Prior to moving into a Freelance role, I've operated as Analyst Developer, Software Engineer and Project Manager while handling multiple international assignments that reached across Europe. I'm no stranger to hard work or complex tasks, and have the portfolio to back that up. I'm skilled and specialize in many aspects of Software Engineering, including (but not limited to): * .NET Technologies: * C# * Windows Form * WPF * ASP.NET Core * Angular * WCF * UWP * MsSql Server * Postgresql * Rest Services * ASP.NET Core * PMP (Project Management Professional) I'm strongly experienced in WPF and MVVM pattern, having handling a multitude of WPF projects in the recent past (which I'm happy to discuss with you as a means to establish my knowledge and expertise). Web apps with Net core backend and Angular frontend. More than anything though, my decade-and-a-half of experience and track record of high-level work in each position I've held is a testament to my professionalism, and I'd love to show you how that translates to your project needs. I believe in timeliness, constant quality checks, and an open, two-way line of communication. The best projects are built with a group effort between freelancer and client. If you're interested in my services, let me know! I'm available on Freelancer, and can be reached via the messenger or the 'Hire Me Now' button. I'll get back to your initial message as early as I can, and we can jump straight into an initial meet-and-greet/brainstorming session. Thank you for your time! 收起

My core focus is designing, building, and deploying AI-driven systems—from LLM-powered agents and voice assistants to data-aware automation pipelines that integrate seamlessly with production applications. I work extensively with large language models (LLMs), retrieval-augmented generation (RAG), vector databases, embeddings, tool-calling frameworks, and agent orchestration patterns to create systems that reason, act, and scale reliably. On the backend, I build high-performance APIs and services using FastAPI, Flask, Node.js, and Django, with strong experience in async architectures, background workers, and event-driven systems. I regularly work with PostgreSQL, MySQL, Redis, MongoDB, and Neo4j, and design robust data layers using SQLAlchemy, Prisma, and ORM/DAO patterns. For AI workloads, I integrate OpenAI, Anthropic, Ollama, ElevenLabs, and custom inference pipelines, alongside Qdrant, Pinecone, FAISS, and hybrid search setups. On the frontend, I build modern, scalable interfaces using React, Next.js, Vite, Tailwind CSS, and TypeScript, with a strong emphasis on UX for AI-powered tools (real-time streaming, agent state visualization, conversation flows, and admin dashboards). For mobile, I work with React Native and cross-platform architectures to bring AI features directly into user-facing apps. Automation is a major part of my work. I design end-to-end business automation systems using Make.com, n8n, webhooks, cron jobs, message queues, and direct API integrations. This includes automating CRM workflows, email systems, call routing, lead qualification, reporting, and data synchronization across platforms like Twilio, Slack, Google Sheets, Stripe, Shopify, and internal tools. I’m highly experienced in AI voice agents and real-time systems, integrating Twilio, speech-to-text (STT), text-to-speech (TTS), streaming APIs, and conversational state management to build production-ready voice and chat agents. I also work on computer-vision and multimodal pipelines, combining vision models, tracking, and sensor data for advanced use cases. From an infrastructure and MLOps perspective, I deploy and scale systems using Docker, Linux servers, cloud VPS, CI/CD pipelines, and GPU-accelerated environments. I care deeply about observability, logging, error handling, security, and cost optimization in AI systems. Above all, I love turning business problems into automated, intelligent systems—reducing operational friction, increasing efficiency, and building products where AI is not a feature, but a core capability. If you need AI agents, automation pipelines, or full-stack systems that actually work in production, that’s exactly what I build. 收起

I work closely with clients to understand their objectives, define priorities, and design clear, realistic roadmaps. In this role, I act as a strategic advisor and technical partner, ensuring that business decisions translate into robust and sustainable technical solutions. From a technical standpoint, I design end-to-end architectures covering infrastructure, security, identity, integrations, and automation. I have hands-on experience with Cisco ISE and Cisco Meraki, designing secure access models, authentication flows, and enterprise network integrations. I also bring strong DevOps and platform experience, including infrastructure design, deployment pipelines, and system reliability. While my primary role is architecture and consulting, I maintain a solid software engineering background, with hands-on experience in technologies such as Node.js, Laravel, and modern frontend frameworks. This allows me to validate architectural decisions, collaborate effectively with development teams, and ensure that solutions are technically sound and buildable. This hybrid approach reduces friction between strategy and execution, shortens delivery cycles, and delivers solutions that work in real environments not just on diagrams. 收起

I specialise in AI-driven software engineering using Python, JavaScript, and AWS, building everything from fast APIs to full end-to-end SaaS platforms. Front-end to back-end, I turn ideas into smooth digital experiences. SQL or NoSQL — I design and optimise databases that run clean and handle real load. APIs & automation — I build scalable REST services and workflow automation that keep products running smoothly. My approach is simple: engineer clean systems, automate the boring parts, and make everything feel seamless in the real world — from the UI to the database to the cloud. Over the past few years, I’ve been working hands-on with AI across practical, production-ready use cases: chatbots, trading bots, analytics tools, talking avatars, object detection, and image generation. My focus is always the same - making AI engine that actually get used, make sense, and deliver value to the product. Whether it’s Python microservices, JavaScript front-ends, AWS cloud architecture, or building a full SaaS system from scratch, I aim for clean engineering and a result that feels remarkable in the real world.
