Paste a job and drop your resume. We reverse-engineer exactly what the role wants, show which requirements your resume already evidences and which it misses, and suggest projects to close the gap.

One run turns a job posting into a clear, honest read on where you stand — and what to do about it.
We reverse-engineer the description into the concrete skills the company is really screening for — separating the must-haves from the nice-to-haves so you know what actually matters.

Every requirement in the posting, checked against your resume one by one, with the exact line that evidences each — and an honest list of the ones nothing backs up yet.
How much of this role's requirements your resume already shows
Our reading of the job description — not a score any employer calculates.
Strong on core backend, but the role leans on distributed systems and container orchestration your resume does not yet show.
For the gaps you can’t paper over, we suggest impressive, role-specific projects — grounded in what actually gets people hired there — so you have something real to build and show.
A weekend each. Pick one, learn the concept, earn the bullet.
What you'll learn
At-least-once delivery and idempotency keys
A queue that guarantees at-least-once delivery will hand you the same message twice — on a retry, a rebalance, or a crash between work and acknowledgement. The consumer, not the broker, has to make the duplicate harmless. You do that by deriving a stable key from the message and recording it before the side effect, so the second delivery finds the key already present and skips the work.
Consume a stream where every message may arrive twice, and make sure the side effect happens exactly once.
The bullet this earns
Built an idempotent Kafka consumer in Go using transactional dedupe keys, verified against deliberate duplicate replay.
Why it impresses: The posting names exactly-once processing. This is the mechanism behind it, built small enough to explain end to end at interview.
Closes gaps: Distributed systems, Exactly-once processing
