About
Software Engineer with 5 years of experience building web, mobile and backend products with TypeScript, React, React Native, Node.js and NestJS. At Strativ AB, I build LLM-based products on Claude and other model providers: a project knowledge base that is also sold to clients, an AI interviewer used for candidate screening, and MCP (Model Context Protocol) integrations that connect AI tools to internal data. Previously led a team of 8 frontend developers on an ERP product delivered to IFIC Bank, BRAC University and Prime Bank. I make technology choices on projects, review code and mentor junior developers.
▹ LLM products
RAG pipelines, embeddings and pgvector search, MCP servers and tool calling on Claude and other providers.
▹ Full-stack systems
NestJS microservices, PostgreSQL, Redis, queues, payments and CI/CD on AWS, Vercel and Cloudflare.
▹ Web & mobile
React, Next.js and React Native (Expo) apps shipped to the web, App Store and Google Play.
▹ Technical leadership
Led 8 frontend developers, set coding standards, chose tooling, reviewed code and mentored juniors.

It is now also sold to clients as a product.
- +Designed and built MCP-based connections between AI tools and internal knowledge bases.
- +Developed Strativ Greenroom, an AI interviewer that is in active use for candidate screening.
- +Built Chefry, a full-stack content creation platform for chefs, for a client, with a React Native PWA frontend and an Express and PostgreSQL backend. Integrated Stripe payments and real-time notifications, set up CI/CD, managed deployments on AWS and stored uploaded media in Amazon S3.
- +Shipped Biap, a sales and profit-management app, to the Apple App Store.
- +Built the frontend architecture and core application logic for Alent Dynamic, a Swedish industrial IoT platform used by sawmills to monitor and control wood-drying kilns in real time.

Projects
Products I've built at work and on my own, from LLM systems to mobile apps.
Multi-tenant RAG behind an MCP server: AI tools search a project’s docs with hybrid retrieval and reranking.
swipe the diagram sideways · tap a box
1/8Once per project, Claude authorises through OAuth 2.1 and gets a project-scoped token.
~/projects/strativ-context-engine
featuredStrativ Context Engine
Multi-tenant AI knowledge base that lets Claude and other MCP clients search and reason over each project's docs, meeting notes and decisions. Built for every Strativ project and now also sold to clients.
Internally called Open Brain. Each tenant gets its own Supabase project with a pgvector store. Markdown docs pushed to a tenant's docs repo are chunked, enriched and embedded automatically, and an MCP server running as a Supabase Edge Function exposes search, browse, capture and other tools to AI clients such as Claude. A Next.js admin portal manages users, projects and access, and runs its own OAuth 2.1 flow so MCP clients get project-scoped tokens.

~/projects/terncv
featuredTernCV
Free ATS-friendly resume builder that runs entirely in the browser: no account, no server-side storage. Live preview, four templates and text-based PDFs that applicant tracking systems can read.
Each exported PDF carries the resume data, so importing it restores the resume for editing. Supports multiple resumes, undo/redo, drag-and-drop section order and sync between open tabs. A paid custom-CV service runs on a Vercel serverless function behind Cloudflare Turnstile; finished CVs are published encrypted (AES-GCM, PBKDF2-derived key) and opened with a security code. Tested with Playwright end-to-end tests and served under a strict Content Security Policy.

Cross-platform sports community app connecting players, teams, coaches and venues. Published on Google Play.
A "looking for" matchmaking system where users post and answer requests for opponents, players, coaches, teams or venues, with Socket.io real-time chat to arrange matches. Social feed, map-based venue discovery and live cricket scorecards, shipped to iOS, Android and web (PWA) from one Expo codebase, with phone OTP sign-in and JWT refresh-token sessions.

Strativ Greenroom
AI interviewer in active use for candidate screening. Candidates answer spoken questions, the system transcribes them live, adapts its follow-ups and produces an assessment for recruiters.
Greenroom runs a structured, spoken screening interview. Each answer is transcribed in real time, summarised by an LLM and fed into a phase machine that decides between a follow-up and the next question. Recordings upload in the background throughout the session, and after the interview a job pipeline produces a full transcript and an assessment for the recruiter.
