Building AI-powered products, scalable backend systems, and intelligent software that solve real-world problems.
A career, at scroll-speed.
From electronics fundamentals to production-grade AI platforms. Each stage compressed into the mesh.
Electronics Engineering
Signal chains, circuits, embedded systems — where hardware meets logic.
Software Development
Full-stack fluency: shipping apps that people actually run.
Backend Engineering
APIs, pipelines, and the plumbing that keeps the internet honest.
Artificial Intelligence
Applied ML, evaluation, and building intelligence into products.
LLM Evaluation
Prompt suites, adversarial testing, RLHF loops that push model quality.
Prompt Engineering
Systematic prompt design at scale — reliability over cleverness.
AI Products
Prep.AI, evaluators, agentic tools — production-grade AI shipping.
Large-Scale Search Systems
49M+ indexed records. Query parsing, normalization, sub-100ms latency.
Production Ready Platforms
Enterprise backends, robust observability, systems that hold under load.
Enterprise-grade releases
Every project is treated like a product launch: schematics, telemetry, and evaluation matrices included.
