Hi! I’m a professional English-Indonesian translator with expertise in translation, editing, proofreading, subtitling, transcription, interpreting, SEO, and copywriting. By focusing exclusively on English and Indonesian, I ensure every project is accurate, culturally relevant, and tailored for maximum impact — whether it’s a document, website, subtitle, or marketing content.

I turn English courses, software, and video into Indonesian that reads like it was written here — and when someone else's Indonesian is already broken, I find exactly what broke. Top Rated, 100% Job Success, 40+ projects delivered.
Most Indonesian translation on this platform is grammatically correct and still wrong. It picks the wrong formality level and quietly insults your users. It ignores that Indonesian runs 15-25% longer than English and breaks your buttons. It renders a training module word for word and leaves the learner more confused than before they started.
That specific problem is what I do for a living. I am a native Indonesian speaker and a working English teacher for 13 years in front of a classroom, watching in real time which sentences land and which ones do not. That is not a footnote on my CV. It is the reason my Indonesian reads at the right level for the audience you are actually trying to reach.
WHAT I DO
• E-learning & training localization — courses, LMS content, onboarding,
assessments, facilitator guides
• App, website & software localization — UI strings, .json / .xliff / .po,
length-safe copy that fits your buttons
• LQA / translation audit — I review Indonesian another vendor delivered and
send you a line-by-line error report with severity ratings
• MTPE — DeepL and GPT output edited to publishable quality, at a fraction of
the cost of full translation
• Subtitling & captions — SRT/VTT, timing, reading-speed (CPS) compliance
• Transcreation — marketing copy rebuilt for Indonesian readers, not
translated at them
• Live interpreting — EN↔ID on Zoom or Meet for meetings, interviews, training
HOW I WORK
1. Free 15-minute scoping call. I tell you what the project actually needs.
Sometimes that is an editor, not a translator, and I will say so.
2. Glossary and style guide first, approved by you, applied to every file.
3. Delivery in your working format — ready to drop into your build or LMS.
4. Two revision rounds included. I do not close a contract until you sign off.
WHO I WORK BEST WITH
EdTech companies and course creators entering Indonesia. SaaS and app teams whose Indonesian was localized cheaply and is now generating support tickets. Media and L&D teams with video that needs subtitles a native speaker will not laugh at.
WHY I AM NOT THE CHEAPEST
Because cheap Indonesian is not cheap. It gets rewritten by your users — in app store reviews, in support tickets, in churn. I would rather quote you honestly once than be the reason you pay for the same job twice.
Send me your source file, or just 200 words of it. I will translate a sample free, tell you what the full project should cost, and be straight with you about whether you need me at all.

Disclaimer: if you're put off by my hourly rate, just 𝐬𝐭𝐨𝐩 𝐫𝐞𝐚𝐝𝐢𝐧𝐠. If you think my profile is overrated, please know that it is totally fine for me that you choose to enlist someone else's help.
But if you think there's a story to how I set up my profile and rate, then by all means, 𝐜𝐨𝐧𝐭𝐢𝐧𝐮𝐞 𝐨𝐧:
Your boss tells you to expand to the Indonesian market. Your advisors tell you to make a website to build your business and make it prosperous. You want to extend your products' reach to the Indonesian audience.
Whatever the case is, this profile that you're looking at and reading has all the qualities that you would need: I'm a professional linguist/translator/writer that sells your products and markets your vision!
Hear the experience of working with me from others first-hand:
"I would highly recommend Yoshua. Produced a market report of a much higher quality than I expected. Will definitely use again." - an export/import businessman.
"Fantastic work. Yoshua met all my expectations. He is very professional in setting up terms of contract in order to deliever work on time." - a fellow translator.
"I would like to provide my highest recommendations to the work and attention of Yoshua Sugandhi. Yoshua worked as a freelance translator for wH as of November 2014. Yoshua was then swiftly promoted to Project Manager of the entire Indonesian team in February of 2015." - an Internet giant.
"Yoshua was a pleasure to work with, and turned around a professional, high-quality translation immediately when we were working with a tight deadline! I look forward to working with him again in the future on translation projects!" - a video advertiser.
=====================================================================
I translate, I interpret, I write, and I advise. More importantly, I deliver!
A translator since 2008, I'm an official member of the Association of Indonesian Translators. When experience meets quality, you'll get yourself a man by the name of Yoshua; and yes, that's me!
English native speakers usually admit that I speak like (if not better than) them - thus the proficiency level. ;)
I have been helping various companies all around the world to establish their businesses in Indonesia: One of my most recent achievements would be raising unique visitor count for a worldwide tech company that is based in the USA - 𝐟𝐫𝐨𝐦 𝟏𝟓,𝟎𝟎𝟎 𝐭𝐨 𝟒 𝐦𝐢𝐥/𝐦𝐨𝐧𝐭𝐡 𝐢𝐧 𝐣𝐮𝐬𝐭 𝐚 𝐲𝐞𝐚𝐫! This shows how effective my leadership and localisation skills were, as I was 𝐦𝐚𝐧𝐚𝐠𝐢𝐧𝐠 𝐚 𝐭𝐞𝐚𝐦 𝐨𝐟 𝟏𝟎𝟎+ 𝐥𝐢𝐧𝐠𝐮𝐢𝐬𝐭𝐬 to achieve this. Imagine how much is your earning alone by having that many visitors to your website!
All this because I know how to touch people's hearts. Hit me up if you want to emotionally reach your customers and build strong relationships with them.
And why the rate?
Think: you hire experienced people, the experts of their fields, to help develop your softwares and platforms. They code, they play around with their stuff to deliver a finished product for you: they translated what you have in your mind into something real.
And yes, translated.
Let me just repeat one more time: 𝐭𝐡𝐞𝐲 𝐭𝐫𝐚𝐧𝐬𝐥𝐚𝐭𝐞𝐝 - 𝐢𝐭'𝐬 𝐭𝐫𝐚𝐧𝐬𝐥𝐚𝐭𝐢𝐨𝐧.
Since you've put that much effort and money into hiring the best human-tech translators, it would make sense if you hire another expert: me, to take care of your human language A-language B translation needs. Combining those tech translators with the wrong linguist would result in disaster, and we don't want that for your business, do we? ;)
Plus, when you hire me, you'll get yourself the most efficient translator (typing at the 𝐬𝐩𝐞𝐞𝐝 𝐨𝐟 𝐥𝐢𝐠𝐡𝐭 of around 𝟏𝟎𝟎 𝐖𝐏𝐌 - plus being a natural reader and writer) on Upwork. Thus, don't let my "high" rate fool you: you get what you paid for by hiring me! All work = done in the speed of light with 𝟏𝟎𝟎% 𝐚𝐜𝐜𝐮𝐫𝐚𝐜𝐲 rate, saving you from further costs that might have had occured had you chose to go another way.
My unique specialisations: game localisation, trading, cryptocurrencies, blockchain, tech, marketing content, transcreation, Christianity, SEO, keyword research, project management, language lead, and many more!
P.S. I also advise crypto projects and can help with any crypto-related stuff that you might need assistance with.
I look forward to being in business with you! Have a great day/night!
