I build scalable web and database applications, by performing customizations, upgrade package development, versioning, application provisioning, performance monitoring and report development. I follow best practices and code standards for quality assurance, by building secure applications with logging system, monitoring, data validation, error handling, concurrency and performance optimization. I use front-end technologies like Bootstrap, JQuery, JavaScript, AngularJs, C# Razor, ASP.NET MVC to build responsive web design and enhanced user experience. I use back-end technologies like ASP.NET Core, C#, Automapper, Entity Framework, Dapper, NodeJs, Node-Red to build Restful Web API, data integrations and background scheduled jobs. I use database technologies like SQL Server, Transact-SQL, Redgate, Oracle, PL-SQL to build relational model satisfying data integrity and consistency, write database routines, evaluate indexes, performance, query tuning and monitoring. I use a variety of tools like Jira, Github, Bitbucket for application lifecycle management, source control repository and project management. I also develop containerized cloud-based solutions using AWS, Azure and Docker. I have a bachelor’s degree and a master’s degree in Computer Science, focused on data science and machine learning algorithms. I have developed a new technique to solve multi-dimensional clustering problems and I have published an article. I have focus on client requirements, prioritization and deadlines, working on a collaborative remote environment with distributed teams. I have the motivation to learn anything required to deliver the project in which I work.

I build Python backend systems that hold up as they grow — designed properly from the start, so you're not rebuilding them a year later when traffic or features outpace the original setup. Most backend problems aren't really about writing code. They come from decisions made early that get expensive later. I focus on getting those right: how the system is structured, how the data is modeled, where the bottlenecks will show up, and what to build now versus what to leave room for. That judgment is what separates a system that scales from one that gets rewritten. What I do: Backend & APIs — FastAPI and Django REST, built for real traffic. Versioned, well-structured APIs with proper error handling, pagination, and idempotency — not just happy-path code. Architecture & scale — Multi-tenant SaaS systems with tenant isolation and role-based access. Structuring services and data flow so the system stays maintainable as it grows, not just on day one. Data layer — PostgreSQL schema design, indexing, query optimization, and migrations without downtime. Redis for caching and queues. Async & background work — Celery, event-driven workflows, webhook handling, and retries — the parts that need to keep working when external services don't. Taking it to production — I deploy what I build: Docker, AWS/GCP, CI/CD, and monitoring. I own the system end to end, so nothing gets handed over half-finished. When a system needs it, I also cover automation — n8n, Make, Zapier, or custom Python scripts — along with payment and third-party API integrations, so you get a complete build rather than parts to stitch together. Why hire me: 70+ completed projects, $80K+ earned on Upwork, 5,500+ hours, and consistent 5-star reviews. Recent work includes a recruitment platform handling 50K+ requests/day, a multi-service exam platform, and multi-tenant SaaS systems running in production. The code is clean, documented, and maintainable, and I deliver on time. If you need a senior engineer to build a backend that stays reliable long after launch — and to make the right calls while building it — message me. Tech: Python, FastAPI, Django, PostgreSQL, Redis, Celery, Docker, AWS, GCP

I help founders, startups, and growing businesses turn ideas into production-ready SaaS products, MVPs, dashboards, and scalable web applications. Most clients come to me when they need more than just coding. They need someone who can help plan the product, build the right features first, launch quickly, and create a stable technical foundation that supports real users, payments, admin workflows, automation, and future growth. Over the last 6+ years, I’ve worked across the full stack using React, Next.js, Node.js, Express.js, MongoDB, PostgreSQL, TypeScript, REST APIs, authentication systems, payment integrations, and cloud deployments. What I build: • SaaS Platforms • MVP Development • AI-Powered Web Apps • Admin Dashboards • Customer Portals • Subscription Systems • Internal Business Tools • API Integrations • Automation Workflows • Scalable Backend Systems I also specialize in fixing and scaling AI-generated or vibe-coded applications built with tools like Lovable, Bolt, Cursor, Replit, Same.dev, and v0. Many founders quickly discover these tools can generate UI fast — but production stability, architecture, scalability, authentication, payments, security, and maintainability still require an experienced engineer. I help transform those prototypes into clean, scalable, production-ready applications. Recent Project: I helped Alpha Security, a Netherlands-based security company, replace manual spreadsheets and paper-based operations with a custom internal platform. The system included: • Security pass applications • Job vacancy management • KPI tracking • Customer review management • Workflow automation This reduced manual operational work by 3+ hours per day and streamlined the company’s daily processes. My approach is business-focused, not just code-focused. Before development starts, I help identify: • What should be built first • Which features can wait • How to reduce unnecessary complexity • How to launch faster • How to structure the product for scaling When the project is complete, you receive: • Clean, maintainable code • Production-ready deployment • Organized project structure • API integrations • Technical documentation • Proper handover support I also provide long-term support for live products, including: • Bug fixing • Performance optimization • New feature development • Deployment support • Refactoring • Technical cleanup • Scaling improvements Tech Stack: React.js • Next.js • Node.js • Express.js • TypeScript • JavaScript • MongoDB • PostgreSQL • Tailwind CSS • REST APIs • Stripe • Authentication • Vercel • Netlify • AWS • Docker • Supabase If you’re building a SaaS product, MVP, startup platform, customer portal, AI-generated prototype, or internal business system, send me a message and I’ll help you find the fastest practical path to launch.

