I'm Sheharyar, a senior full stack engineer. I help businesses and startups turn an idea into a product that's fast, reliable, and built to hold up as it grows, and I take ownership of the technical side so you don't have to manage it. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 𝗼𝗻 𝗮 𝗽𝗿𝗼𝗷𝗲𝗰𝘁: I start with the questions most developers skip: what does this actually need to do, where will it have to scale, and what's the simplest architecture that gets you there without painting you into a corner. Then I build it, front to back, and I'm straight with you about trade-offs along the way instead of just saying yes to everything. 𝗪𝗵𝗮𝘁 𝘁𝗵𝗮𝘁 𝗹𝗼𝗼𝗸𝘀 𝗹𝗶𝗸𝗲 𝗶𝗻 𝗽𝗿𝗮𝗰𝘁𝗶𝗰𝗲: - 𝗙𝗿𝗼𝗻𝘁𝗲𝗻𝗱 𝘁𝗵𝗮𝘁 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝘀. React, Next.js, Vue, and Angular, built responsive and fast, because a slow interface costs you users no matter how good the backend is. - 𝗕𝗮𝗰𝗸𝗲𝗻𝗱 𝗯𝘂𝗶𝗹𝘁 𝘁𝗼 𝗹𝗮𝘀𝘁. Secure, well-structured APIs and server logic in Node.js, Express, NestJS, and Python (Django, FastAPI), designed so the system stays clean as it grows instead of turning into something nobody wants to touch. - 𝗔𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲 𝗮𝗻𝗱 𝗶𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 𝘁𝗵𝗮𝘁 𝘀𝗰𝗮𝗹𝗲 𝗼𝗻 𝗽𝘂𝗿𝗽𝗼𝘀𝗲. Databases (MongoDB, PostgreSQL, MySQL) tuned for real performance, and deployment on AWS, GCP, Docker, and Kubernetes set up to scale smoothly, not patched together under pressure. - 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀 𝘁𝗵𝗮𝘁 𝗷𝘂𝘀𝘁 𝘄𝗼𝗿𝗸. Payment gateways, authentication, headless CMS, third-party APIs, wired in cleanly so they hold up in production. 𝗪𝗵𝗮𝘁 𝘄𝗼𝗿𝗸𝗶𝗻𝗴 𝘄𝗶𝘁𝗵 𝗺𝗲 𝗶𝘀 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗹𝗶𝗸𝗲: You get someone who owns the outcome, not just the tasks. I communicate clearly and on a schedule, I flag risks early instead of at the deadline, and I tell you when something is a bad idea, even when it's easier to nod. The 100% Job Success and Top Rated Plus on this profile come from delivering that consistently, not from taking every job that comes along. If you've got something important that needs to be built right the first time, and you'd rather hand the technical side to someone who'll think about your business and not just your ticket list, send me a message. Tell me what you're building and I'll tell you honestly how I'd approach it.

I help startups go from idea to live product. With 4+ years building full-stack web apps and AI-assisted development workflows using Claude and Cursor, I consistently deliver in days what used to take weeks. My clients get working products, not just code. I've shipped real products across travel tech, fintech, and SaaS including a two-sided travel marketplace and a full hotel management ecosystem with 5 integrated products, and MVPs deployed live on Vercel, Render, and Neon. What I build: → SaaS platforms & internal tools (Vue/Nuxt, Golang, Supabase) → AI-powered features & workflow automation → MVPs that are production-ready from day one → Dashboards, admin panels & real-time apps I don't just execute tickets. I think about architecture, user experience, and long-term maintainability then ship it quickly. If you need someone who takes ownership and delivers, let's talk.

