Akshat Kumar.
Software engineer with 2+ years across full-stack, data automation, and AI-assisted engineering. Building tax compliance pipelines in Python with LLM-powered agents — and quietly architecting things at home on a Debian box.
A quick introduction.
I write code that turns messy real-world data into clean, audit-ready outputs. At EY, I build tax-compliance pipelines with Python, Polars, and FastExcel — processing 50K+ row datasets with 100% accuracy and replacing brittle regex with LLM-powered document agents.
Before that, I shipped React frontends at scale (500K+ MAU at Hoichoi), built whitelabel templating systems for healthcare, and made the jump from Node.js to Go for concurrent data work. I run a small homelab on a Debian box behind Cloudflare tunnels — the same place this site might end up living.
Outside of work I'm usually reading engineering blogs, grinding LeetCode, or experimenting with agentic workflows in Claude Code.
Where I've been.
Three companies, two cities, one thread — building things that handle real data at real scale.
Data Automation Engineer
Ernst & Young — Tax Technology
- Engineered Python pipelines (Polars, FastExcel) automating tax-compliance workflows — reclaiming 300+ hours annually from manual prep.
- Architected transformation engines processing 50K+ rows/file with 100% accuracy for GSTR-1 and 3B reconciliations.
- Built LLM-powered document agents on the Anthropic Claude API, replacing brittle regex parsers for unstructured PDFs and scans.
- Integrated Claude Code CLI into daily development, accelerating automation delivery by ~60%.
Independent Software Engineer
Self-Hosted Infra & Open-Source Research
- Designed and deployed a bare-metal Debian 13 server hosting 24/7 internal services via Docker.
- Engineered secure remote access using Cloudflare Tunnels with Cloudflare Access (OTP) — zero open ports.
- Ported legacy Node.js apps to Go, leveraging goroutines and channels for concurrent data processing.
Software Development Engineer 1
CAW Studios — Client: Hoichoi (OTT)
- Engineered caching layers that cut API load times by 35% across the streaming platform.
- Built secure session management for 500K+ MAU with Iron Session for stateless auth.
- Led frontend for profile management, applying Atomic Design to reduce UI inconsistencies.
Associate SDE
CAW Studios — Client: Novocuris (Healthcare)
- Created a whitelabel templating system for 10+ hospital brands, shrinking deployment from months to two weeks.
- Built a Python scraping engine (BeautifulSoup/Scrapy) ingesting 10K+ records daily.
- Cut data-access latency by 60% via optimised Express.js APIs.

Things I've built.
A few projects worth showing.
Personal Finance Tracker API
Modular Express.js backend with PostgreSQL for auth, expenses, and budgeting. Behavioural scoring, transaction ledger with reversals, JWT-secured APIs, and a written design doc.
Homelab on Debian 13
Bare-metal server running 24/7 internal services. Docker for isolation, Cloudflare Tunnels for zero-port secure access, Cockpit + Uptime Kuma for ops visibility.
LLM Document Agents
Production parsing agents on the Anthropic Claude API — extracting structured tax data from messy PDFs and scans, replacing brittle regex with high-confidence reasoning.
dev-agents
Agentic developer tooling: 21 specialist agents for Claude Code / OpenCode that dispatch in parallel.
