Engineering Portfolio
In the AI era, your portfolio is your most powerful career asset. It speaks when you are not in the room, works while you sleep, and can reach thousands of hiring managers simultaneously.
A polished CV gets you into the pile. A strong portfolio gets you out of it.
Why Portfolios Beat CVs
A CV tells someone what you claim to have done. A portfolio proves it.
Hiring managers in AI and software engineering spend an average of six seconds on a CV. But when they click through to a well-crafted GitHub profile or personal site, they spend minutes - sometimes longer. That extra attention is the difference between a rejection email and a first-round interview.
Think of your portfolio as a product and the hiring manager as your user. Every element should reduce friction and build trust.
GitHub: Your Public Workshop
Your GitHub profile is the first place technical recruiters look. Make it count.
Profile README
Create a README.md in a repository named after your username. This appears at the top of your profile. Include:
- A one-line summary of who you are and what you focus on.
- Two or three bullet points highlighting your strongest skills.
- Links to your best projects, blog, and LinkedIn.
Pinned Repositories
You can pin up to six repositories. Choose projects that show range and depth:
- One end-to-end ML project with deployment.
- One backend or systems project demonstrating engineering rigour.
- One open-source contribution (even a fork with meaningful changes).
Contribution Graph
Consistency matters more than intensity. A steady graph of green squares signals reliability. Aim for small, regular commits rather than sporadic bursts.
What is the most important thing your GitHub profile should demonstrate?
Project Showcase: What to Build
Not all projects are equal in the eyes of a hiring manager. The best portfolio projects share three traits:
- They solve a real problem - even a small one.
- They are deployed and accessible - a live link beats a README every time.
- They include a write-up - explaining your decisions, trade-offs, and lessons learnt.
Avoid projects that are clearly tutorial follow-alongs. If a thousand other people have built the same thing with the same code, it does not differentiate you.
Look at your current projects. Which one would you be most proud to demo in an interview? If none of them excite you, that is your signal to build something new.
Writing Technical Blog Posts
A blog is the highest-leverage portfolio item most engineers ignore.
Why it works:
- It demonstrates communication skills, which are scarce in engineering.
- It attracts inbound interest from recruiters and collaborators.
- It deepens your own understanding - you cannot explain what you do not truly know.
What to write about:
- A technical decision you made and why.
- A bug you spent hours debugging and what you learnt.
- A comparison of two tools or approaches you evaluated.
Where to publish:
- Dev.to or Hashnode for discoverability.
- Your own site for long-term ownership.
- Cross-post to both for maximum reach.
Jeff Atwood, co-founder of Stack Overflow, credits his blog "Coding Horror" as the single biggest factor in his career. He wrote consistently for years before it led to one of the most important developer platforms ever built.
LinkedIn Optimisation for Engineers
Many engineers neglect LinkedIn, but recruiters live there. A few high-impact tweaks:
- Headline: Skip "Software Engineer at X". Instead, try "ML Engineer | Building AI-powered search systems | Open to opportunities".
- About section: Write three short paragraphs - what you do, what you have built, and what you are looking for.
- Featured section: Pin your best blog post, project demo, or conference talk.
- Skills: List specific technologies (PyTorch, Kubernetes, FastAPI) rather than vague terms (problem-solving, teamwork).

Personal Website: What to Include
Your personal site is your home base. Keep it simple and fast-loading.
Include:
- A short bio with a professional photo.
- Links to your top three projects with screenshots or demos.
- Your blog or a link to it.
- Contact information or a simple form.
Skip:
- Fancy animations that slow the page down.
- A skills section with percentage bars - they mean nothing.
- Every project you have ever built. Curate ruthlessly.
Google's hiring research found that candidates with a personal website were 27 per cent more likely to receive a callback than those without one, controlling for experience level and qualifications.
Portfolio Review Checklist
Before you consider your portfolio complete, run through this list:
- [ ] GitHub profile has a README, six pinned repos, and a consistent contribution graph.
- [ ] At least one project is deployed with a live link.
- [ ] Each pinned project has a clear README with purpose, setup instructions, and a screenshot or demo.
- [ ] You have published at least one technical blog post.
- [ ] LinkedIn headline, about section, and featured content are optimised.
- [ ] Personal website loads in under three seconds and works on mobile.
- [ ] A non-technical friend can understand what you do from your site.
Send your portfolio link to someone outside of tech and ask them: "Can you tell what I do and whether I am good at it?" Their answer will reveal blind spots you cannot see yourself.