I provide a Node.js Backend Developer team that ships production-grade SaaS, APIs and platforms. 11,000+ hours worked, 50+ Node.js Backend Developer projects delivered, 100% Job Success Score, Top Rated Plus. As CEO I scope and own every Node.js Backend Developer engagement we sign. I study the brief, run discovery with founders, match the right engineers and stay accountable for delivery. My team owns the code - I never touch it. So when a brief lands for a Backend Engineer, an API Developer or a full stack software engineer, I scope it and the team builds it. Why hire my team: - 20+ years of Node.js Backend Developer, Full Stack Developer and SaaS Developer delivery - 200+ Node.js Backend Developer and SaaS Developer projects shipped - Long-term clients on retainers (3 - 10+ years) Our Node.js Backend Developer team designs services, REST and GraphQL APIs, queues and event pipelines that hold up under real production load. A NestJS Developer on the team treats Node as a serious production runtime and owns the heavy backend modules. Typical engagements: multi-tenant SaaS APIs, real-time platforms, billing flows, data pipelines, AI-backed services. Stack: Node.js, NestJS, ExpressJS, TypeScript, PostgreSQL, Redis, Elasticsearch, AWS, GCP, Docker, Kubernetes. Our Full Stack Developer team owns systems end-to-end - one team handling Node.js services, React frontends, data models and infra. A React Node pairing is our default shape - a React Node frontend on a NestJS Developer backend, with a nextjs developer on SEO-critical pages. We replace fragmented setups where a website developer, web developer and front end specialist were stitched together. Adjacent angles I present daily: full stack developer saas for B2B platforms, python full stack developer pairings for data and AI, full stack developer ai integrations, full stack developer react teams for SaaS dashboards, full stack developer shopify extensions, full stack web developer rebuilds of legacy SPAs, full stack ai saas developer engagements where LLM features must ship at production standard. Our SaaS Developer team helps founders ship multi-tenant SaaS and B2B platforms. A SaaS Developer engagement covers auth and RBAC, Stripe billing, observability, anti-abuse and event tracking the saas marketing team can use. The team has shipped a webflow developer saas pairing, a b2b saas booking system developer engagement, a ui ux designer saas pipeline, a saas explainer video flow in onboarding and a saas sales console wired into the backend. On the API side a dedicated API Developer track owns contracts and versioning. A REST API Developer designs the REST API Developer surface - resources, pagination, idempotency, webhooks - and the API Developer keeps SDKs and docs honest. A Backend Engineer owns the data layer; a second Backend Engineer covers queues and workers so the API never blocks on jobs. Cross-language coverage. A python developer track owns scraping, ETL and AI workflows. python nodejs migrations land here when teams consolidate dual stacks. flutter node.js and vue.js node.js setups join the core when mobile or admin SPAs need a reactive layer. A react developer pairing handles SaaS dashboards on the API. A wordpress developer or shopify developer hand-off covers CMS migrations. A mobile app developer pairing extends the SaaS into iOS and Android. Clients hire me when they need: - a Node.js Backend Developer team that owns architecture, APIs and scaling - a back end developer node.js bench for high-traffic SaaS - a Full Stack Developer team replacing 3 - 5 contractors with one coherent system - a SaaS Developer team fluent in multi-tenancy, auth, billing and RBAC - an API Developer and Backend Engineer pair for a clean, versioned REST API Developer surface - a full stack software developer practice with CEO-level discipline on roadmaps - a website developer hand-off backed by the team Recent work my team shipped: - Cybersecurity SaaS. Node.js, NestJS, PostgreSQL, Redis on GCP + Kubernetes. 170M+ req/week, 500 RPS peaks, 1M+ MAU. - Device Verification SaaS. Single backend powering web, Telegram bot and Developer API. 4K+ DAU, 1M+ checks, 80%+ via API. - Clinic Enterprise platform. React, Next.js, Laravel, Node.js, Redis, AWS. REST API, queues, RBAC, 1C and lab integrations. MVP in 4 months for 500 patients/day, 500K records. - E-commerce Data Pipeline SaaS. 50M+ products, per-partner parsers, dedup. Cloud cost cut ~9x at sub-second search across 300 - 500K DAU. - Multi-currency Voting SaaS. Wallets, Stripe top-ups, real-time vote locking over WebSockets. 2M+ users in 10 countries, $2.5M+ revenue. Reliable SaaS comes from deliberate design - that's what my Node.js Backend Developer, Full Stack Developer and SaaS Developer team focuses on. Need a Node.js Backend Developer team, a Full Stack Developer team or a SaaS Developer partner that delivers on time and stays long-term - let's talk.
