UA Corp
Solutions Architect (Ad Tech & MarTech)
UA Corp is an engineering company specializing in software solutions for the digital advertising industry. The company creates systems capable of handling high workloads: when developing them, it uses technologies that are optimally suited to solving a specific problem, rather than simply following the latest trends. UA Corp’s solutions strike a balance between development speed and product quality, ensuring the product won’t become a nightmare for technical support just six months down the line.
UA Corp works on a wide range of projects, including the creation of new digital products, the modernization and improvement of existing systems, and integration with modern advertising platforms and third-party services.
By combining deep engineering expertise with an understanding of the digital advertising ecosystem, UA Corp helps create solutions that scale exactly when needed—rather than crashing during peak loads when many people are watching the system in action.
Solutions Architect, Aug 2026 - Present
Following a successful track record of delivery as an Engineering Manager, I am transitioning into the Solution Architect role to oversee the long-term technical vision, governance, and cross-project architectural integrity of our enterprise ecosystem.
Key Focus Areas & Objectives:- Enterprise Architecture Design: Defining high-level architectural patterns, blueprints, and standards for complex microservices, serverless, and multi-cloud systems (GCP, AWS, Custom On-Prem/Providers).
- Cloud & Infrastructure Governance: Designing resilient, fault-tolerant hybrid cloud environments, optimizing data flow between relational (MySQL) and real-time (Firebase) data stores, and establishing unified security/identity protocols (OAuth 2.0, Secret Management).
- TCO Optimization: Leading technical audits to minimize cloud spend, improve resource utilization, and maximize performance across all product lines.
- AI Strategy Alignment: Scaling the capabilities of the internal AI Hub to deeper integrate generative AI and automation into core business processes safely and efficiently.
- Compliance & Technical Security: Ensuring all architectural solutions align with strict industry regulations and security compliance frameworks for private and restricted API integrations.
- Technology Evaluation & Mentorship: Guiding the technology selection process by establishing architectural evaluation frameworks, leading PoCs, and mentoring engineering teams on design patterns, scalability, and code quality.
Engineering Manager, Feb 2025 - Aug 2026
Led end-to-end engineering strategy and execution for a complex, multi-tier enterprise application, managing cross-functional teams and orchestrating a multi-cloud infrastructure. Successfully drove the product from initial architecture to compliance readiness, resulting in a promotion to Solution Architect.
Leadership & Strategy:- Team Management: Led 3 core teams (UI, Node.js API, Python API) and specialized temporary squads (Secret Manager, AI Hub).
- Stakeholder Engagement: Partnered with Product Management on specs and key stakeholders on budgeting, timelines, and TCO optimization.
- R&D & Innovation: Organized internal hackathons to benchmark framework performance, scalability, and extensibility.
- Compliance: Spearheaded technical preparation and audits to pass a rigorous compliance process, securing access to a restricted private API.
Architectural Highlights:- Multi-Cloud & Serverless: Designed a highly available architecture across 4 environments (GCP, AWS, 2 custom providers) leveraging serverless tech.
- Data & Security: Managed dual databases (MySQL & Firebase RTDB). Integrated enterprise OAuth 2.0 and a custom Secret Manager.
- AI Automation: Developed an AI Hub to automate business processes and streamline Node.js API requests.
- Cost Optimization: Continually optimized solution architecture, maximizing performance while drastically reducing infrastructure costs.
Tech Stack: Node.js, Python, React/Angular, MySQL, Firebase, OAuth 2.0, Serverless, GCP, AWS.
