Sefism.

A to Z

Glossary

Every concept in this sheet, plus the smaller terms it uses. Select a concept to open its card.

A
A project from your old field
A project that solves a real problem from your previous degree or job: a tool, an automation, an analysis or a test plan for software used in that field.
Asking for help well
Asking after a short, time-boxed attempt, with what you tried, what you expected and what happened.
B
Background to role map
Common, sensible pairings: electrical engineer to embedded or data, teacher to technical writing or developer education, accountant to data analytics, designer to frontend or UX, customer support to QA or support engineering.
Bootcamp
An intensive, usually paid training programme lasting weeks or months, often with a cohort, instructors and career support.
Brag document
A running private list of what you did, learned and helped with, with dates and links.
Bridge role
A role that mixes your old domain with a tech skill, such as a finance data analyst, an edtech content engineer, a health informatics analyst or a QA engineer for banking software.
C
Career changer headline
A LinkedIn headline naming the target role and the edge your background gives, rather than your old title or "aspiring".
Career changer resume
A resume that puts a short summary and relevant projects near the top, then your previous experience rewritten to highlight transferable results.
Case study write-up
A one-page account of a project: the problem, who it was for, what you built, decisions and trade-offs, results and what you would change.
Certificates used sensibly
Treating certificates as structured learning and a small signal, not as proof.
D
Decision checkpoints
Dates set in advance when you review progress honestly and decide whether to continue, adjust the target role or pause, based on evidence rather than mood.
Degrees and online degrees
Formal qualifications, from full-time degrees to part-time online options such as tuition-free bachelor degrees and online masters that admit graduates of other fields.
Demand check
Counting current junior or entry-level postings for your target role in your city, region or remote market, and noting what they ask for.
Domain advantage
The edge you get from understanding an industry: its problems, vocabulary, regulations and users.
E
Entry points into tech
The roles people commonly enter tech through: frontend, backend or full stack developer, data analyst, QA or test engineer, support or solutions engineer, IT support, UX designer, technical writer and product roles.
F
First open source contribution
A small, accepted change to a public project: a documentation fix, a test, a translation or a labelled beginner issue.
Free versus paid learning
The choice between free curricula, which cover most beginner material, and paid courses, bootcamps or degrees, which add structure, deadlines, feedback or a credential.
Freelance first
Taking small paid or volunteer projects for real clients, such as a local business website, a nonprofit dashboard or automation for a former colleague, before a full-time role.
I
Impostor feelings
The sense that you do not belong and will be found out, common among career changers surrounded by people with CS degrees.
Income-share agreement
A deal where you pay nothing upfront but owe a share of your future income for a period once you earn above a threshold, up to a cap.
Informational chat
A short, low-pressure conversation with someone already doing the role you are considering, to learn what the work is really like.
Internal transfer
Moving into a tech or tech-adjacent role at the employer you already work for, often after taking on technical tasks in your current role.
Internships for career changers
Internships and graduate or trainee programmes that accept people from other degrees or careers, including remote and part-time ones.
K
Keeping the learning habit
Continuing a smaller, steady learning routine after you are hired, focused on what your job actually needs.
Keeping your job while switching
Learning and building on evenings, weekends or reduced hours while keeping your current income until you have skills, proof and ideally an offer.
L
Learning in public
Sharing what you learn and build as you go: short posts, write-ups of problems you solved, or notes on a project's decisions.
Learning log
A short dated note after each session: what you did, what confused you and what you will do next.
N
Not starting from zero
The idea that a career changer brings professional habits a new graduate lacks: reliability, communication, dealing with clients and managers, and domain knowledge.
O
One curriculum at a time
Choosing one structured, well-known path for your target role, such as The Odin Project, freeCodeCamp, CS50 or a data analytics course, and finishing it before adding others.
P
Pay reset
The chance that your first tech salary is lower than what you earn now, especially if you are experienced in your current field.
Proof over credentials
Evidence of skill that anyone can open and check, such as a deployed project, a data report, a merged pull request or a written case study, rather than a list of courses taken.
Q
Questions to ask a bootcamp
The checks before you pay: full outcome report with starters and finishers, what counts as a job, recent graduates you find yourself, who teaches, live help hours, refund policy and total cost.
R
Reframed experience
Bullets from your previous role rewritten to show outcomes that tech roles care about: data you analysed, processes you improved, tools you introduced, people you trained.
Returnship
A paid, time-limited programme for experienced people returning after a career break, with training and a real project, usually run by larger employers.
Role taster project
A small project, done in a weekend or two, that gives you a feel for a role before committing: a tiny web page, a spreadsheet analysis, a test plan for an app, a short how-to guide.
Runway
How many months you could cover essential costs with savings and any other income if you earned nothing from work.
S
Scoped project
A project small enough to finish in a few weeks at your weekly hours, with a clear list of what it will and will not do.
Stepping-stone role
A job that is not your final target but gets you inside tech, such as IT support, QA, technical support or a data entry role with analysis duties.
Sustainable pace
A weekly study load you can keep for a year alongside work, family and rest, rather than a sprint you abandon after three weeks.
Switch timeline
The realistic time from starting to learn to a first paid tech role.
T
Tech apprenticeship
A paid role that combines work with structured training, often open to people without a degree or relevant experience.
The "why switch?" answer
A short, honest answer to why you are moving into tech: a moment or problem that pulled you in, what you did about it, and why this role.
The entry-level market
The supply and demand for junior tech roles in your city or remote market.
The family conversation
An honest talk with the people affected by your switch about the time it takes, the money involved, the risk and how they can help.
The full cost of a switch
Everything a switch costs: course fees, a laptop and internet, exam fees, and the biggest one, the income and time you give up while learning or taking a lower first salary.
Training fee scams
Fake job offers or "placement promised" schemes that ask you to pay for training, equipment, visas or certificates before you can start.
Transferable skills
Skills from your previous degree or work that tech roles also need: analysis, writing, teaching, handling customers, managing projects, working with numbers, debugging physical systems.
Tutorial hell
The loop of finishing one course or video series after another while feeling unable to build anything alone.
U
Using your background at work
Volunteering for work where your previous field helps: talking to users in that industry, reviewing requirements, spotting unrealistic assumptions.
W
Warm referral
An introduction or referral from someone who knows you or your work, earned through genuine contact over time rather than cold requests.
Weekly hours budget
The number of hours a week you can truly give to learning after work, family, travel and sleep, found by tracking a normal week.
When a degree matters
The situations where a degree is still required or strongly preferred: some large employers and government or bank roles, graduate programmes, many work visas abroad, and research or specialist roles.
Why switches stall
The common reasons people give up: no clear target role, jumping between courses, never building anything original, never talking to anyone in the industry, and quitting a job before savings or skills were ready.
Y
Your first job is not forever
Treating the first tech role as the place to gain one to two years of real experience, not the perfect final destination.
Your first weeks as a switcher
The early period when you learn the codebase or tools, the team's ways of working and who to ask, while colleagues learn what you bring.
Your switch in one sentence
A single sentence that connects where you came from, what you can do now and where you are going.
