For founders going idea → live AI product. Fixed-price AI MVP in 8 weeks.
Proof: TalkDrill — 50,000 users on a voice AI pipeline we designed and shipped.
For teams whose web or mobile app needs AI features grafted in — search, summarisation, voice, agents — without rebuilding from zero.
Proof: PenLeap — AI rubric scoring added on top of a standard ed-tech stack, now serving 10,000+ UK students.
For teams that need a serious build, AI optional. Same senior engineers, milestone billing, named on the proposal.

Featured case study — our own product
TalkDrill is the AI English-speaking practice app the studio runs. 50,000+ users, 4.9★, live on Play Store and App Store. The hard part wasn't the UI — it was the voice loop.
Real-time spoken English practice means a sub-second loop from user speech → transcription → model response → spoken reply. Latency over 1.2 seconds breaks the conversation. Cost over $0.20 per session breaks the business.
Sub-second turn-around in production. 4.9★ average rating across 50,000+ users. The same architecture pattern transfers cleanly to conversational-AI customer service, voice-driven call coaching, and any real-time spoken interface.
ASR
Streaming speech-to-text with partial-result handling — composition starts before the user finishes speaking.
LLM
Context-windowed conversation memory per session; prompt-cached system layer keeps tokens cheap.
TTS
Streamed audio back to the device — playback begins before generation finishes.
Session state — per-user progress, scenario tracking
Mobile shell — streaming duplex audio, offline cache
Each component selected and tuned against latency and cost budgets.
30 / 40 / 30 split — kickoff / midpoint / delivery + 30-day support.

Read full policy →Three+ production AI systems shipped in the last 18 months — PenLeap, TalkDrill, ExamReady, AppliedView.
Read full policy →TalkDrill's voice pipeline: 11 weeks to production. 365 automated publishing workflows last year. Client portal: live in a month. Weeks, not quarters — here's the mechanism.
Claude-class coding agents, AI-assisted scaffolding, generated test suites — the same tooling we deploy for clients runs our own delivery. AI MVP in 8 weeks: 3× faster than the 6-month agency build.
AI writes the first draft; named senior engineers own the merge. Compression without slop — CI, code review, and a 30-day support tail on every milestone.
Fixed price, milestone-billed 30/40/30 — less than half the cost of a traditional agency build. What the tooling saves in hours shows up in your quote and your calendar, not our invoice.
“We brought Softechinfra in to ship our US property management platform from scratch. What we got was a senior team that scoped honestly, milestone-billed without surprises, and handed off a codebase our in-house engineers could maintain from day one. Eighteen months later the platform is still running on the architecture they designed — and we've recommended them to two other founders since.”
