Real-Time Offer Negotiation
React · TypeScript · Node.js · PostgreSQL · Socket.io · Stripe
Built an end-to-end offer and counter-offer system with live updates, payment on acceptance, scheduled expiration, and bulk imports.
Software engineer. Curious human.
A little curiosity.
A lot of “what if?”
Software that works.
I’m Lera. I turn complicated systems into thoughtful, dependable experiences—from the database to the very last button. Full-stack, cloud, and a healthy suspicion of anything described as a “quick fix.”
Good systems. Fewer headaches. A little personality.
01 / Selected engineering work
Less friction.
More “that just works.”

Selected professional and independent work. Production implementations belong to their respective employers.
02 / The experience
Ideas are lovely.
Shipping is lovelier.
2026 – Present

2024 – 2025
Cloud & DevOps · Independent Projects
Built AWS infrastructure with Terraform, Docker, Kubernetes, and CI/CD pipelines, with a focus on security and repeatable deployment.
2021 – 2023
Programming Instructor · Dreamaker
Taught Python, algorithms, object-oriented programming, and engineering fundamentals to more than 200 students.
03 / Behind the keyboard
Serious about the work.
A little less serious about myself.
I have an M.S. in Computer Science from the University of Bridgeport and a B.S. in Computer Science & Technology from Hebei University of Science & Technology. I work across TypeScript, React, Node.js, PostgreSQL, Redis, AWS, and infrastructure automation. I care about software that’s useful, secure, and built to last.
I like asking good questions, untangling tricky systems, and making things feel easier than they were to build. Previously, I taught programming to more than 200 students—excellent practice for explaining complicated things without making anyone regret asking.

Have a good problem?
I’m all ears.
An interesting role, a thoughtful collaboration, or a wonderfully specific engineering question? I’d love to hear it. Bonus points if it starts with “what if.”
