R&D Project Manager · Music Producer · Filmmaker
I work in R&D for optical thin-film coatings by day and make music in my spare time. In 2025 I made a short film about something I care about deeply — the idea that music can connect people across every border, and that a world without war is worth working towards. It was filmed with artists from six continents and submitted to festivals worldwide. Life takes unexpected turns.

After moving to Italy I started josiahheflin.net, a remote music production service that connected me with artists from Canada, the US and elsewhere.
Music storyFilmmaker and video producer — including a CREA-commissioned documentary on maize research, excerpts of which aired on Italian national TV. I made From Chaos to Harmony because I wanted to do something — however small — for a more peaceful world. Along the way I've also picked up web design, graphic work and translation across English, Italian, Hindi and Tamil — you end up doing a lot of things when you just get on with it.
See the filmI made this film because I genuinely believe the world doesn't have to be this way. Wars, walls, us-and-them — I find it hard to accept that this is just how things are. Music has always felt like one of the few things that crosses every border without asking permission, and I wanted to make something that showed that.
So I reached out to musicians on six continents — people I'd never met in person — and we filmed it together remotely. Each artist contributed from their own part of the world, which means the film itself was effectively made across six continents. It's my first film. It's not perfect. But it came from an honest place — a hope that people are more connected than the news makes it seem, and that a world without war is worth believing in.
Founded a recording studio in Chennai. Composed music for independent albums, TV and radio jingles, and background scores. Worked with Father Berkmans, Isaac Joe, Freddy Joseph, and organisations including the Bible Society of India and Jesus Calls.
Led audio production for 30+ weekly TV and radio programmes, plus multiple DVD and CD releases per year at Jesus Calls Studios — one of India's most prominent broadcast ministries.
After moving to Italy, a message from a fan in Canada reignited the music career. josiahheflin.net was born — a fully remote music production service connecting vocalists and songwriters across the world with professional production, mixing and mastering.
Two original English-language albums composed, produced, and released — available on SoundCloud and streaming platforms.
Singer-songwriter and multi-instrumentalist. Eclectic by nature — weaving Indian classical influences, pop, rock and folk into productions that refuse to sit still in one genre. Also the creative force behind The Yatrum Project, a collective exploring music, stories and visuals with serious themes, touched with irony.

No sign-up. No ads. Just the fretboard.
Open fretboard toolOriginal music, behind-the-scenes footage, and documentary work — all on the channel.
Nigher — sung in Bergamasco dialect
An Indian man singing in Bergamasco — the local dialect of Bergamo — turned out to be something people hadn't quite seen before. "Nigher" is a light-hearted, slightly absurdist take on racism. It got picked up by Eco di Bergamo, Corriere della Sera and Bergamo News.
Not something I planned. Just a song that seemed to need making.

Music & StorytellingProduced a year-long documentary on maize research for CREA (Italian government), excerpted on Rai national TV. Music videos, event coverage, concerts and documentary work.
I've built websites and done graphic work mostly for artists I've produced music for — it's easier to hand it all to one person. I'm comfortable with HTML, CSS, JavaScript and Xara, though I wouldn't call myself a designer first.
Living in Italy with English as my first language means people occasionally ask me to translate things. I've done it — documents, websites, bits of Hindi and Tamil too with help. It's one of those things that just came with the territory.
