Engineering & Creativity

Born January 8, 2007.

About me

I work at the intersection of engineering, design, distribution, and music, and I'm trying to widen it.

Most recently I built Julie, an Android assistant that gets things done across calls, calendars, contacts, and the browser. It's in private early access with 30+ users.

My engineering runs from agent tooling down to embedded systems. Retrace is a self-correcting layer for coding agents, and before that I built a real-time synthesizer on a Raspberry Pi.

On the design side, I handle positioning, brand identity, websites, and launch films for AI startups and consumer tech companies. Most technical products are better than the way they're explained, and that gap is what I work on.

I also sell what I build. Zenvex reached 50+ SDR agencies entirely through organic content, and I've run cold outreach and in-person sales for my own products. I treat distribution, marketing, and sales as part of building a product.

I've been producing music for seven years, working with hip-hop artists across India and helping shape the sound of the scene.

I study computer science at the University of Essex, and I'm pushing into hardware next: electronics, robotics, and mechatronics.

Experience

Julie

2026 — Present

Solo Founder · India / London

Started with multilingual voice agents used by 10+ businesses in India, then pivoted to a consumer AI assistant. Built an agentic Android app with device integrations, Google OAuth, and provider routing. Now in private early access with 30+ users.

Zenvex

Feb — Sep 2026

Solo Founder · Remote

Built a pipeline recovery platform used by 50+ SDR agencies, acquired entirely through organic content. Connected HubSpot, Apollo, and Instantly to detect stalled deals, score recovery likelihood, and automate re-engagement.

NestJS / PostgreSQL / Prisma / Redis / BullMQ

Government College of Technology

May — Jun 2023

Technical Intern, Systems & Infrastructure · Coimbatore

Documented network topology and server-monitoring infrastructure for institutional IT serving 1,000+ students.

What I built

Retrace

2026

A self-correcting layer for coding agents. Terminal-installable tooling that executes, evaluates failures, stores reflections, and retries with prior context. Built on the Reflexion architecture.

Python / LLM APIs / CLI

Scripelle

2025 — 2026

An open-source AI writing environment for long-form work, with context-aware generation and prompt pipelines designed to work reliably with sparse input.

TypeScript / React / LLM APIs

Embedded audio synthesizer

2024

A real-time synthesizer on Raspberry Pi. Traced 12 ms of latency to buffering and thread scheduling, then tuned execution for stable audio output.

Raspberry Pi / Linux / C / Audio DSP

Tabu search vs. hill climbing

2023

Built a genetic algorithm with interchangeable search heuristics and benchmarked them across 1,000 runs. Found Tabu's advantage was marginal and sensitive to mutation rate.

Python / NumPy / scikit-learn

Education

University of Essex

Expected May 2028

BSc Computer Science · Colchester, UK

Year 1 average: 83.5% (First Class standard). Ranked top of class.

Studying algorithms, data structures, computer systems, AI, databases, and the mathematics behind them.
