Build, extend, or scale your development team with experienced engineering talent. I help startups, agencies, and growing companies build products, extend existing teams, and deliver complex software with 7+ years across Full Stack, Python, React, AI, and cloud engineering.
Currently
Senior Full Stack Engineer & Technical Coordinator — remote worldwide
Stack running in production
I can work with you in whichever way fits your product and team — as a single senior engineer, an extension of your team, or a fully managed engineering function.
Join an existing engineering team and contribute directly.
Add experienced developers where the current team has capacity gaps.
Build a team specifically around the client's product.
The engineering team handles development, delivery, and technical execution.
Own architecture, development decisions, code quality, and engineering coordination.
Provide continuous development, maintenance, optimization, and scaling.
How engagements typically grow
I build enterprise-ready SaaS and web applications from concept to cloud release. Complete with secure authentication, multi-tenant databases, subscription billing, interactive dashboards, and high-performance REST APIs.
Engineered real-time systems capable of handling thousands of simultaneous WebSocket connections. Ideal for live multiplayer gaming, interactive quizzes, financial tickers, and collaborative dashboards.
Specialized in building high-scale educational platforms (like Banking Quest). Includes course management, online video streams, automated grading, certification issuance, and student progress analytics.
Built custom digital platforms for major publishing brands Allen & Unwin and Murdoch Books. Advanced search, multi-category catalogs, seamless cart checkouts, and internal publishing workflow sync.
Turn your startup idea into a production-deployed, revenue-ready product. I handle backend API setup, database modeling, frontend UI build, authentication, and AWS deployment.
Robust API foundations built to support web apps, mobile clients, and third-party integrations. Clean OpenAPI/Swagger documentation, JWT/OAuth2 authentication, rate limiting, and database query optimization.
Zero-downtime server setups and continuous deployment. I configure EC2 instances, Dockerized services, SSL certificates, Nginx web servers, and GitHub Actions for automated releases.
Eliminate slow SQL queries, memory leaks, and server bottlenecks. I optimize Django ORM calls, implement Redis caching, tune PostgreSQL indexes, and improve frontend loading times.
Transform your platform with custom AI systems. I build RAG document query tools, automated content generators, intelligent customer support agents, and workflow bots powered by LangChain, OpenAI, and Google Gemini.
Keep your web applications secure, fast, and glitch-free. I conduct periodic audits, patch vulnerabilities, upgrade packages, and deliver prompt technical support.

Industries
We've been working with Rayon Web Solutions and Manpreet for over 5 years, and they’ve been an incredible tech partner throughout.
