Hi everyone,

I wanted to share my situation and hopefully get some guidance from people who have already been through this journey.

I graduated with a B.E. in Mechanical Engineering in 2020. After graduation, I spent a few years preparing for government exams. Eventually, I realized that path wasn't for me and decided to move into technology.

Over the last couple of years, I've been exploring different areas. I started learning programming, then RPA, and later came across blockchain. The more I learned about it, the more interested I became.

Since then, I've studied blockchain fundamentals, Ethereum, Solidity, Go, Hyperledger Fabric, REST APIs, and MongoDB. I've also built a few small projects and recently completed a Hyperledger Fabric project as part of my learning.

The reason I'm posting is that I feel a bit stuck.

I've spent a lot of time learning, building connections on LinkedIn, and trying to understand the industry. But when I look at job openings, most seem to expect several years of experience, and sometimes I wonder if I'm focusing on the right things.

Some of the concerns that are always in the back of my mind are:

My non-tech background
The career gap after graduation
Limited real-world industry experience
Communication skills (I'm naturally introverted)

At the same time, I'm serious about making this transition work. I'm 28 years old, willing to put in the effort, and can consistently dedicate 3–4 hours every day to learning and improving.

I'd genuinely appreciate advice from people working in blockchain or software development:

What would you focus on if you were in my position?
What skills or projects should I prioritize next?
Are there any gaps in my current approach that I'm not seeing?
What would be the fastest realistic path toward becoming job-ready?

I'm not looking for shortcuts—just a clear direction and an honest assessment of where I stand.

Thank you for reading, and I appreciate any advice you can share.

Your Mechanical Engineering degree and 2020 graduation year are not the biggest issue here. The bigger issue is that your learning currently needs a clearer hiring direction.

You have mentioned blockchain fundamentals, Ethereum, Solidity, Go, Hyperledger Fabric, REST APIs, and MongoDB. That is a good start, but for hiring teams it may look scattered unless you connect it to one entry-level role path.

Before learning more tools, I would first narrow your target.

Are you trying to become a junior smart contract developer, a blockchain backend developer, a Hyperledger Fabric / enterprise blockchain implementation trainee, or a Web3 QA/testing candidate for blockchain applications?

Because each path needs a different proof stack.

For example, a junior smart contract developer profile needs Solidity projects, test cases, deployment notes, and basic security awareness. A blockchain backend profile needs APIs, database work, wallet/blockchain integration, and clean backend logic. A Hyperledger Fabric profile needs chaincode, network setup, business workflow explanation, and enterprise use-case clarity.

So my first suggestion would be: choose one role direction first, then build 1–2 projects around that direction instead of trying to prove everything together.

Which of these paths feels closest to what you actually want to do?

Thanks for the feedback.

Based on my current skills (Go, REST APIs, MongoDB, Solidity, and basic Hyperledger Fabric), which path do you think would give me the best chance of landing an entry-level role in the current market?

Also, are there any specific projects you'd recommend I build to make my profile stand out?

Thanks for sharing more detail.

Based on your current skills, I would not suggest positioning yourself only as a junior Solidity developer right now. Pure smart contract roles are competitive and usually expect stronger proof around Solidity, testing, security patterns, gas optimization, deployment, and audit-style thinking.

Your better entry path may be blockchain backend developer or Web3 application backend developer with smart contract integration.

Reason is simple: Go, REST APIs, MongoDB, Solidity, and basic Hyperledger Fabric together make more sense when you show that you can connect backend systems with blockchain logic. That is a more believable entry-level story than trying to compete only on Solidity.

For a mechanical engineering graduate transitioning to blockchain backend developer roles with Go REST APIs MongoDB Solidity and Hyperledger Fabric project proof, I would build only 2 strong projects instead of 6 average ones.

Project 1:
Build a smart contract + backend API project.

Example: an escrow, invoice payment, asset registry, or certification verification system where Solidity handles the on-chain logic and your Go/REST API handles users, records, status updates, and database storage. Add MongoDB, API documentation, test cases, deployment notes, and a clean README.

Project 2:
Build one enterprise-style blockchain project.

