Senior Full-Stack Engineer / Software Architect with 15+ years of experience building, modernizing and maintaining production software for clients worldwide. With 36,000+ hours and 100+ projects completed on Upwork, I've worked across the full software development lifecycle — from requirements and architecture through implementation, testing, deployment and long-term maintenance. My core expertise is in the Microsoft/.NET ecosystem: • C# / ASP.NET Core / .NET 6–8 • REST APIs & API-first architectures • Entity Framework Core / SQL Server / PostgreSQL • Angular / TypeScript / React • Azure / AWS / CI/CD • Microservices, modular monoliths & distributed systems • RabbitMQ / Redis / MongoDB • Application modernization and legacy system migration I particularly enjoy taking ownership of complex or long-running projects where understanding the business domain is just as important as writing the code. I have extensive experience working independently with international teams, communicating directly with stakeholders, investigating production issues, improving existing architectures and delivering software that needs to work reliably in real-world environments. More recently, I've incorporated AI-assisted development into my workflow — using AI for requirements analysis, planning, implementation, testing, code reviews, documentation and refactoring, while maintaining engineering standards and carefully reviewing generated code. If you need a senior engineer who can do more than implement tickets — someone who can understand the bigger picture, make technical decisions and take ownership of delivery — I'd be happy to discuss your project. Outside of work, I enjoy spending time with my two kids and running. I've completed 40+ marathons, which has taught me a lot about consistency, patience and long-term goals. I'm always open to interesting projects and challenging technical problems. If you're looking for an experienced engineer who takes ownership and cares about delivering quality software, let's talk. **15+ years experience | 36,000+ Upwork hours | 100+ projects | 100% Job Success | Top Rated Plus**

Hi, I'm Alex 👋 I build automations that save companies time, reduce costs, and remove operational bottlenecks. ➡️ One automation reduced a logistics client's manual workload by 740 hours/month. ➡️ A custom LLM-based triage bot saved an insurer $110,000/year. ➡️ A robust RPA that helped a finance client tackle the daily challenge of managing debit card dispute and fraud chargeback cases, reducing manual effort effort from 2+ hours/day to under 10 minutes - a savings of over 40 hours/month (500+ hours/year). So, if you're looking for measurable impact, you're in the right place. ───────────────── A bit longer version for those who want to know me better (which I'm looking forward to): I'm Alex, a Senior RPA & AI Developer. Pleasure to meet you! 👋 Organizations hire me when they need automation that actually moves numbers, not just "runs tasks." Over the last 8+ years, I've designed intelligent workflows that saved clients hundreds of hours per month, cut operational costs, and eliminated entire chains of manual work. I specialize in end-to-end automation for companies in finance, logistics, insurance, SaaS, and service operations. A few anonymized highlights: ✅ Built a document-processing workflow for an insurance client that reduced claim intake time from 3 hours → 14 minutes, saving $110K/year. ✅ Created a multi-step RPA system for a logistics company that eliminated 740+ hours of manual data entry every month. ✅Automated green-screen/AS400 interactions for a financial client, removing 98% of human entry errors and improving audit compliance. ✅ Developed an LLM-based email classification engine that handled 6,000+ monthly messages with 94% accuracy. ✅ Integrated modern SaaS systems with a legacy ERP to reduce reconciliation work by 80%. My clients appreciate my clarity, responsiveness, and ability to simplify complex systems into predictable automated processes. I enjoy the entire lifecycle - from mapping workflows to orchestrating AI-driven decision logic and deploying stable automations that run quietly in the background. I work with a small technical team (including a senior engineer), ensuring both high-level architectural guidance and expert implementation on every project. When you hire me, you get a blend of strategic thinking, precise execution, and enterprise-grade reliability. Looking forward to understanding your workflow challenges and helping you unlock real operational leverage. Cheers, Alex

I am a Senior Software Engineer and Team Lead with over a decade of experience delivering complex software systems for clients in the UK, US, and globally. For the past 7 years I have been contracting as a Senior Team Lead, managing a team of 3 engineers while running multiple client projects in parallel. My work has spanned SaaS platform development, cloud transformations, AI and machine learning integrations, and full legacy system modernization — delivering complex, production-grade software across the UK and US markets. This is the experience I bring to every project on Upwork. I now run Central Code Station, which means I can take on larger and more complex work than a solo freelancer while still being the person you communicate with directly. On Upwork specifically, I have 14 completed projects and a 5-star record — mostly Chrome extensions and web apps. Those projects represent a fraction of what I have actually built. The full picture is above. What we build well: - Custom web applications and SaaS platforms - AI and machine learning integrations - Legacy system modernization and cloud migration - Browser extensions and automation tools - System architecture and technical leadership If you need software built properly — on time, with clean architecture, and by someone who has done this at scale — let us talk.
