Need a backend that scales without breaking integrations or security? With 12+ years building SaaS backends and APIs, I’ve delivered 99.9% uptime systems and cut checkout latency from 1.2 s to 450 ms for startups and SaaS teams. I build secure, production-ready Laravel and Node.js backends with API integrations, payments, and automation.
🎯 HOW I CAN HELP YOU
BACKEND SYSTEMS DEVELOPMENT
Build a backend that supports growth without slowing down your product. You get a secure, scalable foundation for SaaS, MVPs, and complex business apps, with architecture proven to handle high traffic, microservices, and zero-downtime releases.
API INTEGRATION
Connect your product to the tools your business depends on and reduce manual work fast. I’ve delivered production integrations with Stripe, PayPal, Twilio, Shopify webhooks, and custom third-party systems, including setups that handled 10k+ calls per hour.
SAAS DEVELOPMENT
Turn your idea into a production-ready SaaS product that can handle real users and revenue. My work has cut checkout latency from 1.2 s to 450 ms and supported billing, subscriptions, RBAC, and multi-tenant systems built for scale.
AUTHENTICATION AND SECURITY
Protect your application with login and access control users can trust. I implement OAuth2, JWT, SSO, and role-based permissions for apps that need secure access across teams, tenants, or multiple products.
AI API INTEGRATION
Add AI features that create product value instead of experimental complexity. I integrate OpenAI, Claude, Gemini, and custom LLM workflows for smarter search, document Q&A, automation, and assistant-style experiences.
🏆 RESULTS

Blazing-Fast Websites & Apps | Web Performance Expert | React | Next.js | Vite | Node.js | Deno | Bun
Need a website or app that doesn’t just work, but feels fast—and ranks well?
I help startups and businesses build modern, scalable web products with a focus on Core Web Vitals, UX, and real-world performance. If you’re dealing with slow load times, poor Lighthouse scores, or SEO issues, I can optimize your product end-to-end—from frontend rendering to backend performance and infrastructure.
What I do
Performance-first development
If Core Web Vitals are struggling, TTFB is slow, or your bundle is too heavy, I’ll improve performance across the stack: rendering strategy, JavaScript payload, caching, images, fonts, API efficiency, and deployment setup.
Full-stack delivery
Frontend: React, Next.js, Vite, Tailwind, TypeScript
Backend: Node.js, Express, Serverless
Database/ORM: Prisma, Drizzle, PlanetScale, Supabase, Neon
Auth: NextAuth, Clerk, Auth.js
Hosting/Infra: Vercel, Netlify, AWS, Google Cloud
SSR, CSR, SSG, ISR—right tool for your use case
I’ll recommend the best approach based on your goals:
• SEO-heavy pages and strong first load: SSR/SSG/ISR (Next.js)
• App-like experiences with dynamic UI: CSR (Next.js or Vite)
• Fast development, simpler architecture, SPA-first apps: Vite
You’ll get clear trade-offs, and an implementation that matches your product needs.
Practical tech choices
Not sure about Supabase vs PlanetScale, Prisma vs Drizzle, or REST vs GraphQL? I’ll help you choose what fits your team, timeline, and scaling requirements—without overengineering.
Business-minded execution
I focus on outcomes: shipping reliably, communicating clearly, and building maintainable systems that don’t turn into a mess later.
Services
• Web and app development (React, Next.js, Vite)
• Performance audits and optimization (Lighthouse, Core Web Vitals)
• Authentication setup (NextAuth, Clerk, custom solutions)
• API and backend integration (REST, GraphQL, Node.js)
• Database design and implementation (Prisma, Drizzle, Supabase, PlanetScale)
• SEO improvements via SSR and dynamic rendering
Why work with me
• 100% job success, 2000+ hours on Upwork
• Quick responses, clear communication, reliable delivery
• Business-first, results-driven approach
• No fluff—clean, maintainable, efficient code
Want a product that’s genuinely fast, scores well on Web Vitals, and scales without becoming a maintenance headache? Let’s talk.

