I help startups, SaaS companies, and product teams build scalable software, automate complex business workflows, and bring products from idea to production. Whether you're launching a new SaaS platform, scaling an existing product, integrating third-party services, or modernizing your infrastructure, I can own the entire development lifecycle, from architecture and database design to backend APIs, frontend development, testing, deployment, and long-term maintenance. My goal isn't just to write code. It's to help you ship faster, reduce technical debt, improve reliability, and build systems that continue to scale as your business grows. I frequently help clients with: • Building AI-powered SaaS products • End-to-end full-stack application development • Scaling Next.js, React, TypeScript, and Node.js applications • Designing PostgreSQL and Supabase architectures • Stripe and third-party API integrations • Workflow automation and AI-assisted engineering • Performance optimization and database tuning • CI/CD, cloud infrastructure, and deployment automation Core Stack Next.js • React • TypeScript • Node.js • PostgreSQL • Prisma • Supabase • AWS • Stripe • GitHub Actions • Playwright • Vitest Most recently, I served as a core Full-Stack Engineer on a large-scale creator and influencer marketing SaaS platform. As one of the project's highest-output contributors, I delivered 1,000+ production commits across a codebase containing 600+ API routes, 100+ PostgreSQL tables, and nearly 3,000 TypeScript files. Some of the business-critical systems I owned: ✔ Built a real-time creator community platform featuring groups, social feeds, collaborative quests, group chat, notifications, reactions, and engagement tools that increased platform activity and supported long-term creator retention. ✔ Developed a TikTok Shop affiliate integration that automated order synchronization, webhook processing, SKU backfilling, and GMV attribution, giving brands real-time visibility into creator performance without manual reconciliation. ✔ Designed reputation, leaderboard, badge, and gamification systems that automatically rewarded creator engagement and encouraged continued platform participation. ✔ Built creator onboarding and lifecycle automation, including referral tracking, multi-step email campaigns, creator dashboards, and self-service resource hubs that improved onboarding while reducing manual operations. ✔ Implemented secure authentication and authorization using role-based permissions, Supabase Row-Level Security (RLS), resource grants, protected routes, and account-linking safeguards to support enterprise-grade security. I also help engineering teams ship faster by building reliable development infrastructure: ✔ Automated CI/CD with intelligent GitHub Actions workflows ✔ Disposable Supabase and PostgreSQL environments for integration and RLS testing ✔ Automated quality gates for schema validation, dead code detection, security checks, complexity analysis, and route protection ✔ Branch-specific staging and production deployments with schema drift detection ✔ Performance optimization through indexing, query tuning, materialized views, advisory locks, optimized RLS policies, and connection pool optimization Beyond traditional development, I leverage modern AI-assisted engineering workflows using Claude Code, Model Context Protocol (MCP), parallel Git worktrees, automated task management, and agent-driven development to accelerate delivery while maintaining production-quality code, testing, and documentation. Earlier in my career, I built enterprise platforms across commerce, procurement, finance, compliance, SAP, cloud automation, and business process automation. I'm also an AWS Certified Developer with hands-on experience designing serverless architectures, Infrastructure as Code, scalable cloud-native systems, and production CI/CD pipelines. Clients value me because I don't just complete tickets, I take ownership of problems, communicate proactively, and deliver solutions that are secure, maintainable, thoroughly tested, and built for long-term growth. If you're looking for an engineer who can own complex features from concept to production while keeping quality, scalability, and business goals in focus, let's discuss your project.
