System design concepts every Nigerian backend dev must know:
→ Idempotency — same request, same result, no duplicates
→ Eventual consistency — distributed systems don’t update instantly
→ Circuit breaker — stop calling a failing service automatically
→ Dead letter queue — catch failed jobs before they disappear
→ Optimistic locking — prevent concurrent writes from corrupting data
→ CQRS — separate read and write models for high-traffic systems
→ Saga pattern — manage multi-step transactions without distributed locks
These aren’t interview concepts.
They’re what keeps your payment system running at 3AM.
Save this.
Over the last 7 years, I’ve focused a lot of my attention on getting more people into tech in Africa.
And for the past 4 years and 7 months, @AltSchoolAfrica has been providing technical and non-technical courses, and now it’s time for the next phase of AltSchool.
The next phase that’ll make proper education accessible to all Africans.
It won’t be easy, but it’ll be worth it.
Follow me as we step into the new phase of education in Africa. When I say education, I mean yes. EDUCATION.
SPEAKING SOLEMNLY
Anyone living in sexual sins (fornication, adultery, pornography, etc), has no place in Christian ministry. Immorality is a very big deal, scripturally. The believer's BODY is the temple of the Holy Spirit. Yes, the BODY. Therefore, what you do with God's dwelling place must be of colossal significance. Don't you see it?
And, because of the sacredness of Christian ministry, while you can legitimately be a struggling Believer for a season, you cannot be a struggling minister, if the struggle is that you have not overcome sexual immorality. In this regard, the category of a struggling minister does not exist, biblically considered.
This is not about being a "wounded soldier." But in any case, if a soldier takes a bullet during combat, we don't hand him over to the enemies, yes. And we also don't leave him in the frontline to continue fighting – with his wound. We take him out and away for treatment. Whether he can even return to active duty later on depends on the severity/impact of the 'wound' sustained and the assessment of the team managing his case. Taking him out of combat is a responsible act of love and not a case of "condemning our own."
Back from the digression. It is alien to the spirit of Christ, to say someone is a minister of the gospel, even though he commits immorality. The practice of immorality cannot coexist with legitimate practice of ministry. A fornicator or an adulterer is not a Minister. Cannot be.
A minister of the gospel MUST be above reproach. People MUST be safe under his care. Money, too, MUST be safe under his care. The bible insists that he sustains a high level of integrity – morally, ethically, socially.
This is why the Charismata, the gifts of the Spirit are never mentioned as qualification or eligibility for ministry. Check the texts.
So, the practice of equating giftedness with eligibility for ministry is unbiblical and should be discouraged. Being a gifted speaker, for instance, does not qualify anyone for Christian ministry. If you know all the Rhema in the book, and all the historic fine points of orthodoxy, but you're an intermittent fornicator/adulterer, you are ineligible for Christian Ministry. You need to be discipled, you should not be discipling anyone, at all.
Read the passage below carefully, to the very last verse, please: It says a Pastor:
"...must be a good man whose life cannot be spoken against. He must have only one wife, and he must be hard working and thoughtful, orderly, and full of good deeds. He must enjoy having guests in his home and must be a good Bible teacher. He must not be a drinker or quarrelsome, but he must be gentle and kind and not be one who loves money. He must have a well-behaved family, with children who obey quickly and quietly. For if a man can’t make his own little family behave, how can he help the whole church? The pastor must not be a new Christian because he might be proud of being chosen so soon, and pride comes before a fall. (Satan’s downfall is an example.) Also, he must be well spoken of by people outside the church—those who aren’t Christians—so that Satan can’t trap him with many accusations and leave him without freedom to lead his flock"
On the last point above, many people who work in Hotels don't take the church seriously because the see the behind-the-scenes lifestyle of Pastors. A minister must have one life, must be not be two-faced. And he must be an example to both insiders and outsiders.
If the church is weak, Satan is only a remote cause. If the church is weak anywhere, the church is the reason why.
And now, may the glorious Lord of the church step into this seeming perpetual desolation, and pour us the blessing that is Revival.

Before you accept that offer, open Glassdoor.
Most people use it to find jobs. The smarter move is to use it to investigate the ones that find you.
Start with the reviews but do not read them the way most people do. Do not look for the overall star rating. That number is almost meaningless. What you are looking for is patterns.
If five different people across five different years are all saying the same thing - management doesn't communicate, payments are delayed, they overpromise during hiring - that is not a coincidence. That is the culture of the company.
Then go to the interviews section. This one is underused and it is gold. People who interviewed with this company left notes on what the process was like, what questions they were asked, how long it took, and whether the offer matched what was advertised.
If someone says the salary they were offered was significantly lower than what was posted, you now know you are walking into a negotiation where they are already starting low.
Check the CEO approval rating. Not because the CEO runs your day-to-day, but because leadership shapes everything - how decisions get made, how teams are treated, how fast things change. A 30% approval rating from the people who work there is information.
Look at how the company responds to negative reviews. A company that replies to criticism with defensive corporate language and zero accountability will treat you the same way when something goes wrong.
Finally, cross-reference what you find. If Glassdoor reviews say one thing and their LinkedIn posts are full of "best place to work" content, trust the reviews. People leave those anonymously. The LinkedIn posts have a marketing budget behind them.
Do your due diligence on a place that is going to have access to your time, your energy and your skills.
Treat it accordingly.
