ABOUT ALEXANDER KIRILIN
As a senior engineer who\'s built technical foundations for high-growth companies and consulted across finance, real estate, and private equity, I\'ve learned that the best architecture decisions come from deeply understanding the business problem first.My background combines hands-on execution with strategic thinking across industries. I\'ve been lead engineer at a B2B SaaS startup, built AI platforms, designed systems for hedge funds and real estate firms, and conducted technical due diligence for venture-backed companies. In each case, I was translating business requirements into scalable solutions and helping stakeholders understand architectural tradeoffs.I\'ve sat on both sides as technical co-founder, consultant, and engineer. I understand how investors evaluate technical risk because I\'ve conducted due diligence. I know what keeps finance teams awake because I\'ve built their analytics platforms. I architect solutions that work in real enterprise environments, not just theory.Through Shoobridge, I advise growing businesses on AI implementation—helping companies deploy AI to solve operational challenges. This consulting keeps me grounded in business constraints and organizational change management. This hands-on advisory work makes me a better architect because I understand the customer perspective deeply.Currently building AI automation at ESS while positioning for Solutions Architecture roles at companies solving complex problems at enterprise scale. I\'m drawn to pre-sales SA work where I can help customers understand how technical solutions map to business outcomes, design architectures for their environments, and serve as the technical voice turning evaluations into partnerships.My technical foundation spans AWS (Lambda, EC2, SQS, S3, Aurora RDS).NET, React, Vue.js, and performance optimization delivering real results—like increasing ETL throughput 330x. What excites me is solving business problems: cutting infrastructure spend fifty percent, automating bottlenecks, designing systems handling millions of events reliably.Whether you\'re building technology needing deep technical understanding to sell effectively, or exploring how AI can transform operations, let\'s connect.
