Most automation projects do not fail because someone cannot write code. They fail because the workflow is messy, the scraper breaks, the API is unstable, the AI output is unreliable, or the backend was never designed to handle real edge cases. That is the kind of work I build and fix. I am a Python and JavaScript backend automation engineer with 5+ years of experience building AI automation systems, web scrapers, REST APIs, bots, backend tools, and data workflows. My main strength is backend automation. I work on systems where data needs to be collected, cleaned, processed, connected to APIs, pushed into databases, sent to bots, or used inside AI workflows. I can help you with: AI agents and automation workflows using OpenAI, Claude, DeepSeek, Grok, Qwen, Ollama, and custom tools. Advanced web scraping with Playwright, SeleniumBase, Puppeteer, Scrapy, curl_cffi, proxies, sessions, CAPTCHA handling, and anti bot bypass. Backend development with Python, FastAPI, Node.js, Express, REST APIs, authentication, databases, webhooks, queues, and third party integrations. API automation, custom integrations, dashboards, admin tools, Telegram bots, Discord bots, and workflow automation. Data pipelines that export to CSV, JSON, Excel, Google Sheets, PostgreSQL, MySQL, MongoDB, Redis, or custom formats. Deployment and server setup with Docker, Nginx, Linux, Hetzner, AWS, DigitalOcean, CyberPanel, AAPanel, and Proxmox. I do not like fragile scripts that only work once. When I build something, I care about clean structure, retries, logs, error handling, rate limits, proxy and session handling, database design, and making the system easy to run after delivery. I have also built real products outside client work. ShieldProxy.cc gave me practical experience with proxies, IP rotation, networking, and scraping infrastructure. DockLift.dev gave me hands on experience with Docker, containers, server management, and deployment workflows. I am also learning Rust because I care about memory safety, performance, and building more reliable backend tools. I do not sell myself as a Rust expert yet, but I like adding stronger engineering habits into the systems I build. My usual process is simple. First, I understand the workflow and identify the risky parts. Then I test the target, API, or automation flow and prove the approach with a small working sample. After that, I build the full system with clean backend logic, proper error handling, logging, exports, and deployment support if needed. If the project needs AI, I do not just connect an API and hope it works. I design the flow around prompts, tools, validation, fallback logic, memory, and human review where needed. The projects I am best for: You need an AI agent that performs real tasks. You want to automate a manual workflow. Your current scraper keeps breaking. A website blocks normal scraping. You need a backend API or automation system. You need data collected, cleaned, processed with AI, and delivered somewhere useful. You need Telegram, Discord, Zapier, Make, n8n, WordPress, or custom API automation. You need someone who understands scraping, AI automation, backend APIs, deployment, and real world failure handling. Send me the website, API, workflow, or idea you want to automate. I can usually tell you quickly what is possible, what is risky, and the cleanest way to build it.

I build and stabilize AI-native SaaS products with Claude Code, Cursor, Next.js, Supabase, RAG, and agent workflows. If you have a half-built AI product, messy Claude/Cursor-generated code, a Supabase app with weak RLS, or a founder-led SaaS that needs production features shipped fast, I can help you move from prototype to reliable production. My strongest work is at the intersection of full-stack engineering and AI systems: - Next.js 15 App Router, React, TypeScript, Tailwind, shadcn/ui - Supabase, Postgres, RLS, Auth, Edge Functions, pgvector - Stripe, Vercel, Railway, Netlify, GitHub, CI/CD, Sentry, PostHog - Claude, OpenAI, Gemini, Grok, DeepSeek, Ollama, vLLM - RAG pipelines, vector search, document ingestion, evals, guardrails - AI agents, tool calling, MCP servers, OpenAPI actions, workflow automation - Slack, WhatsApp, Telegram, Gmail, Google Sheets, Notion, Airtable, n8n I use Claude Code, Cursor, and Codex as serious engineering tools, not just autocomplete. That means maintaining project context, writing clear specs, reviewing generated code, testing edge cases, and turning AI-assisted work into clean commits and production-ready PRs. Common projects I can own end-to-end: - Add an AI assistant or chatbot to an existing SaaS - Build a RAG system over PDFs, websites, internal docs, or product data - Set up Supabase Auth, Postgres schemas, RLS policies, and user dashboards - Stabilize a Next.js/Supabase app with Stripe, Vercel, and production monitoring - Audit and refactor Claude Code or Cursor-generated code before production - Build internal AI tools for founders, operators, sales teams, and support teams - Create Slack, WhatsApp, Telegram, or email automations powered by LLMs - Design AI-native development workflows using CLAUDE.md, MCP, agents, and PR discipline I communicate clearly, work async, and can overlap 4+ hours with US Eastern time from IST. I am comfortable taking vague founder requirements, turning them into a practical technical plan, pushing back when needed, and shipping the version that should actually exist. If your goal is to ship an AI feature, harden an MVP, clean up an AI-generated codebase, or build a reliable agent/RAG workflow, I can step in and own the technical execution.

$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.
