For final-year students & early-career developers

Tutorials teach syntax. We teach judgement.

Practical software engineering from a developer who has built and run real production systems for [35+] years — the debugging, design trade-offs and career moves that courses skip.

ALERT payroll batch failed at 02:14
→ 1 bad record. 40,000 good ones.
→ Fix the record, or fix the design?
// You'll learn:
✓ read the log before the code
✓ make batch jobs restartable
✓ write the 5-line incident note

The gap

You finished the course. The job still feels out of reach.

What's missing isn't more content — it's the judgement you only get from production: what breaks, why, and what to do at 2 a.m.

The Production-Ready Checklist

[50] checks to run before you call any project "done" — the same list used on systems that handle real money. Print it, pin it, use it on every project.

Who's behind it

Two humans. An AI crew. No sales calls.

We're deliberately small. AI handles the repetitive work so people spend their time where experience matters — your code and your decisions.

That's why prices stay low: no call centre, no "counsellors", no EMI pressure. And you're never told an AI reply came from a person.

Humans do

  • Write and own every lesson
  • Final review on your projects
  • Live mentoring and mock interviews
  • Decide what's worth teaching

AI crew does

  • Answers doubts 24×7, labelled as AI
  • First-pass code review
  • Practice drills and quizzes
  • Study streaks and reminders

Learning paths

LIVE CASE STUDY · IN PROGRESS

Rebuilding a decades-old DOS accounts system for the web — in public.

A real legacy system that still runs annual provident-fund accounts for large public-sector employers. Follow every decision: data migration, keeping old reports identical, and how a one-person team uses AI agents to do the work of five.

Jayadev Lenka

Founder, Sigma_4 Software · Bhubaneswar

I've been writing software for about [35] years — from DOS-era FoxPro and Clipper to client-server and now the web. My systems have handled pension and provident-fund accounts for large public-sector employers in Odisha, where a wrong number isn't a bug report — it's someone's retirement.

DevCraft is the handbook I wish I'd had: what actually matters when code meets real users and real money.