I build SaaS platforms that scale - from zero to enterprise-ready, with a proven track record. Architecture, payments, real-time features, AI integrations, security audits - I own the full stack without hand-holding.
I've taken products through the full lifecycle: architecting the MVP, scaling for rapid growth, and passing security audits including CASA Tier 3 - Google's highest-tier cloud application security assessment, reserved for applications handling sensitive user data.
CORE STACK & AREAS OF EXPERTISE
• FRONTEND: Expert-level React / Next.js (TypeScript). Deep experience building accessible (ADA/WCAG compliant) and high-performance UIs.
• BACKEND: Scalable APIs, real-time services (websockets/streaming) and distributed job queues using Node.js (TypeScript) / Bun / Deno. I also leverage Rust and Go for performance critical services.
• AI & AGENTIC FEATURES: Integrating LLM-powered features and building agentic workflows into applications. Recent experience adding agentic capabilities to a SaaS product.
• DATABASES: Strong preference for PostgreSQL (self & cloud-managed, Supabase & PlanetScale) for its extensibility (PostGIS, pgvector for AI/RAG, timescale, etc.). Type-safe data modeling (Prisma, Drizzle or Kysely). Redis for caching, distributed locking, Pub/Sub, rate limiting.
• PAYMENTS & BILLING: I've built reliable revenue pipelines using Stripe (Subscriptions, Connect, Webhooks & other features in the Stripe ecosystem)
• DEVOPS & CLOUD: I build automated CI/CD pipelines (GitHub Actions) for testing & deploying to AWS, GCP, Azure, Vercel and other PaaS.
• DESKTOP: I use Tauri for lightweight, cross-platform desktop applications (and Electron for broader compatibility).
• TESTING & QA: E2E testing using Playwright, Appium for mobile (iOS/Android), and Vitest/Jest for unit/integration tests. React Testing Library and Storybook for further testing / component-driven development.
==================================
TEAMWORK / COMMUNICATION
• FOUNDER MINDSET: In my experience, being able to explain the 'why' behind technical choices so leadership can make informed decisions is crucial. This has naturally made me very comfortable communicating with stakeholders.
• AGILE & SDLC: Familiar with Agile/Scrum events and using development tools to manage sprints and documentation.
• ASYNC COMMUNICATION: I understand and value the importance of proactive communication, thorough PR reviews and documentation.
==================================
APPLICATION SECURITY & COMPLIANCE
• CASA TIER 3: Proven track record of meeting the highest security standards for SaaS applications, including passing Google’s Cloud Application Security Assessment Tier 3.
• APPLICATION SECURITY: I follow OWASP best practices to protect against vulnerabilities. Securely handling of OAuth2/OpenID Connect flows for social login (Google/Microsoft/etc. OAuth), for stateless and stateful authentication.
• COMPLIANCE: I build with ADA/WCAG and security frameworks in mind, ensuring that your application is ready for enterprise-level audits from day one.
• DATA PROTECTION: Proper handling of application secrets (Vault, AWS Secret Manager, Infisical, etc.), built role-based access control (RBAC) systems. I also ensure data is encrypted at rest & in transit, and use of advanced cryptography for storing highly sensitive data.
==================================
INFRASTRUCTURE & NETWORKING
• Linux Server Administration (AWS EC2, GCP, Azure & other VPS providers), IaC, virtualization (Proxmox, ESXi), containerization (Docker/LXC) - using compose and swarm for deployments.
• DNS / DOMAIN MANAGEMENT: Deep experience understanding of how DNS/HTTP(s) works, including subdomain routing, SSL certificates, and global traffic distribution (Cloudflare, Route53).
• EMAIL INFRASTRUCTURE & DELIVERABILITY: Expert at configuring SPF, DKIM, and DMARC records to ensure 100% email deliverability. I’ve managed migrations and setups for Google Workspace, Microsoft 365, and providers (SendGrid, Resend, Amazon SES and more).
==================================
If you need a developer and/or partner who understands the "why" behind the "how" - let’s talk!

A little more about me:
Working in tech is my dream job. I genuinely enjoy what I do, and I love learning and keeping up with new tech. What all started as a small "home lab" in my room, has turned into building mind blowingly complex software and I'm extremely grateful for this journey. When I’m not at my desk, you’ll find me on long-distance cycling trips - sometimes I wish there were more hours in the day!
