ABOUT

I Don't Just Write Code.
I Architect Bulletproof Systems.

I'm a full-stack developer who operates at the intersection of complex backend logic and high-performance frontend execution. My work isn't defined by the frameworks I use — it's defined by the problems I obliterate.

From engineering fault-tolerant database schemas with Row Level Security policies to debugging silent deployment failures on edge networks at 2 AM — I handle the entire lifecycle. I don't hand off problems. I own them, from git init to production.

Every system I build is designed under one assumption: it will be attacked, it will face edge cases, and it will need to scale. I architect for that reality.

SPECIALTIES

Core Architecture &
Engineering Domains

System Architecture

Building decoupled, hybrid, and serverless applications that separate concerns cleanly. I design systems where the frontend, API layer, and database can evolve independently — ensuring zero-downtime deployments and horizontal scalability from day one.

MicroservicesServerlessEvent-Driven

Database Engineering

Structuring relational data for performance and security. I write Row Level Security (RLS) policies that lock data at the row level, design normalized schemas that prevent data anomalies, and build fault-tolerant ingestion pipelines.

PostgreSQLRLS PoliciesSchema Design

API & Integration

Engineering seamless data flow between frontends, third-party services, and backend databases. From SMTP email triggers to webhook-driven automation, I build integrations resilient to upstream failures with full audit logging.

Performance & Edge

Optimizing for speed at every layer — from image compression and lazy loading to CDN caching strategies and edge-network deployment. I manage complex environment variable chains to ensure zero-leak security.

PHILOSOPHY

Engineering
Mindset & Principles

01

Assume Failure. Build Fallbacks.

Every external API will timeout. Every database query will face a deadlock. I don't hope for the best — I engineer for the worst. Every system I ship has graceful degradation, retry logic, and meaningful error boundaries.

02

Clean Code Over Clever Code.

A one-liner nobody can debug at 3 AM is a liability, not a feature. I write code that reads like documentation — self-explanatory names, single-responsibility functions, and comments that explain why, not what.

03

Debug the Environment, Not Just the Code.

The hardest bugs live between systems — misconfigured environment variables, silent CORS failures, edge-network caching stale secrets. I diagnose at the infrastructure level first, because the code is often correct; it's the deployment context that's lying.

Case Studies

Lead Developer

Enterprise Dashboard Platform

The Business Problem

A mid-size logistics company needed a real-time operations dashboard aggregating data from 5+ internal APIs, with role-based access for 200+ employees across 3 departments.

Technical Stack

Next.js 15SupabasePostgreSQLTailwindCloudflare

Architecture

SSR with Next.js App Router feeding real-time Supabase subscriptions. PostgreSQL with RLS enforcing department-level data isolation. Edge-deployed on Cloudflare.

The War Story

API keys silently failing on Cloudflare's edge runtime — variables weren't forwarded to server components at build time. App worked locally, empty data in production. Fix: explicit runtime scoping with NEXT_PUBLIC_ prefix patterns and server-only secret injection.

Solo Architect

Secure Client Portal & CRM

The Business Problem

A consulting firm required a client-facing portal for request submission, project tracking, and automated email notifications — with strict inter-client data privacy.

Technical Stack

React.jsSupabase AuthPostgreSQLSMTPFramer Motion

Architecture

React SPA with Supabase Auth magic-link login. PostgreSQL RLS ensuring Client A cannot see Client B's data. DB triggers firing Edge Functions for transactional emails.

The War Story

Email triggers silently failing — Edge Function executed but emails never arrived. Root cause: SMTP provider rejected Supabase's edge IP range (SPF misalignment). Fix: custom SMTP relay with proper SPF/DKIM/DMARC records + dead-letter logging.

Full-Stack Developer

High-Performance Portfolio Engine

The Business Problem

Build a developer portfolio that isn't just a static page — a high-performance interactive experience with cursor-tracking animations and a perfect Lighthouse score.

Technical Stack

ViteVanilla JSCSS MasksSVGrAF

Architecture

Zero-framework approach for max performance. CSS custom properties driven by rAF loop for 60fps mask animations. SVG topographic patterns with CSS keyframe animations.

The War Story

CSS mask-image with radial-gradient caused full layer recomposites each frame. Fix: moved mask coordinates to CSS custom properties updated via style.setProperty(), isolating changes to compositing layer only.
