About / the developer

I build and scale SaaS platforms across fintech, e-commerce, marketing automation, and AI-powered products. My focus is backend architecture, performance optimization, and database design that doesn't fall over at 10× the load.
Over 3+ years I've shipped 10+ production systems, led refactoring initiatives, cleaned up legacy debt, and integrated the kind of third-party APIs that come with incomplete docs and surprises.

Rescue work / for vibe-coded apps

Shipped fast with AI tools and now something's on fire? I come in, stabilize the codebase, close the security gaps, and hand it back in a state you'd actually want to hire a team around.

01 · service
Security audit
Find and patch the holes AI coding tools love to ship: exposed secrets, missing auth checks, SQL injection surface, unvalidated inputs, leaky CORS, insecure direct object refs.
OWASPAuthSecrets
02 · service
Production bug triage
Your app works on localhost, crashes in prod. I reproduce, isolate, and fix the race conditions, N+1 queries, memory leaks, and silent failures that only appear under real load.
DebuggingPerfObservability
03 · service
Codebase cleanup
Duplicated logic, dead routes, copy-pasted components, inconsistent patterns. I extract, consolidate, and document so the next feature doesn't break three others.
RefactorDXDocs
04 · service
Re-architecture
When the app outgrew its first draft. Schema redesign, service boundaries, async workflows, queue introduction — done incrementally, never big-bang.
ScaleSchemaQueues
You probably need this if…

Any of these feel familiar? The longer they sit, the more expensive they get.

  • [01]Cursor / Copilot wrote most of the backend
  • [02]Nobody's touched the DB migrations in months
  • [03].env is in the repo (or was)
  • [04]Shipping new features keeps breaking old ones
  • [05]Mystery 500s you can't reproduce locally
  • [06]Auth logic is scattered across 12 files
  • [07]One endpoint takes 14 seconds
  • [08]PR reviews are 'LGTM' with zero comments
01 · Audit
2–3 days
Full walkthrough: repo, infra, DB, auth, logs. Written report.
02 · Triage
ongoing
Prioritize by blast radius — security first, stability second, debt third.
03 · Fix
1–6 weeks
Incremental PRs. Every change reviewed, tested, shipped safely.
04 · Handoff
1 week
Documentation, runbooks, and a plan your team can keep executing.

Expertise / what I do well

A · 01
Backend Architecture
Service design, API boundaries, async workflows, background jobs. Built for horizontal scale, not heroic scaling.
B · 02
Database Design
Schema modeling in PostgreSQL, MySQL, SQLite. Query shape matters more than the ORM. Indexes earned, not sprinkled.
C · 03
Performance & Refactoring
Led incremental re-architecture of legacy monoliths. Measure, isolate, replace. No big-bang rewrites.
D · 04
LLM Integration
OpenAI GPT workflows for structured extraction, scraping, and content pipelines. Prompts as code, tested like code.
E · 05
Frontend Engineering
React, Next.js, TypeScript, Tailwind. SSR, SEO, and the unglamorous parts of shipping UI that actually converts.
F · 06
Third-party APIs
Stripe, Tap, Meta Graph, LinkedIn. Resilient integrations with retries, idempotency, webhook replay — the stuff docs skip.
G · 07
DevOps & Infra
AWS EC2, S3, container deploys, CI pipelines. Enough to own the stack end-to-end without needing to file a ticket.
H · 08
AI Pair Programming
Working alongside Claude Opus and Copilot agents. Offloading boilerplate, staying senior on architecture and review.
