With over 15 years building & scaling distributed systems—including extensive AWS experience with SQS, SNS, ElastiCache, RDS, & ECS—I bring deep expertise in messaging, caching, & low-latency data-sharing platforms. At Remind, I managed infrastructure supporting millions of teachers & students, implementing pub/sub patterns with SQS, optimizing Redis caching strategies, & scaling critical services during COVID-19 lockdowns using CloudFormation & infrastructure-as-code. I've also contributed to Ruby-based tooling (SlashDeploy at Remind enabled GitHub deployments via Slack commands, pioneering automation before modern CI/CD platforms existed) & have strong Python experience across Flask, Pyramid, & async job processing systems. My work spans the application-infrastructure boundary: designing CI/CD pipelines at Coursemojo, implementing Terraform-based AWS controls at Cofense, & building self-service deployment tools that empower engineering teams. + +As a founder of multiple SaaS platforms (Remarkbox, Make Post Sell), I've lived the challenges of building frameworks & tooling that reduce operational overhead while maintaining reliability at scale. I've designed async job processing systems, implemented PII masking & security patterns, & built shared libraries for logging, tracing, & monitoring across distributed services. My experience with GitLab CI runners (used across all my self-hosted projects at git.unturf.com) gives me deep understanding of CI/CD automation, self-service tooling, & developer productivity improvements. I've consistently focused on making engineers more effective: at Remind, I authored technical blog posts on infrastructure migration & best practices; at Coursemojo, I built teacher dashboards with real-time activity control; everywhere, I've prioritized clear documentation & reusable patterns that scale across teams. + +What excites me most about Chime is the mission to help everyone achieve financial progress through accessible technology. I've spent years building tools that democratize access—whether it's commission-free e-commerce for small sellers (Make Post Sell with hot wallet crypto payments), privacy-focused commenting for independent publishers (Remarkbox), or AI-powered education tools for public schools (Coursemojo). I'm eager to bring my experience architecting messaging platforms, optimizing AWS infrastructure, & building developer-facing frameworks to help Chime's engineering teams move faster & more reliably. Please keep me in your considerations for growing solutions at Chime! diff --git a/content/pages/cover-letters/2025-10-28-gitlab.txt b/content/pages/cover-letters/2025-10-28-gitlab.txt new file mode 100644 index 0000000..389c158 --- /dev/null +++ b/content/pages/cover-letters/2025-10-28-gitlab.txt @@ -0,0 +1,11 @@ +GitLab - Staff Backend Engineer, AI Engineering: Code Creation +================================================================ + +:date: 2025-10-28 +:slug: gitlab-staff-backend-engineer-ai-cover-letter + +I'm excited to apply for the Staff Backend Engineer - AI Engineering position at GitLab. With over 15 years architecting & scaling distributed systems—combined with deep Python expertise & hands-on AI integration experience—I bring the technical depth this role demands. At Coursemojo, I designed CI/CD pipelines for AI microservices, scaled language model integrations (OpenAI & Anthropic), & built real-time educational tools processing thousands of concurrent AI requests. I've also authored "uncloseai.com: Machine Learning Reference Guide to Inference Clients," documenting AI inference client implementations & streaming techniques across 42 programming languages—giving me comprehensive understanding of how different languages interact with AI models. My experience building high-performance APIs (Flask, Pyramid, uWSGI), optimizing database queries (PostgreSQL, MySQL, DynamoDB), & architecting containerized deployments directly aligns with GitLab's code creation tooling goals. + +As a long-time GitLab power user, I've built & maintained self-hosted GitLab infrastructure managing all my production systems—from remarkbox.com to makepostsell.com to uncloseai.com. I use GitLab CI runners in every repository to drive automated builds, tests, & deployments, giving me intimate operational knowledge of GitLab's architecture, runner orchestration, & CI/CD workflows. This hands-on experience—combined with my AWS infrastructure expertise (CloudFormation, ECS, Lambda) & my work scaling critical education services during COVID-19 lockdowns at Remind—positions me to make immediate contributions to GitLab's AI-powered DevSecOps platform. I've also open-sourced complete SaaS platforms (Remarkbox, Make Post Sell), demonstrating my commitment to transparent, maintainable systems that scale—values that align perfectly with GitLab's open-core philosophy. + +What excites me most about GitLab is the mission to enable everyone to contribute & co-create software. I've spent years building tools that amplify developer productivity (SlashDeploy at Remind pioneered Slack-based deployments before modern CI/CD platforms) & I'm passionate about how AI can accelerate the software development lifecycle without sacrificing code quality or security. I'm eager to bring my staff-level systems thinking, AI/ML integration experience, & deep understanding of GitLab's platform to help architect the next generation of AI-powered coding assistance. I'd love to discuss how my background building scalable APIs, optimizing performance-critical systems, & mentoring engineering teams can accelerate GitLab's AI Engineering roadmap.
