Hi, I'm Pranesh,
I turn ideas into products people enjoy using.
Full-stack engineer with 2+ years of production experience. I take products from the first sketch to the final release — shaping the experience, solving the hard engineering problems, and sweating the details people actually feel. I care about building software that is useful, dependable, and a genuine pleasure to use.

About me
I'm a full-stack engineer with 2+ years of production ownership across backend, frontend, and data. I build complete products: the interface, the API, the relational model, and the pipeline that deploys it. My work spans privacy-first desktop and mobile apps, applied AI, browser-based 3D tools, and the data infrastructure that keeps them reliable.
At ZIMT, University of Siegen, I built and operated an 8+ microservice network-anomaly platform with sub-200ms alert latency, and cut query latency by roughly 40% by redesigning SQL/NoSQL schemas and indexes. Today I work independently on open-source products: Enclave, a zero-knowledge knowledge base with encrypted peer-to-peer sync, and Nexus, a self-hosted learning portal with grounded citations, practice tools and spaced repetition. I also maintain Sentinel and Ratio, and build Weft, Tempo, JournalEdge and other tools that explore how people and agents work with software.
I hold an M.Sc. in Human-Computer Interaction from the University of Siegen. My thesis evaluated AI workflows and the accuracy and efficiency of Figma-to-code tools. That research background shapes how I build: measure, test with real users, and improve the details people actually feel.

How I work
A few principles that show up in every project, whether it is a notes app, a learning portal or a 3D tool.
Understand the problem before the stack
I start with the user, the constraints and the failure modes. The technology choice comes after the problem is clear.
Ship the smallest complete version
A useful vertical slice beats a half-finished platform. I prefer a small release that works end to end, then iterate from evidence.
Make it observable and reversible
Logs, tests, migrations and rollback paths are part of the feature. If it cannot be inspected or undone, it is not finished.

- ▹Shipped Nexus, a self-hosted learning portal on React 18, TypeScript, Node.js, tRPC, Drizzle ORM, PostgreSQL 16 and pgvector, with streaming, citation-grounded answers over WebSocket.
- ▹Built a Redis and BullMQ asynchronous indexing pipeline for chunking and embeddings, decoupling ingestion from query load and holding retrieval to ~100k chunks per workspace under a second.
- ▹Designed and shipped Enclave, a local-first AI knowledge platform with a Rust core (Tauri v2), conflict-free sync, peer-to-peer sync over local networks, end-to-end encryption, encrypted storage and offline operation across desktop and Android.
- ▹Built an offline RAG pipeline with local LLM inference and ONNX embeddings, plus prompt-engineering and tool-calling patterns for grounded, traceable answers.
- ▹Automated CI/CD quality gates covering typecheck, Playwright end-to-end tests, CodeQL static analysis and secret scanning — taking each feature from ideation to deployment and maintenance.

- ▹Built and operated a Python and FastAPI ingestion and TCP/UDP network anomaly-detection platform spanning 8+ distributed microservices (Celery, Redis, SQL), sustaining sub-200ms alert latency in production.
- ▹Integrated three backend services into one MEVN application (MongoDB, Express, Vue.js, Node.js) with custom middleware, a backend instance switcher, event-based logging and a unified Vue.js dashboard.
- ▹Reduced database and query latency by approximately 40% by redesigning SQL/NoSQL schemas and optimizing indexes across PostgreSQL, MySQL, MongoDB and Redis.
- ▹Cut deployment time by up to 60% by automating provisioning and CI/CD with Ansible, GitLab CI/CD, Docker and automated testing on Linux.
- ▹Upgraded production Node.js runtimes to v22/v24 and hardened service authentication with JWT, RBAC/ABAC and LDAP integration.
- ▹Operated containerized production workloads with Docker and Kubernetes on Linux, maintaining 99.5%+ uptime through monitoring, observability and incident response; working knowledge of OpenShift.
What I'm up to now
Building Nexus and Enclave
Two open-source products I own end to end: Nexus, a self-hosted learning portal with grounded citations, practice tools and spaced repetition, and Enclave, a zero-knowledge knowledge base with encrypted P2P sync and offline RAG.
Building Weft
An agent-native design canvas: plain-text design files, a browser editor, a CLI, an MCP server and a live bridge — so designers and coding agents can shape the same product.
Maintaining open-source tools
Sentinel (change monitor) and Ratio (Android money manager) — both with CI/CD, docs and security policies. JournalEdge (trading journal) is an early prototype.
Building Tempo
A browser-based 3D volleyball play designer and teaching tool, exported as shareable video from the browser.
Just finished my M.Sc.
Human-Computer Interaction at the University of Siegen (April 2026), with a thesis on AI workflows and Figma-to-code accuracy and efficiency.
