$100M+ in Client Revenue | Expert-Vetted (Top 1% Upwork) | 240+ Projects | 100% Job Success | 10+ Years on Upwork
I’m a Full Stack Developer, SaaS Developer and Backend Developer focused on building production-ready software that holds up under real-world usage. My work sits at the intersection of software developer, web developer, and SaaS platform builder, with a strong backend-first mindset and deep attention to scalability, performance, and long-term maintainability.
As a Full Stack Developer, I take ownership of systems end-to-end, pairing robust backend architecture with clean, modern interfaces. My frontend work is typically React-based and I often collaborate with or replace traditional React developer or web developer setups by owning both frontend and backend in a single, coherent system. While I’ve previously worked as a WordPress developer and integrated WordPress-based sites into custom platforms, my current focus is on custom SaaS and API-driven systems rather than CMS-centric builds.
As a SaaS Developer, I help companies design, build and scale SaaS products, internal tools and API-driven web applications intended for long-term use. My experience as both a Backend Developer and software developer allows me to think beyond features and focus on architecture, reliability and operational stability from day one. Many of the platforms I build support internal teams, customer dashboards and multi-role workflows where permissions, data integrity and business rules are critical.
In my day-to-day work as a Backend Developer, I design and implement backend services, APIs and data models that power SaaS platforms, complex web applications and mobile-connected systems. I regularly work with Node.js and Python, drawing on my background as a Python developer to build scalable services, background jobs and asynchronous workflows that perform reliably in production.
As a Full Stack Developer, I ensure these backend systems integrate cleanly with frontend applications, mobile extensions and third-party APIs. When required, I support frontend and mobile app developer workflows using React and React Native. This end-to-end ownership is a key reason clients bring me in as a Full Stack Developer rather than splitting work across multiple roles.
A significant portion of my work as a SaaS Developer and Backend Developer involves building internal platforms, dashboards and API-first systems that integrate external services. In these projects, I often collaborate closely with product, growth, or analytics teams, including teams focused on SaaS marketing by designing clean data pipelines, event tracking and backend logic that supports experimentation, reporting and lifecycle insights.
When projects require AI-powered functionality, I bring hands-on experience integrating AI into backend systems. While my primary role remains Full Stack Developer and Backend Developer, I regularly implement AI-enabled workflows, data processing pipelines and LLM-driven features inside SaaS platforms. This allows me, as a SaaS Developer, to deliver AI functionality that is reliable, observable and cost-controlled rather than experimental.
Clients typically work with me when they need:
- a Full Stack Developer who can own frontend and backend
- a SaaS Developer who understands long-term scalability constraints
- a Backend Developer experienced with real production systems
- mobile app developer and React developer experience as a software developer
- backend services built with Node.js or Python by an experienced Python developer
- web applications with complex workflows and business rules from a senior web developer
- API-driven architectures and third-party integrations
- SaaS platforms designed to support growth, analytics and SaaS marketing data needs
- MVPs that can realistically evolve into long-term SaaS products
A large part of my work as a Full Stack Developer, SaaS Developer and Backend Developer focuses on:
- multi-role dashboards and internal tools
- authentication, authorization and permissions
- API-first backend system design
- integrations with external platforms, including legacy CMS or WordPress-based systems when required
My core work as a Backend Developer and Full Stack Developer covers:
- backend services built with Node.js and Python
- APIs, background jobs and integrations
- databases such as PostgreSQL
- modern stacks using tools like Supabase
- AI-enabled backend features where they add real business value
I regularly work on MVP builds and early-stage products as a SaaS Developer, with strong focus on solid backend foundations, sensible scaling paths and avoiding short-lived prototypes. Based on scope and timing, I work hands-on as a Full Stack Developer, SaaS Developer and Backend Developer and when useful, involve specialists from my team.
Long-term results come from clarity and intentional system design. I focus on delivering software that teams can confidently run, maintain and scale.

• QA + DevOps + 30- 45 days post-launch warranty included, never upsold
One contract, one team, one accountable lead. No vendor coordination tax.

A $100M+ MENA delivery platform with 10M+ users; an $11M-funded India fintech; KSA's top luxury e-commerce brand (5M+ users, Lionel Messi as ambassador); a $100M+ India job marketplace serving 50M+ users
• Healthcare EMR live in 10+ US states, 15M+ patient charts

• Discovery Sprint available testable artifact in 5–10 days, 100% credited toward Phase 1 if you continue
• I audit before I quote if v1 was built in Replit / Bubble / no-code, or a previous team left a codebase that won't extend, I'll read the code first and quote second
▸ WHO I BUILD FOR
→ Founders pre-launch (AI / mobile / web MVP in 8–14 weeks)
→ Seed-stage teams scaling to 50K–500K users
→ Growth-stage SaaS products adding AI or commissioning a senior engineering audit before their next round
→ Enterprises needing a long-term, one-stop build partner with ISO 27001 controls and HIPAA-aware delivery.

If you're a founder or startup, you've probably hit at least one of these:
→ You need AI features that actually work — not a ChatGPT wrapper.
→ Your app is live, but installs are flat and you don't know why.
→ Your subscriptions aren't converting — high churn, low trial starts.
→ You have no idea where your users come from or where they drop off.
→ A developer handed you code that worked in testing and broke in production.
That's exactly what I fix — from the first line of code to thousands of installs.
