Software Engineer | System Architect | AI, SaaS, DevOps

For over 18+ years I have built a proven track record of delivering enterprise solutions for government agencies, startups, and Fortune 500 companies. My specialty lies translating complex business requirements into high-performance platforms that actually scale. With my experience I can cover the full software development lifecycle. From software architecture, cloud infrastructure, frontend frameworks, AI integration, and DevOps automation. I build systems that don't just work today, but are architected to scale for years Technical Expertise: ▪ Frontend: React | Next.js | Astro | Remix | Tailwind CSS | shadcn/ui ▪ Backend: Node.js | Express | Hono | TRPC | Firebase | Supabase | FastAPI ▪ Database: PostgreSQL | MongoDB | Redis | DynamoDB ▪ CMS: Payload | Sanity | Strapi | Contentful ▪ Cloud & DevOps: AWS | SST | Docker | Terraform | Pulumi | GitHub Actions ▪ AI Integration: OpenAI | Anthropic | RAG Pipelines | Vector Search Services I provide: ▪ Full-Stack Development: API | Web & Mobile Apps | SaaS Platforms | Cloud Architecture ▪ Growth Solutions: Product Development | Gap Analysis | Project Management ▪ Systems Optimization: Performance Audits | Refactoring Legacy Code ▪ Fintech & eCommerce: Stripe Connect | Shopify | Custom Shop | Escrow Systems ▪ Automation & AI: LLM Integration | Custom Scrapers | Workflow Automation Building a successful business is hard enough without fighting your own technology. Most growing platforms hit a wall where "vibe-coding" and rapid patches create a ton of tech debt that kills momentum. I help teams move past that phase and into a structured, automated release cycle that eliminates broken deployments and unreliable code. When we partner, you can expect: ▪ Zero-Downtime Reliability: I implement CI/CD and IaC so your platform stays stable as we scale. ▪ Gap Analysis & Roadmap: A clear audit of your current state and a prioritized plan for your goals. ▪ Clean Architecture: I build layered, maintainable systems instead of technical debt for your team. ▪ Total Accountability: No missed deadlines, no hidden fees, and no "black box" development cycles. Given my proven track record I am confident I will be an asset to your organization. Don't risk the success of your next project with a novice freelancer!
