Capabilities

Leading initiatives from architecture vision to polished delivery.

I partner with product and platform leads to turn growth goals into resilient systems, intuitive touchpoints, and calm delivery rhythms.

Backend & Platform Architecture

Design distributed, AI-ready platforms so revenue-critical systems stay accurate, resilient, and easy to evolve.

  • Microservice design in Node.js, FastAPI, and Spring for the core flows
  • API governance, zero-trust defaults, and tuned integrations
  • Observability, SLOs, and AI-assisted ops that guard uptime

Frontend & Product Experience

Turn complex platforms into clear, accessible interfaces the whole company can iterate without friction.

  • Next.js + React systems with reusable tokens and docs
  • Micro-frontend orchestration and editor tooling
  • Accessibility-first patterns with strict perf budgets

Cloud & DevOps Enablement

Automate delivery, analytics, and support loops so teams stay focused on customer value instead of firefighting.

  • AWS, GCP, Firebase, Vercel, and Railway envs with guardrails
  • Continuous delivery pipelines and predictable releases
  • Incident playbooks and postmortems that actually get applied

Preferred stack

Tooling I reach for when pace and stability both matter.

Proven impact

Proof points from AI-enabled commerce, healthcare, and platform transformations.

I turn architecture strategy into measurable wins—modern stacks, AI-accelerated delivery, and steady operators. These receipts show the scale and accountability I carry.

Operating principles

How I go from vision to shipped outcomes.

I blend systems thinking with calm execution—align early, challenge assumptions, and keep improving.

Outcome-driven architecture

Start with the KPI, architect for reliability, and adjust from telemetry before polishing anything else.

Strong opinions, loosely held

Show up with a point of view, then adapt fast through pairing, reviews, and production signals.

Clarity is compassion

Keep tickets, runbooks, and direction crisp so the team stays unblocked and confident.

Delivery cadence

A loop designed for predictability and learning.

1

Discover & Align

Frame the problem, success metrics, and constraints with stakeholders before writing code.

2

Architect & Socialize

Share architecture narratives and sequencing to earn buy-in across product, security, and infra.

3

Execute & Elevate

Run delivery with code reviews, testing, and mentoring that raise the bar for the team.

4
