Arthur Wilk

I’m a Senior Full-Stack Software Engineer with 10+ years of experience designing and building scalable web and cloud-based applications. I specialize in modern frontend and backend frameworks and focus on delivering efficient, maintainable solutions.

In my current role at BNY Mellon, I developed a SaaS application using Next.js, Java, PostgreSQL, Tailwind CSS, and Stripe—integrating AI via Anthropic Claude and hardening security across the stack. I optimized backend services for stateless AWS Lambda deployment, reducing cold start times by ~40% while keeping operational performance strong.

I also lead architecture and implementation work that improves safety and usability: context management so the AI can remember prior conversations without polluted context, secure storage using RDS and KMS for sensitive keys/passwords, and messaging storage designed to prevent leaks even if the database is compromised. I’ve built secure authentication (JWT with AWS KMS signing), advanced infrastructure using Terraform, and monitoring-ready deployments with CI/CD.

Previously at Verizon Wireless, I delivered serverless data processing pipelines (SQS, Lambda, S3) and cross-cloud replication, built a Stripe metered billing integration, and created analytics APIs for researchers using Node.js, AWS Lambda, API Gateway, and PostgreSQL. I bring a practical, systems-focused approach—modernizing legacy systems, writing tests with strong quality practices, and collaborating closely with clients to solve complex technical challenges.
