About

Craft, curiosity,
and code

Vishal is a Principal iOS Engineer who loves building things from scratch. He has shipped production apps across fintech, health-tech, social media, and e-commerce -- each time designing architecture that scales and stays maintainable.

He's drawn to the "zero to one" phase of products: laying out module boundaries, automating tedious workflows with Swift scripts, and mentoring teams to move with confidence. Clean code and reusable components are non-negotiable.

Currently exploring the intersection of AI and mobile -- learning to orchestrate LLMs, agents, and AI tools to multiply productivity. The long-term goal is to ship products faster by blending engineering craft with AI-augmented workflows, always learning from others along the way.

Off the clock

The non-engineering bits

⚽
Football, trails & miles
Football on weekends, hiking when the mountains call, running when they don't. Treats the body like production code -- no shortcuts, no tech debt. // Leg day has no rollback strategy
🥬
Clean fuel only
Eats clean -- not "mostly", actually clean. No alcohol, no smoking, no cheat meals. Thinks of the body as a long-running process: garbage in, garbage out. // Strongly recommends others adopt this lifestyle too
🌎
Maps, money & power
Fascinated by geopolitical shifts, history, geography, and economic trends. Loves connecting the dots between why borders moved and where markets are headed. // Will derail any dinner conversation into a macro thesis
✈️
Passport stamps
Has collected sunburns across Southeast Asia and beyond. Believes the best debugging happens 35,000 feet in the air.
Maldives Thailand Philippines India (extensively)
📸
Photography
Enjoys capturing moments, mostly when traveling. The phone storage is 80% photos, 15% Xcode cache, 5% actual free space.
💡
Ideas & building
Constantly daydreaming about products to build. Has a notes app full of "million dollar ideas" -- shipping one would be nice. // TODO: actually ship one of these
