Alexander K.

Senior Cloud Architect/Engineer with years of experience designing large-scale, event-driven, and serverless platforms on AWS. Worked on large projects in a wide variety of business areas: e-commerce, healthcare, real estate market analysis, etc. **How I work** • Business-focused and strategic. Any architecture or engineering solution I develop is always driven solely by business requirements. I never begin development with the question, "How will we implement this problem?" The first step in solving any problem is clarifying the business requirements: "What does the business want to achieve, and how does this align with its long-term strategy and ROI expectations?" • Stakeholder Engagement I always strive to be a trusted technology advisor to my employer's business and its clients. In practice, this means I actively participate in all stages of discussions of business challenges or problems. During discussions, I strive to develop a clear and concise solution plan. I not only defend my opinion but also listen to others' ideas, adapting my own to theirs. Once the discussion is concluded and a decision is made, I get to work and do all my best to achieve the result, regardless of how closely the decision aligns with my initial vision. • Problem-solving and an analytical approach. My many years of experience have confirmed time and again: a problem requiring a solution rarely lies on the surface. More often than not, we see only its external manifestations, its symptoms. A real "cure" always requires an initial analysis, delving deeper into the root of the problem. And this requires analysis and meticulous attention to detail. Only then can I provide businesses with an innovative solution to their problem - and often, to several problems at once. • Proactivity. I never wait for a ticket to open before I start thinking and acting. I'm always closely monitoring everything happening in the company, the team, and the product. This allows me to propose innovations or anticipate problems long before they become one. • Leadership When leading a team or group, ensuring collaboration between cross-functional groups, I always strive to optimize interaction and communication processes as much as possible. My colleagues quickly became convinced that my suggestions in this area truly make life better, development and maintenance more predictable, and business more stable. In the vast majority of cases, I quickly gain credibility among my colleagues; they listen attentively to my recommendations and actively discuss them, which increases everyone's engagement in achieving optimal results. • Adaptability. Yes, to stay in place, you have to run very fast. This idea by L. Carroll is more relevant now than ever. Therefore, I spend 1-1.5 hours of my free time almost every day learning new tools, approaches, and technologies. This is especially true when joining a new team, where the lack of existing knowledge is always obvious. **A few facts about me** • AWS Well-Architected is my favorite framework. • Led cloud transformations from monoliths to serverless microservices, reducing operational overhead by 30–40%. • 12,000+ Upwork hours with 100% client satisfaction.
