Add-Ins of other vendors. In addition, I develop the software applications for engineering purposes using C# .NET and do CAD automation using the full range of the capabilities from the equation and design tables to VB SW macro and SolidWorks API using C# language. ⇨ Product design workflow: Most likely and recommended to our typical workflow would be iterative with a mutual brief discussion. The main idea of this approach is to make the process of product designing more cost-effective, that means don't do extra work before no mutual agreement is reached. The typical stages are: General Concept & Layouting - First Prototype - MVP - Detailed Assemble - 2D drawings, GD&T - First Manufactured Prototype - Mass Production. Between all the stages can be minor adjustments to make the product more viable. ⇨ DFM, DFMA approach The important thing that I want to highlight is if any part has been modeled by me, be sure, it always means at least two things: - material type of the part is known - part manufacturing method is also known if the parts have been assembled, be sure, it means that assembly sequence is known as well another details as: fastening methods, possible friction pairs, dimension stack and gaps, surface roughness, surface treatments, etc. That'swhy, I'm ready to provide FULL SERVICE for the client projects from idea, first concept and MVP to first workable prototype manufactured using low series production methods and even up to their serial production if necessary. ⇨ SolidWorks CAD Automation and Parametric Modeling CAD automation can significantly improve the efficiency of development by eliminating an employee from repetitive tasks. Most often the 3D modeling requires automation for 3D model/assembly flexible rebuild into different configurations with different dimensions and geometry. Very often, such automation can be implemented by using standard SolidWorks tools like global variables, equations, and excel spreadsheets design tables without any programming languages. In cases of more complex CAD automation SolidWorks provides open application programmable interface (API or SolidWorks API) that allows software developers to make direct calls from another standalone app or built-in Solidworks Add-INs to SolidWorks core functionality using such programming languages as C# and not only. I'm not a professional software developer in usual meaning, I'm more mechanical engineer than software engineer, but I'm growing in this direction and have deep understanding of the SolidWorks software. I have already developed several software apps and modules for engineering purposes. I use C# .NET and WPF for these goals and I can help You with CAD automation tasks. ━━━ ○ For more details related to Industrial Design and Productization, see my Mechanical Engineer profile. ○ For more details related to CAD Automation or engineering application software development, see my Desktop Software Development profile. ━━━━━━━━━ 📗 I'm always open to job offer and ready to help you to turn your ideas into the real products. .

Hi, I'm Vlad 👋 Senior AI Engineer, 6+ years in IT. I ship AI features into B2B SaaS products and engineer them to survive production. For 2 years I was on the core team at Sellify AI, a vertical SaaS that sells outcome-priced AI sales agents to the US pest-control industry. What the system I helped build did for customers (public case studies): → Ninefold: $620k in new sales and 1,100 new accounts → HomeTeam, one of the largest pest-control operators in the US: over $1M in new revenue in a single month → Enviroguard: the AI agent sold 769 accounts in a year, roughly twice what the top human rep sold → Some features I worked on were so technically complex that several Sellify competitors couldn't figure out how to copy them. They updated their landing pages for the hype, but those features are still "coming soon" at the time of writing this. Those same features closed multi-six-figure clients. → Also built the integration with a complicated legacy pest-control CRM that became Sellify's moat and unlocked a major client Since then I've been the contract Senior AI Engineer for a recruitment-AI SaaS (1+ year, working directly with the founder): → Shipped a job-monitoring agent that's now live across several recruitment agencies. It watches job portals, filters per recruiter, and reaches recruiters over WhatsApp with human-in-the-loop approval flows → Built the e2e evals system (running in CI) so the client's internal dev team, with zero prior AI experience, maintains and extends everything without needing me → Also shipped a Meta ads agent: full campaigns from a vacancy description, generated creatives, competitor research through the Ad Library One of my clients Ove Andre Remme hired a freelancer with 20+ five-star reviews before me. Two weeks later he got a custom GPT that didn't do the job. I rebuilt it, and his verdict on the output quality was "perfect" (testimonial on my profile). Why this matters to you: the demo is the easy 20%. What I ship includes the other 80% - an eval suite in CI so regressions get caught before your customers see them, staged rollout where write-access is earned and anything touching money keeps a human approval step, cost engineering for scale, also docs and training so YOUR team owns it after I leave. Top Rated Plus (top 3% on Upwork) · 5.0 · 100% Job Success. If you're a SaaS founder with an AI feature on the roadmap, or a stalled attempt, message me. First step is a scoping conversation where I map architecture, cost at your scale, and timeline for your specific product. Tools I frequently use: • AI: Claude API, OpenAI API, Gemini, LLM-as-judge guardrails, prompt caching & cost optimization, AI agents & multi-agent systems, RAG, evals/CI for LLM systems, LangChain, structured outputs, function/tool calling • Integrations: Salesforce, HubSpot, legacy CRM integrations, WhatsApp (Twilio/Meta), Meta Ads API & Ad Library, Calendly, Shopify, WordPress/WooCommerce, Stripe, REST/webhooks/OAuth • Engineering: Python, TypeScript/Node.js, Java, React/Angular, PostgreSQL, Docker, microservices, GitHub Actions CI/CD, monolith→microservices refactoring • Product: agentic architecture design, human-in-the-loop workflows, cost/latency modeling, staged rollouts, documentation & team training
