Project details
Most freelancers set up a server. I architect one. With 10+ years building production Node.js backends at SaaS companies acquired for $40M+, I deliver code your team can extend, scale, and trust — not rewrite in six months.
I've built Fastify and Express servers powering high-volume data pipelines, CRM integrations, async job queues, and multi-tenant SaaS platforms. I know what breaks at scale and how to avoid it from day one — proper folder structure, middleware architecture, schema validation, centralized error handling, and environment config that doesn't fall apart in production.
Whether you need a lightweight Fastify API for a microservice, a full Express backend with auth and database integration, or a production-ready server with Docker and cloud deployment — I scope it right, build it clean, and hand it off with documentation your team can actually use.
This is for founders and engineering teams who want a backend done properly the first time — by someone who's shipped at scale, not just studied it.

HubSpot Developer – Automate Subscription Creation via API
Abhishek did outstanding work. He implemented a custom HubSpot workflow and API integration for us and delivered everything quickly and exactly as expected. Communication was excellent throughout the project, and he was extremely responsive when questions came up during testing. The solution works perfectly and was delivered on time. Highly recommend and would absolutely work with him again.

Job Success
Bengaluru, India - 8:00 am local time
Now in 2026, I help startups ship production-ready products without the overhead of hiring separate designers, frontend/backend engineers, and DevOps teams.
With 10+ years across UI/UX design, full-stack development, cloud infrastructure, and AI integration, I operate as a true Founding Engineer - someone who can design it in Figma, build it in Next.js/React, deploy it on AWS, and scale it cleanly.
WHAT MAKES ME DIFFERENT
Two Successful Exits - I've worked on core services in SaaS companies that successfully exited. I understand what separates products that merely ship from products that scale and sell: clean architecture, business-aligned engineering decisions, and disciplined prioritization.
Design-First Engineering - I started in UI/UX. I don't approximate designs - I translate Figma into pixel-accurate, performance-optimized interfaces that feel intentional and polished.
Production-Scale Thinking - I build MVPs that don't need expensive rewrites. My systems are structured for scale from day one - proper abstractions, async processing, API integrations, and extensibility.
AI-Ready Architecture - Hands-on experience with conversational AI, chatbots, OCR pipelines, LLM integrations (OpenAI, Gemini, Claude), RAG, AI agents, and workflow automation with n8n.
CORE STACK
Frontend: Next.js, React, TypeScript, Socket IO, Chrome Extensions
Backend: Node.js (Fastify, Express), Python, Kafka, Redis, REST/GraphQL APIs, webhooks
AI/ML: OpenAI API, Claude API, LangChain, AI agents, RAG, embeddings, OCR (Tesseract, Textract, Google Vision)
Automation: n8n, Apache NiFi, CRM integrations (HubSpot, Salesforce, Airtable)
Databases: PostgreSQL, MySQL, MongoDB, Redis
Design: Figma, Motion UX (After Effects)
Infrastructure: AWS (EC2, S3, Lambda, Step Functions, Amplify), Vercel, Docker, Nginx, CI/CD
End-to-end ownership from product thinking to deployment - clean, maintainable, scalable code with clear communication and structured execution. If you're building something that needs to be done right the first time - let's build it properly.
