$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.

I’m a QA Engineer and Data Analyst with 3+ years of experience in testing, data visualization, and process optimization. Skilled in manual testing, API testing (expanding into automation with Selenium), as well as Python, SQL, Power BI, and Excel. I’ve delivered projects across industries, including e-commerce, fraud detection, and supply chain, both as a freelancer on Upwork and in corporate roles. Passionate about quality, data-driven decisions, and continuous learning — and open to new freelance opportunities.

I’m a Senior Backend & Cloud Engineer with a strong infrastructure background, specializing in scalable APIs, distributed systems, and production-grade cloud architecture. I started my career building customer-facing backend systems in PHP (Symfony), React applications, and Chrome extensions, while maintaining the Linux servers running them. I then progressed into a dedicated DevOps role where I operated as the sole infrastructure engineer, managing large bare-metal environments, multi-node Elasticsearch clusters (up to 70 nodes), multiple 20+ node Kubernetes clusters, MongoDB databases, and full monitoring stacks. Today, I design and maintain cloud-native backend systems across AWS and GCP, building high-performance APIs in Go and operating Kubernetes environments (EKS/GKE), IoT integrations, event-driven systems, and secure VPC architectures. What sets me apart is full-stack ownership — from application code to networking, infrastructure, observability, and production reliability. I’m comfortable operating at scale, working autonomously, and making architectural decisions that balance performance, cost, and long-term maintainability. If you’re looking for someone who understands both code and infrastructure deeply — and can take responsibility for systems end-to-end — I can help.

If your team is copying data between tools, chasing information across apps, or spending hours on work that should take minutes - you're not alone. I help growing teams eliminate the manual work that's blocking their growth. I build automation systems using Make.com, n8n, and custom integrations that connect your tools and eliminate repetitive work. Whether it's CRM chaos, manual onboarding processes, or reporting nightmares, I design systems that just work. 🚀 RECENT PROJECTS: 🔹 CRM Automation for Nonprofit - Built Google Sheets + SendGrid system managing 11-agent workflow, eliminating manual email tracking and data entry. Enabled real-time visibility and automated follow-ups. 🔹 WordPress Form Processing - Automated form submission handling, validation, and data routing across multiple systems. Removed hours of weekly manual data entry and eliminated copying errors. 🔹 Data Extraction System - Created automated system processing 45,000+ exam records with complex validation rules. Transformed weeks of manual work into hours of automated processing. 🎯 COMMON PROBLEMS I SOLVE: 🔹 Sales & CRM Chaos - Your lead data lives in 5 different places. Sales reps manually copy information between tools. Deals fall through cracks because follow-ups are forgotten. I build automated lead capture and routing, unified CRM sync, automated follow-up sequences, and deal stage tracking with notifications. 🔹 Customer Onboarding Bottlenecks - New customers wait days for setup while your team manually creates accounts, sends emails, and provisions access. Each onboarding follows a different process. I build automated customer provisioning, welcome sequence triggers, account setup workflows, and progress tracking dashboards. 🔹 Reporting Time Sink - Your team spends 10+ hours monthly compiling reports by manually copying data from multiple tools into spreadsheets. By the time reports are done, they're outdated. I build automated data collection, real-time dashboards, scheduled report generation, and customized views for different stakeholders. 🔹 Integration Gaps - Your tools don't talk to each other. Customer support tickets live separately from your CRM. Invoicing requires manually copying data from 3 sources. I build two-way API integrations, automated data synchronization, centralized data workflows, and custom middleware when needed. 🔹 Manual Quality Control Issues - Human errors in repetitive processes damage customer relationships. Data entry mistakes create downstream problems. Inconsistent processes mean different team members handle things differently. I build validation systems, error checking workflows, standardized process automation, and audit trails for compliance. 💡 WHY COMPANIES WORK WITH ME: 🔹 I Redesign, Not Just Automate - Most consultants take your existing process and speed it up 2x. I look for opportunities to redesign workflows from scratch, often finding 10x improvements. Sometimes the answer isn't automation at all, it's changing how you approach the problem. 🔹 I Speak Both Technical and Business - With 15 years of software engineering experience at startups and enterprises, I can build custom solutions when your needs outgrow simple tools. But I excel at explaining technical concepts in business terms and focusing on ROI, not just technical elegance. 🔹 I Can Go Custom When Needed - Most projects work great with Make.com or n8n. But when you hit edge cases - complex data transformations, custom API endpoints, legacy system integration - I can write actual code. This flexibility means you're not boxed in by tool limitations. 🛠️ WHAT I BUILD WITH: 🔹 Primary Tools: Make.com, n8n, Zapier 🔹 Integration Specialties: CRMs (HubSpot, Salesforce, Pipedrive, Close), Marketing (SendGrid, Mailchimp, ActiveCampaign), Databases (Google Sheets, Airtable, PostgreSQL, MySQL), Forms (WordPress, Typeform, Google Forms), Communication (Slack, Teams, SMS via Twilio), Custom APIs and webhooks 🔹 Technical Capabilities: RESTful API integration and authentication (OAuth, API keys), data transformation and validation logic, error handling and notification systems, database design for scalable workflows, custom code when automation tools hit limits (JavaScript, Python, Ruby) 👥 WHO I WORK BEST WITH: 🔹 Growing companies (10-100 employees) hitting process scaling walls 🔹 Teams spending 10+ hours/week on repetitive manual work 🔹 Businesses with data scattered across 3+ tools 🔹 Companies ready to invest in operational efficiency Message me with your biggest manual work headache. I offer a free 15-minute consultation where I'll tell you honestly whether automation can solve your specific problem, what approach would work best, rough timeline and investment needed, and if I'm not the right fit, I'll tell you that too. No obligation. Just clear answers.