Example: a maintenance log, machine part traceability, supply-chain event tracker, or asset movement tracker using Hyperledger Fabric or a simulated blockchain workflow. This can connect well with your Mechanical Engineering background because it shows real-world process understanding, not just crypto theory.

The mistake I would avoid is presenting yourself as someone who knows “Solidity + Go + Fabric + MongoDB” separately. Instead, present yourself as someone who can build backend systems that connect real-world data, APIs, databases, and blockchain records.

Your target line can be something like:

“Entry-level blockchain backend developer focused on Go APIs, MongoDB, Solidity smart contract integration, and enterprise blockchain workflows.”

That sounds much clearer than “I am learning blockchain.”

If you build these 2 projects properly and explain them well on GitHub and LinkedIn, your profile will look far more job-ready.

Thank you so much for the advice. This honestly gave me a clearer direction than I've had in a while.

I was trying to learn many things separately, but your point about combining Go, APIs, databases, and blockchain into a complete solution really clicked for me.

I'll focus on building those projects and improving my portfolio.

Just one question: if you were starting out today, what would be the next skill you'd focus on to become job-ready faster?

Thanks again for taking the time to help me out.

Jumping in here because I think your next step should not be learning one more blockchain tool.

You already have a decent base: Go, REST APIs, MongoDB, Solidity, and some Hyperledger Fabric. The bigger gap now is proof. Can someone open your GitHub and quickly understand what you built, how it works, how to run it, and what part of the system you actually handled?

If I were in your place, I would focus on one blockchain backend project for the next 30–45 days.

Not a simple token project. Build something where the backend and blockchain layer both matter.

For example, an asset maintenance log, invoice verification system, certification tracker, or machine-part traceability project. Let the backend handle users, records, API calls, and MongoDB storage. Let the blockchain layer store the proof, status change, hash, or ownership/event record.

Then document it properly:

What goes on-chain?

What stays in MongoDB?

What does the API do?

How can someone run it locally?

What tests have you written?

This kind of project will fit your current skills better than trying to compete as a pure Solidity fresher. It also gives you a stronger story: you are not just “learning blockchain,” you are learning how backend systems connect with blockchain records.

That is a much more practical entry-level direction.

Thanks for the insight. That makes sense—focusing on a complete backend + blockchain project seems more valuable than jumping between tools.

Since I already have foundations in both Ethereum and Hyperledger Fabric, which one would you prioritize based on the current job market and entry-level opportunities? Would you recommend building my portfolio project on Ethereum or Hyperledger Fabric, and why?

Hi, glad the reply helped.

If I have to answer practically, I would suggest Ethereum-first, but not Solidity-only.

For entry-level visibility, Ethereum/Solidity has more openings, more public projects, more hackathons, more GitHub examples, and more chances to show proof. But pure smart contract developer roles are competitive, so I would not position you only as a Solidity fresher.

Your stronger angle is: blockchain backend developer with Ethereum smart contract integration.

That means you should focus on:

Go or backend APIs

MongoDB/database layer

Solidity smart contract integration

testing and deployment

clear GitHub documentation

I would keep Hyperledger Fabric as a secondary strength, not the main focus for now. Fabric is useful for enterprise blockchain, supply chain, traceability, identity, audit logs, and permissioned workflows. Since you come from Mechanical Engineering, Fabric can help you build a project that connects better with industrial or operational use cases. But job openings around Fabric are usually fewer and often expect implementation experience.

So my suggestion would be:

70% focus on Ethereum + backend integration
30% keep Fabric for one enterprise-style project

For projects, don’t build a simple token. Build something where your background adds context.

Example 1: machine maintenance log system
Backend stores machine/service records in MongoDB. Smart contract stores important proof like record hash, approval, timestamp, or ownership/status change.

Example 2: spare part traceability system
API handles part movement, vendor details, inspection status, and database records. Blockchain stores proof of key events.

Example 3: invoice or certification verification system
Backend handles users and documents. Blockchain stores verification proof.

This way your profile will not look like “I learned Ethereum and Fabric separately.” It will look like you understand how backend systems, real-world records, and blockchain proof can work together.

So my short answer is: focus more on Ethereum for entry-level opportunities, but use Fabric and your Mechanical background to build one differentiated enterprise-style project.
