Hi, I'm

Vivek Vijai

Backend Developer & Product Owner

I build Django backends the way a product owner thinks - checkout flows, payment logic, and cloud deployments, shaped by 5 years of understanding what actually drives a business. Currently shipping the full stack at a Swedish food-tech startup, solo.

Working Style

Ownership

Sole backend developer and product contributor on a live commercial platform, from Figma flows to production backend decisions.

Judgment

Analysed Klarna's margin cost against our average order value and recommended deferring it - card and Swish cover current needs at lower cost.

Adaptability

Rebuilt from five years in pharma sales into backend engineering while shipping production code and learning fast.

01.About Me

I am a backend developer based in Stockholm, Sweden, open to opportunities across the country. My core stack is Python, Django, Django REST Framework, PostgreSQL, Redis, Stripe, Docker, Azure App Service, GitHub Actions, pytest, JWT, CORS, Gunicorn, React/Vite integrations, RAG workflows, WhatsApp Business API, and Meta Graph API.

At PeckiiLess AB, I am the sole backend developer and product contributor for a live Swedish food-tech platform. I shaped the user journey in Figma, defined checkout from cart to date and slot selection to payment, and built the backend from scratch with Azure deployment workflows. I also evaluated Klarna's transaction cost against our current order volume and recommended holding off for now, keeping Stripe's card and Swish integration as the leaner near-term path.

Alongside that, I am building AI and API-integration projects for Tellus AB, a Swedish startup: a WhatsApp-based RAG assistant for customer conversations and appointment booking, plus a planned Meta ads dashboard integration with an AI campaign-suggestion layer.

I enjoy problem solving, taking ownership of products end to end, and learning by building. Having owned major product areas independently, I am now looking to join a strong engineering team - not to be handed easier work, but to be pushed. I want engineers around me who will question my architecture, so the next backend I build is better than the last one.

Before tech, I spent five years in pharma sales and marketing in India. That background shapes how I build: I think about users, margins, operational constraints, stakeholder communication, and the business trade-offs behind engineering decisions.

02.Experience

P

Backend Developer & Product Contributor

PeckiiLess AB / Stockholm County, Sweden

November 2025 - Present / 8 months

Sole backend developer for a Swedish food-tech platform covering daily food ordering, catering, and event services.

  • Architected and built the Django REST API from scratch - PostgreSQL schema, cart and checkout logic, delivery date/slot scheduling, JWT authentication, CORS for a React/Vite frontend, Redis caching, and consistent DRF JSON error responses.
  • Implemented Stripe card and Swish payment flows with idempotency handling to prevent duplicate charges.
  • Deployed a Dockerized Gunicorn runtime on Azure App Service with GitHub Actions CI/CD and environment-based configuration; planned backend test coverage with pytest.
  • Designed 20+ responsive Figma screens and defined the full checkout journey.
  • Set a two-day advance booking rule based on operational constraints.
  • Evaluated Klarna against AOV margin impact and recommended deferring it in favor of the existing Stripe card/Swish flow - informing my manager's payment roadmap with a cost-based analysis, not just a technical opinion.
  • Worked in Agile/Scrum rituals: sprint planning, standups, retrospectives.

Other Notable Projects

In Progress

Tellus AI WhatsApp Agent

AI WhatsApp assistant for Tellus AB, a Swedish startup. The agent uses RAG over company resource data so customers can ask natural questions, book appointments through chat, and get escalated to a human when support is needed. Planned deployment on a Hetzner VPS.

Meta API Integration

Planned Tellus AB dashboard integration for Meta ad reporting. Company officials will be able to view customer ad details through their dashboard, then use an AI layer to generate suggested ad campaign ideas from current ad performance reports. Planned deployment on Azure.

Get In Touch

I am based in the Greater Stockholm Metropolitan Area and open to backend developer roles across Sweden. If you are building with Python, Django, APIs, payments, Azure, or product-led backend systems, I would love to talk.
