Technology Stack
Who I am & what I do.
Full-Stack Developer specializing in high-performance Node.js and TypeScript ecosystems. I build scalable architectures on AWS that handle real production traffic—APIs processing 15k+ daily requests, ETL pipelines moving multi-GB datasets, and Next.js apps optimized for speed.
I focus on systems that are reliable and cost-effective. Whether reducing API latency by 40% or automating workflows that save clients 20+ hours per week, I deliver solutions that work at scale. My toolkit spans the full stack: React/Next.js on the frontend, Node.js/Express on the backend, PostgreSQL for data, and AWS for infrastructure.
What I work with:
Backend Engineering
Node.js, Express.js, REST APIs, TypeScript, Python Scripting
Frontend Development
React.js, Next.js, TypeScript, JavaScript, HTML/CSS, Responsive Design
Database Management
PostgreSQL, MongoDB, MySQL, SQL Optimization, ETL Pipelines
Cloud & DevOps
AWS (EC2, S3, RDS, Lambda, API Gateway, CloudWatch), Docker, Vercel
Development Tools
Git/GitHub, GitHub Actions, CI/CD, Jest, React Testing Library

Solutions That Drive Results
Engaging User Experiences
Launch high-performance marketing sites or SaaS dashboards that load in under 2 seconds and rank on Google. Built with Next.js and TypeScript—includes SEO optimization, CMS integration, and polished animations.
Reliable Data Pipelines
Stop losing data to broken imports. I build ETL pipelines that move multi-GB datasets reliably—reducing ingestion errors by 90% and cutting processing time by 75%.
Scalable & Secure Infrastructure
Enterprise-grade backend systems built for 99.9% uptime. RESTful APIs and microservices handling 15k+ daily requests with minimal latency—Node.js, Express, TypeScript.
High-Performance Databases
Slow queries killing your app? I optimize PostgreSQL, MongoDB, and MySQL through smart indexing, schema refactoring, and query tuning—typically improving performance by 25-40%.
Cost-Effective Cloud Solutions
Deploy to AWS with confidence. EC2, S3, RDS, Lambda—containerized with Docker, automated with GitHub Actions, monitored for reliability. Cut your infrastructure costs by up to 30%.
Intelligent Product Features
Add intelligence to your product. I integrate OpenAI, Anthropic, and custom ML models into production apps—with proper prompt engineering, error handling, and cost optimization.
On-Demand Solutionsfor_
Fixed-scope, high-impact engagements tailored for founders, product leaders, and engineering teams that need momentum without hiring full-time.
48-HOUR KICKOFF
Scope, roadmap, and integration check completed within two business days so work starts fast.
FIXED-SCOPE DELIVERY
Clear milestones, acceptance criteria, and hand-off playbooks—no ambiguous retainers.
OPERATOR EXPERTISE
Backed by production wins: 40% faster APIs, 90% fewer ingestion errors, and resilient CI/CD.
AI Model Integration
Need AI in your product? I integrate OpenAI or Anthropic models into your Node.js or Python backend with production-ready monitoring. You get: integration blueprint, API wrapper, secure key rotation, and QA checklist.
Targeted API Endpoint
Ship a single feature end-to-end: schema design, RESTful endpoint, auth hardening, and Postman-ready docs. You get: design spec, coded endpoint, tests, and deployment runbook.
Database Performance Audit
Is your app slowing down? I eliminate latency in PostgreSQL or MongoDB without a full rewrite. You get: diagnostic report, prioritized fix plan, and before/after benchmarks.
CI/CD Pipeline Setup
Automate your deployments with GitHub Actions. You get: pipeline architecture, workflows, environment gates, secrets management, and a hand-off training session.
