I architect and ship full-stack JavaScript products — React, Node.js, TypeScript — on AWS. 19 years in production. Top Rated: 15+ jobs, 100% feedback, $200k+ earned. I take legacy or greenfield systems and leave you a platform a real team can run.
What I can do for your business:
• A full-stack JavaScript platform you can run — React, Next.js, Node.js on AWS and Kubernetes, wired to Salesforce, MongoDB, PostgreSQL, Redis, DynamoDB. New product, or a legacy rewrite that does not stop operations.
• Less manual work. I build AI automations and in-product LLM features (APIs, Bedrock, copilots) for the repetitive processes that block growth — not a chatbot bolted on the side.
• A team that stays fast after I leave. I install a shared AI practice in the repo: skills, rules, and memory for Cursor and Claude Code. Agents plan, build, and review against your conventions, security, and tests. Everyone prompts the same way. The practice stays when the contract ends.
• Judgment on top of generated code. AI writes a lot of the function. You hire for what a model cannot do: what is worth building, whether it helped the business, and what we must not break.
Recent staff work at that level: I owned a 20+ service AWS/Kubernetes platform, migrated PHP/jQuery to React, Next.js, and Node.js, and built the skills/rules/memory pack the team ships with.
How I work with you:
• Solution owner, not ticket-taker. I get close to the business problem, decide, build, and confirm it worked. Ticket count is not the measure.
• Review moves earlier — architecture and risk — while changing course is still cheap. Agents review the change; I put judgment on top. I do not hand you an unread 4,000-line PR.
• Trust but verify: tests, CI, staged rollout, monitoring, fast rollback. The person who shipped it owns it.
• Migration is not a port. We make the process better and automate what people still do by hand.
• Honest estimates, English every day, written decisions, security in the build (auth, secrets, least privilege).
Before that, I spent 4+ years as a Top Rated Upwork architect for English-speaking clients. I scoped the work, negotiated the contract, designed the software and the data model, wrote the code, and stayed on for support. Typical jobs were React, Node.js, and React Native apps; REST and GraphQL APIs; OAuth and JWT; Salesforce integrations; and AWS delivery (CI/CD, serverless, Docker, Amplify, CDN). I also rewrote and stabilized legacy JavaScript and PHP without stopping the business.
I co-founded a software company and ran it as CTO—teams of up to 15, and I negotiated about 80% of the contracts myself. Before that, I was a senior full-stack JavaScript and PHP engineer at an outsourcing shop (100+ projects) and a senior PHP developer who grew into architecture, Linux, and AWS.
The thread through all of it: full-stack JavaScript, SQL and NoSQL architecture, AWS and DevOps, and turning messy systems into software people depend on every day.
Stack I use most: JavaScript, TypeScript, React, Next.js, Node.js, Express, MongoDB, PostgreSQL, Redis, DynamoDB, Salesforce, AWS, Kubernetes, Docker, CI/CD, GraphQL, REST, Cursor, Claude Code.
If you need an architect who still writes the code — and leaves you a team that can keep shipping with AI — send the brief. I will tell you quickly whether I am the right fit.
