Most business software is either too expensive, too rigid, or just doesn’t match how you actually work. I build custom systems that automate processes, reduce manual work, and scale with your business - exactly the way you need. 🚀 Many businesses rely on expensive, off-the-shelf software that doesn’t fit their real processes - or forces them to pay for features they don’t need. I design and build custom systems that: • match your actual workflows instead of forcing you to adapt • automate manual processes, saving time and reducing errors • integrate with your existing tools seamlessly • stay flexible as your business grows What I deliver: • Custom business systems replacing or complementing legacy platforms • Process automation and workflow digitization • CRM/POS integrations and data synchronization • Scalable, maintainable architecture (.NET, React, Angular, MS SQL, MongoDB, Node.js) How I work: I start by understanding your operations and pain points, then design a solution that eliminates inefficiencies and unlocks growth potential - without overpaying for unnecessary complexity. If you’re paying too much for software that doesn’t really fit your business, I can help you build something better.

If you're building a React or Next.js app — and need it to be fast, well-structured, and optionally AI-powered — I can help. I've spent 7+ years building frontend applications for startups and product teams. My focus is React and Next.js, but what separates me from most frontend developers is the AI layer: I build the UIs that make AI products actually usable — streaming chat interfaces, tool-call displays, markdown rendering, conversation history, and LLM API integration (OpenAI, Anthropic, Gemini). What I build: → React / Next.js apps — MVPs to production, with TypeScript and Tailwind → AI chat frontends — streaming text, tool-call UIs, markdown rendering → LLM API integration — OpenAI, Anthropic Claude, Gemini wired into your app → Workflow automation — n8n, Zapier, Airtable connected to your product → Full stack when needed — Node.js, Python (FastAPI/Flask), REST, GraphQL → Data dashboards — analytics UIs with real-time data and clean design I work well with founders building AI products, agencies needing a reliable senior dev, and product teams who need someone who understands both code and user experience. Available for short tasks and long-term contracts. Message me with your project and I'll give you an honest assessment.

My main areas of expertise: -Node JS -Typescript-Javascript -Svelte -Vue -C# -.NET My software life: In 2011, I wrote my first Hello world program for Symbian in C++ QT. The old age of Symbian and the rise of android and ios pushed me to make applications for android and ios and I searched for a new language. The functionality of Adobe Flash program and being able to write programs for any platform with actionscript convinced me to learn actionscript 3.0. For about 2 years, I wrote various programs and made applications for android, windows and ios with actionscript. However, as it was the end of everything, with the development of Javascript, the end of Adobe Flash was now visible. I searched for languages ​​again for my projects. I was very interested in the increase in popularity of .Net with C# 5.0 for Windows, and the fact that C# is an object-oriented programming made it easy. At the same time, I learned asp.net and started to develop applications for the web. Asp.net's adoption of MVC provided easy manageability for large-scale applications. For my Android apps, I started learning Java, which is similar in some ways to C#. Today I still use C# for windows and Java for android. However, switching to my own servers and using linux on my own servers was causing me to use asp.net. At that time .netCore was new and had a lot of shortcomings. I've been looking for a new language to develop web applications on my servers. At first, the increasing popularity of python came to my mind, but my habit of using parentheses while writing programs made me very cold from python. Another language growing in popularity was Node.js Javascript. The big change in javascript especially in 2015 increased my interest in javascript and now I have adopted Node.js as the new web application language. Today I still use node.js for web projects. My embedded systems life; I first started embedded systems with Arduino in 2012. In those years, I was learning to program MCUs while working on electricity and electronics. Later, I worked with many mcu from Atmel AVR family and designed PCBs for these mcu's. After Atmel AVR, I switched to ARM architecture. First of all, I started with SAML21 and SAMD21 Cortex M0+ mcus of Atmel company. Then I worked with SAMB11 mcu for Bluetooth. Later, I worked with Nordic company's mcu ls such as nRF52832. I am currently working with the ESP32 microcontroller of the ESP company, which I tried many years ago but missed because it had too many errors at that time, but has overcome these errors when we come to today.

I help businesses turn ideas into working web products. I work across product, design, and engineering: defining the scope, planning user flows, designing the interface, building the frontend and backend, setting up infrastructure, deploying the product, and improving it after launch. My background started with deep website performance work: Core Web Vitals, PageSpeed, WordPress, Shopify, PHP, MySQL, Nginx, Redis, caching, JavaScript, CSS, and mobile optimization. That gave me strong experience debugging real production systems across code, servers, databases, cache layers, and networks. Today I build complete product systems across different domains: SaaS tools, admin dashboards, ecommerce storefronts, Telegram bots, ad platforms, AI chat interfaces, vector search/RAG apps, Cloudflare Workers, automation tools, blockchain/Tron integrations, and deployment-ready full-stack applications. I can help with: - Turning a rough idea into product scope, UX flows, screens, and implementation - Designing practical interfaces for dashboards, tools, marketplaces, bots, and web apps - Building full-stack products with TypeScript, Svelte/SvelteKit, APIs, databases, auth, and integrations - Creating AI features such as chat UIs, document search, vector search, and RAG workflows - Building Cloudflare Workers, edge APIs, Telegram bots, automations, and serverless systems - Setting up production deployment: Docker, VPS, reverse proxies, domains, SSL, CI/CD - Improving performance across frontend, backend, database, cache, hosting, and infrastructure - Debugging hard production issues where the problem may be in product logic, code, server config, database, cache, or network behavior My value is that I can take ownership of the full path from product idea to production system. I do not only implement tickets; I can help shape the product, design the workflow, build the system, ship it safely, and keep improving it.

Need one developer who can own a project end-to-end — frontend, backend, database, and deployment — instead of juggling three specialists and a project manager? That's what I do. I'm a full-stack developer with 7+ years of experience building production web applications across Vue.js, Angular, React, Svelte, and Node.js. I write the frontend, build the API, set up the database, and ship it — one person, one point of contact, faster delivery. A few things that back this up: - Cut build times 70% by migrating a legacy AngularJS application to SvelteKit, while improving long-term maintainability (full-time engineering role). - Spent nearly 3 years on a single Upwork engagement worth $40,900+, working across Vue.js, Angular, React, and Next.js for the same client — they called me "an asset to the team." - A separate client paid $21,262 in fixed-price work over 13 months and said: "I've spent millions through Upwork, worked with many engineers, Pradip is one of the top." - Built RESTful APIs for a production SaaS product and shipped a Google Calendar integration that simplified event management for end users. - Maintained a 100% Job Success Score and 5.0 average rating across 23 completed Upwork projects. How I work: daily progress updates so you're never left guessing, a 0-4 hour average response time, and clean, typed code I'm comfortable defending in a code review. I also use Claude Code in my workflow — it handles boilerplate and repetitive scaffolding, which frees up my time for the architecture decisions and edge cases that actually determine whether your product holds up in production. My stack: Frontend: Vue.js, Angular, React, Svelte/SvelteKit, TypeScript, Tailwind CSS Backend: Node.js (Express, NestJS, Fastify), RESTful API design Data & Cloud: PostgreSQL, MongoDB, Firebase, Docker, AWS, CI/CD Mobile (bonus): Ionic + Capacitor, for shipping the same codebase to iOS and Android Whether you need a full application built from scratch, an existing codebase taken over and stabilized, or backend work to support a frontend team, I can plug in quickly. Send an invite and let's talk about what you're building.