You're probably wondering, among thousands of Top Rated Plus freelancers, what makes this one any different. And honestly? Skill-wise, not much. Every Top Rated Plus developer on this platform is in the top 3% of Upwork. We've all shipped production-grade products, debugged at 2am, and argued about the right way to structure a database schema. That's just the baseline. Where I'm different is how I show up. I don't take a brief and disappear into a code editor. I ask questions. I challenge assumptions. I push back when something doesn't make business sense, and I'll tell you when a simpler solution beats the one you came in with. I've built and run my own SaaS products, and I come from a business background, so I see every project through two lenses at once: what you're building technically, and whether it's actually going to work as a business. Most developers will build exactly what you ask for. I'll build what you actually need. That means you get a co-builder, not a contractor, someone who's genuinely invested in the outcome, brings a bit of humor to the process, and won't let you spend six figures heading in the wrong direction. If that's the kind of working relationship you've been looking for, keep reading. My core stack: React / Next.js, Node.js, TypeScript, Supabase / PostgreSQL, MySql MongoDB, Mongoose, Prisma, Rest API, GraphQL AI Integrations: OpenAI, Claude, Open Router, Grok, Gemini, Perplexity, Eleven Labs, Vapi, and AI Agents Automation: n8n, make, and zapier. 🌟 Here's what founders I've built for are actually saying: ● "Since the new platform launch, our online sales have skyrocketed by 300%!" ● "Customer sign-ups and engagement magnified after the rebuild!" ● "Seamless app and e-commerce integration, our revenue grew by over $2M!" ● "Our redesigned product won the Web Excellence Award for best UI/UX!" 10+ years of full-stack development. $10M+ in client revenue powered by platforms I've shipped: SaaS products, web apps, e-commerce engines, real estate portals, and AI-powered platforms across B2B and B2C. *** ⚡ We're probably a great fit if you're thinking: ● "I have a huge market opportunity and need the best engineer to capture it" ● "My product vision has grown, but the codebase hasn't caught up" ● "I know the business side, I need a technical co-builder I can actually trust" ● "I'm not a developer and can't afford to waste months on the wrong hire" ● "My last dev burned me badly, I won't let that happen again" ● "I need a scalable, production-grade platform built to grow with me" *** What you get when we work together: ★ Full ownership: Architecture, Frontend, Backend, APIs, Deployment, and Product Strategy, handled ★ A production-ready platform your users love and your investors respect ★ Technical debt and architectural mistakes caught before they become expensive ★ A turnkey, scalable codebase built to survive your next funding round ★ Clear communication, on-budget delivery, and no surprises mid-project ★ Core architecture you can reuse across future product lines, cutting long-term dev costs significantly *** What my clients say: ✅ "Saimul does incredible work! Super passionate, consistently went above and beyond every single time." ✅ "Communication was always smooth, very proactive and easy to reach throughout the entire project." ✅ "Highly solution-oriented with deep skills across his field, a genuine problem solver." ✅ "Great listener who translates complex requirements into a product that actually works." ✅ "Excellent work, sharp attention to detail, and always willing to go the extra mile for the team." *** I specialize in serious product builds, SaaS MVPs, B2B platforms, AI integrations, e-commerce systems, and complex full-stack applications. No template flips. No shortcuts. I've shipped 150+ websites and web apps across a decade of development. As an engineer and technical architect, I have a 360° view of the full build lifecycle, from discovery and wireframing through production deployment and post-launch optimization. My capacity is limited. I carry 80% repeat clients and 40% referrals, and I only take on projects I'm certain I can execute at the highest level. What I look for in a new client: ● A clear product vision with room to collaborate ● Values clean architecture and long-term thinking over shortcuts ● Focused on real user outcomes, not just shipping pixels ● Knows the scale they're building toward Not the right fit if: ✗ You need a $300 template site, that's not what I build ✗ You want to micromanage architecture decisions and sprint cycles ✗ Honest communication and mutual respect aren't priorities *** Sound like a fit? 📋 Review my portfolio and live project examples on this profile 💬 Hit "Invite" or "Message" and send me a short note about your project, I respond within hours.
