If you need a backend engineer to build, fix, extend, integrate, or improve a production application, I can help with Python, FastAPI, Node.js, TypeScript, Laravel, and PHP — from backend architecture and APIs to SaaS systems, data scraping, data engineering, data analysis, third-party integrations, automations, and AI-powered features. I’m a Senior Software Engineer with 5+ years of experience building and maintaining production web applications, backend systems, SaaS platforms, APIs, database-driven applications, data workflows, and business automations. I focus on reliable architecture, clean code, practical solutions, and software that is built to work in real-world production environments. ### BACKEND & SAAS DEVELOPMENT My core backend stack includes: • Python & FastAPI • Node.js & Express.js • TypeScript & JavaScript • Laravel & PHP • REST APIs and backend services • SaaS and multi-tenant applications • MySQL, PostgreSQL, MongoDB & Supabase • Authentication, business logic, automation & background processes • Third-party API integrations and webhooks Whether you need a new backend, an existing application extended, or a difficult production issue fixed, I can work across the system from architecture to implementation. ### DATA SCRAPING, ANALYSIS & ENGINEERING I also work with data-intensive applications where the challenge is not just collecting data, but turning raw data into structured, reliable, and useful information. I can help with: • Web and data scraping • Python-based scraping and automation • Dynamic website scraping • Data extraction and normalization • Data cleaning and transformation • Data pipelines and processing workflows • Data engineering and database design • Large-scale data processing • Data analysis and exploration • Extracting meaningful insights from raw data • Data aggregation and reporting • Connecting scraped data with APIs, databases, and SaaS applications • Automating recurring data collection and processing My approach is to build the complete data workflow: collect the right data, clean and structure it, store it reliably, process and analyze it, and turn it into meaningful insights that can support real business or product decisions. ### API & THIRD-PARTY INTEGRATIONS A significant part of my work involves connecting applications, APIs, databases, and external services into reliable business workflows. I can help with: • REST API development and integration • Python/FastAPI backend development • Node.js API development • Third-party API integrations • Webhooks and event-driven systems • Social media and business APIs • Data synchronization between systems • Backend automation • API debugging and troubleshooting • Existing SaaS integrations and feature development ### AI, LLM & AI AGENT INTEGRATIONS I also develop and integrate AI capabilities into existing applications, SaaS products, and business workflows. My AI development work includes: • AI API integrations • LLM integrations • AI-powered SaaS features • AI agents and agent-based workflows • AI automation • Structured data extraction using AI • Data analysis using AI • Connecting AI models with APIs, databases, and existing business logic • Integrating AI into Python, FastAPI, Node.js, TypeScript, Laravel, and PHP applications My approach to AI development is practical: I focus on integrating AI into useful production workflows rather than building AI demos that don't solve a real business problem. ### FULL-STACK CAPABILITY While backend development is my primary focus, I can also work with React and Next.js when frontend changes are required to complete a feature or integrate with a backend system. This allows me to handle backend/frontend communication, APIs, authentication, data flows, and integrations without unnecessary handoffs. ### WHAT I CAN HELP YOU BUILD • Python & FastAPI backend systems • SaaS platforms and backend systems • REST APIs and integrations • Node.js & TypeScript applications • Laravel & PHP applications • Web and data scraping systems • Data pipelines and engineering workflows • Data analysis and insight extraction • Data-driven applications • AI-powered applications • AI agents and automation workflows • LLM integrations • Database-driven applications • Third-party API integrations • Backend improvements and bug fixing • Existing application modernization and feature development If you need a reliable backend engineer to build, extend, integrate, or troubleshoot your application—or if you need to collect, process, analyze, and turn data into meaningful insights—I can help build the complete solution from backend infrastructure to production workflows.
