Seniorengineering,withouttheagencyoverhead.
Techbylanz is a small, senior-led software studio. We ship end-to-end: research, design, build, and operate — for teams that need real engineering leverage, not a delivery pipeline.

— Founder story
Seven years, twenty‑five products, one obsession: shipping.
I started as an engineer building for early-stage teams — React and Node work that turned into full-stack ownership across web and mobile.
Over the last three years, most of my work has been AI-native: LLM-backed products, RAG pipelines, and automations that quietly move a business forward.
Techbylanz exists because most software teams don't need a bigger agency — they need a senior engineer who cares.

— Mission
Give ambitious teams the software leverage of a top‑tier product org — at the speed of a two‑person studio.
— Vision
Every business runs on custom software and AI. We help our clients get there first, and cleanly.
— Values
What we hold to.
Craft over volume
Fewer, deeper engagements. Software that lasts longer than the pitch.
Signal over noise
Weekly demos, honest metrics, and prose you can actually read.
Systems over one-offs
Design systems, typed contracts, reusable primitives — compound leverage.
Ship, then refine
Real users beat imaginary ones. Ship it, learn, iterate.
