I am a FULL STACK ENGINEER with strong experience in building scalable, cloud-based applications using ReactJs, NextJs, JavaScript, Python, Ruby, AWS, NodeJS, NestJS, MongoDB, Stripe, Twilio, OpenAI, iElevenLabs and more. Over the past few years, I have led the development of froentend & backend systems for web and mobile apps, including a social media platform MVP where I designed and implemented serverless architecture using AWS Lambda, API Gateway, S3, and DynamoDB. This allowed the platform to scale smoothly and stay cost-effective. My core strength lies in designing RESTful APIs, setting up database structures, and writing clean, efficient code that performs well even under high traffic. I regularly work with MongoDB and have a solid understanding of database design, indexing, and query optimization. I also have hands-on experience in authentication systems, role-based access control, and integrating third-party APIs. I enjoy solving complex problems and making backend systems faster, more secure, and easier to maintain. Iโm comfortable working independently or with cross-functional teams, and I often collaborate with frontend developers to ensure the entire application works smoothly from end to end. While my main focus is backend, I also have experience with React, which helps me understand how backend and frontend connect. If you're looking for someone who can take ownership of the end to end development, set up reliable cloud infrastructure, and deliver robust and well-documented APIs โ Iโd love to help.

9+ years of full-stack engineering experience, with a focus on AI integrations, scalable SaaS architecture, and production system reliability. I help product teams and founders build AI-powered web applications that are stable, maintainable, and ready for real users โ not just demos that work in development. Best fit: LLM integrations, RAG pipelines, AI agent workflows, SaaS backend architecture, real-time systems, RBAC design, and technical rescue work. I work well with clients who need clean API design, reliable backend systems, secure authentication flows, and long-term code maintainability. ------------------------------------------------------------ Core Areas AI and LLM Engineering: RAG pipeline design and optimization, LLM integrations (OpenAI, Claude, Gemini), AI agent workflows, multi-agent orchestration, semantic search, vector databases, prompt engineering, token cost optimization, and production AI debugging. Software Architecture: Multi-tenant SaaS platforms, RBAC and permission systems, event-driven backends, modular monolith and microservice design, API-first architecture, codebase audits, and technical rescue work. Backend Engineering: NodeJs, NestJS, Express, TypeScript, REST APIs, WebSockets, JWT Auth, Queue systems, Serverless functions Frontend Engineering: NextJs, React, TypeScript, Tailwind CSS, Material UI, Server Components, App Router Databases and Storage: MongoDB, PostgreSQL, Redis, Supabase, Firebase, Prisma, Mongoose, Vector databases (Pinecone, pgvector, Qdrant) Cloud and DevOps: AWS Lambda, Docker, CI/CD pipelines, Serverless architecture, Environment management and production deployment ------------------------------------------------------------ Relevant Experience: AI-powered SaaS platforms with LLM features, semantic search, and document processing pipelines built for production workloads. RAG systems with retrieval tuning, chunking strategy, embedding pipelines, and accuracy optimization across real datasets. Multi-agent orchestration workflows using Claude and OpenAI APIs with structured output, fallback handling, and observability.

Real-time applications using SocketIo and WebSockets for live collaboration, notifications, and event-driven features. Full-stack bill management and invoicing platforms built with NextJs, Supabase, and customizable document templates. Serverless backend systems on AWS Lambda with TypeScript, MongoDB, JWT token rotation, and CI/CD integration. RBAC engine design with modular architecture, Drizzle ORM adapters, Auth0 integration, and NestJS API layer. ------------------------------------------------------------ I think like an architect, but I still write the code. I care about clean data flow, proper error handling, security by design, and systems that the next engineer can understand without a guided tour. I do not build fragile prototypes. I build production systems that survive real users and can be maintained after launch. If your project needs an engineer who can understand the product, identify technical risk early, and ship reliable software โ let's talk.

MongoDB Developers Hiring FAQs
What is MongoDB?
MongoDB is a popular NoSQL database for storing data in JavaScript Object Notation (JSON). It was launched in 2009 to give developers an unstructured data-friendly alternative to relational databases such as MySQL that store structured data in columns and rows.
How do you hire a MongoDB developer?
You can source MongoDB talent on Upwork by following these three steps:
- Write a project description. Youโll want to determine your scope of work and the skills and requirements you are looking for in MongoDB developers.
- Post it on Upwork. Once youโve written a project description, post it to Upwork. Simply follow the prompts to help you input the information you collected to scope out your project.
- Shortlist and interview MongoDB developers. Once the proposals start coming in, create a shortlist of the professionals you want to interview.
Of these three steps, your project description is where you will determine your scope of work and the specific type of MongoDB developer you need to complete your project.
How much does it cost to hire a MongoDB developer?
Rates can vary due to many factors, including expertise and experience, location, and market conditions.
- An experienced MongoDB developer may command higher fees but also work faster, have more-specialized areas of expertise, and deliver higher-quality work.
- A contractor who is still in the process of building a client base may price their MongoDB development services more competitively.
Rates typically charged by MongoDB developers on Upwork are:
- Beginner: $20 per hour
- Intermediate: $36 per hour
- Advanced: $120 per hour
Which one is right for you will depend on the specifics of your project.
How do you write a MongoDB developer job post?
Your job post is your chance to describe your project scope, budget, and talent needs. Although you donโt need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if theyโre the right fit for the project.
Job post title
Create a simple title that describes exactly what youโre looking for. The idea is to target the keywords that your ideal candidate is likely to type into a job search bar to find your project. Here are some sample MongoDB developer job post titles:
- Back-end developer needed for a MEAN (MongoDB, Express, Angular, Node.js) project
- Seeking a MongoDB developer experienced with React Redux
- Full-stack developer with Flutter and MongoDB experience
Project description
An effective MongoDB job post should include:
- Scope of work: From database management to RESTful APIs, list all the deliverables youโll need.
- Project length: Your job post should indicate whether this is a smaller or larger project.
- Background: If you prefer experience with certain industries, web technologies, or developer tools, mention this here.
- Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.
MongoDB developer job responsibilities
Here are some examples of MongoDB job responsibilities:
- Configuration and management of MongoDB deployments on premises and in the cloud
- Design, development, and implementation of data architectures
- Assist IT operations with virtualization, DevOps automation, and big data analytics pipelines
MongoDB developer job requirements and qualifications
Be sure to include any requirements and qualifications youโre looking for in MongoDB developers. Here are some examples:
- MongoDB
- Database management
- Big data analytics (e.g., Spark, Hadoop)
- DevOps automation (e.g., Ansible, Puppet)
- Virtualization (e.g., VMware, Kubernetes)
- Cloud technologies (e.g., AWS, Google Cloud Platform, Microsoft Azure)
